Via a thread post on Stormtrack, Dan Robinson and Tim Vasquez have outlined storm chasing fatalities since the inception of storm chasing.
The above bar graph graphic,
produced by Robinson, illustrates all the storm chasing fatalities (which is
fifteen) since the inception of storm chasing.
Robinson, with the help of Vasquez, wrote extensively about eight separate incidents which lead to the deaths of storm chasers’.
2nd April 1984:
The first “in the field” chaser death, Christopher Phillips was a twenty-one
year old OU meteorology student from New Jersey. Phillips died when he swerved
to avoid a rabbit and his car rolled over into a ditch in Oklahoma.
11th July 2005:
Norman, Oklahoma resident Jeff Wear was killed on Interstate 20 near Kilgore,
Texas after he hydroplaned in heavy rain and struck a flatbed truck head-on.
Wear was returning from a chase to intercept Hurricane Dennis.
6th June 2009:Fabian Guerra of Chicago was killed on
Interstate 80 in Iowa when he swerved to avoid a deer, crossed the median and
struck an oncoming tractor-trailer in the early morning hours of June 6th.
Guerra was heading to Nebraska to meet up with two other chasers for a chase in
the area later on that day.
4th February 2012: Andy Gabrielson was killed on Interstate 44 near Sapulpa, Oklahoma in a head-on collision with a drunk driver going the wrong way on the highway. Gabrielson was on his way home from a chase earlier on in Oklahoma.
31st May 2013: Tim Samaras, Paul Samaras and Carl Young were killed when the El Reno, Oklahoma Tornado overtook their vehicle. Richard Henderson, resident of Oklahoma, was killed by the Tornado when he went out near his home to observe the storm and take pictures. Something we didn’t know! A fifth fatality involving a likely chaser was uncovered by researchers studying the Tornado and its impacts.
12th July 2015: David and Mildred Frank were killed when a storm chaser ran a stop sign near the town and collided with their vehicle. We have to stipulate that the Franks were not chasers. The chaser survived with minor injuries and was later criminally charged, receiving a ninety-day suspended jail sentence and one year probation1.
28th March 2017: Corbin Jaeger, Kelley Williamson and Randall Yarnall died
when the Yarnall/Williamson vehicle ran a stop sign near Spur, Texas and
collided with Jaeger’s vehicle. This particular incident has been in the news
recently, as Jaeger’s family has filed a civil lawsuit against The Weather
According to the thread post, Yarnall/Williamson were chasing and live streaming in “official capacity” for The Weather Channel at the time of the crash.
Thank you to Dan Robinson and Tim Vasquez for putting this together. We learnt a lot from it and we think others will as well. That’s why we’re writing about it! We recommend that you read the replies in the thread, it’s worth it.
FYA: There is another thread on Stormtrack which lists/memorialising all storm chasers who have passed on – read here.WE URGE YOU TO TAKE A LOOK AT IT!
1: A subsequent civil suit by
the family yielded a one hundred thousand dollar judgement. Fatal accidents
have happened at the same intersection before, and residents had submitted
previous complaints. The chaser despite being in the vicinity of severe storms
and posting about them to his Facebook page prior to the accident, states he
was not “actively” chasing at the time of the accident.
El Reno, Oklahoma mayor Matt White said during a press conference that “there have been two fatalities at this point,” adding that officials are working to let relatives know.
White said search and rescue efforts are continuing – even when we’re writing this.
National Weather Service (NWS) meteorologist Rick Smith told The Associated Press that the likely Tornado hit last night as a significant storm swept through the state. Survey crews are expected on scene to determine the severity of the damage to the town.
The roadside hotel, American Budget Value Inn was destroyed by the Tornado. Photos that emerged shortly after the event showed emergency crews going through rubble after an element of the roadside hotel’s second story collapsed into a pie of debris – scattered about the first floor and parking area.
Mobile homes at the Skyview Estates adjacent to the roadside hotel suffered significant damage, as was a part of a car dealership which is nearby.
In a strongly written and rightly worded article, Matthew Cappucci of the Capital Weather Gang shared a perspective on the mobs/aka noobs ruining storm chasing.
At the start of
his perspective piece, Cappucci stated that he heard “grumblings about the
downsides of storm chasing for a long time” – suffice to suggest we’ve heard the
Those downsides include: poor driving habits, traffic jams as cars converge near significant storms.
Cappucci concluded on this particular subject of the downsides of chasing by stating: “It had always been on my mind, but four years of venturing to the Plains had taught me it was just something with which I’d have to live. I’ve always brushed it off as an unavoidable by-product of chasing.”
Cappucci moved on to the subject of
which this article is based upon – YESTERDAY’S SEVERE WEATHER RISK!!!
started on the above mentioned subject by stating “he witnessed first-hand the
practices” that would drive him away from storm chasing.
Cappucci put a
six bullet point list on some of the things he’s encountered – which can be
vehicles parked perpendicular to roads – blocking major intersections.
chasers with red/blue police lights, “pulling over” others to clear their path
to the storm.
jams two hundred cars deep.
parking on/in the road to take photographs – blocking traffic.
“barrelling” down a one-lane road at stupid speeds in our opinion – ninety miles
driving on the wrong side of the road.
captured by veteran chaser, Daniel Shaw perfectly illustrates a scenario which
played out on Monday – see below.
Suffice to say, the dangers speak for themselves.
In his perspective piece, the Capital Weather Gang contributor stated his biggest fear wasn’t weather related; it’s other chasers.
Yesterday, an incredibly significant and photogenic Tornado swept passed Mangum, Oklahoma – find our articles on that here. here and here
Highway reported just one injury, thank god. It wasn’t caused by the adverse
weather conditions… It involved two vehicles with storm chasers…
You can read the rest of Cappucci’s perspective piece here, we wanted to give you a taste. Now on to our take…
chasing community has been unbelievably lucky when it comes to the lives of
1: Chasers have died in past traffic/Tornado
incidents, however out of respect for family, friends and colleagues, we did
not want to mention their names in this particular piece. However, our
thoughts, prayers and love remain with above mentioned individuals.
believe the crux of the issue comes from the amount of chasers on the road. Then
it comes down to the do it yourself storm chasers/amateur that have been
spurred on by popular TV shows, Netflix documentaries etc. Not forgetting to
safe to suggest it’s not just amateur chasers contributing to the issue.
Professional storm chasers are also contributing to the issue – even making it
worse! Sorry to say…
…With a lot of competition
in the industry, many are taking it to a whole new level in order to get the
best, most up close video. This tends to mean taking needless risks, not to
mention putting others at risk. You know Cappucci makes an excellent point on
“Branding things as “extreme” gets clicks and views. That makes money. And across the board, we’re much more likely to celebrate an “extreme storm chaser” than we are a “safe storm chaser.” You’re not going to turn on the TV and see a headline that reads “storm chaser records tornado from a safe distance.”
Matthew Cappucci, Capital Weather Gang
significant amount of money involved, the dangerous and somewhat shocking
behaviour looks set to get worse. Illegal driving can’t be policed, why? They’re
dealing with the severe weather situation. You can’t limit the number of
chasers, tourists that go chasing…
2: However, we’ll come on to that
It’s going to
have to take something drastic in order to hastily get discussion underway in
ways the industry change.
2 One idea we had was that chasers would
have to get a special type of licence which allowed them to chase3. Here
in the UK, you have to have a special licence to drive a lorry (semi-truck) for
In order to get that licence, you’d have to take an enhanced & relating test. Why can’t the same be for chasers? It’s an idea we’re going to sleep on and comeback to post in this blog.
FYI: The definition of noob can be found below:
“A person who is inexperienced in a particular sphere or activity, especially computing or the use of the Internet.”
A survey conducted recently of the southeastern United States illustrates that nearly half of residents that live in mobile homes don’t know where to shelter during a Tornado and many are not getting the resources they need to survive one.
illustrates that residents across the southeastern United States, where mobile
homes make up almost twenty per cent of house, don’t have the resources or
information they need to safely respond to a Tornado. That’s frightening!
More than half
of mobile home occupants don’t know the best place to take shelter. A number don’t
have a community shelter to get to. Mobile home residents “don’t perceive”
Tornadoes as any worse a danger than their neighbours in permanent homes.
indicates that nationwide, they are nearly twice as likely to die in a Tornado.
Talking to Earth & Space Science News (EOS), University of Maryland risk
communications researcher, Brooke Liu said:
“We know a lot about how corporations can protect their reputations, but we know comparably a lot less about how governments can help protect the public during extreme events.”
Brooke Liu, University of Maryland risk communications researcher
colleagues, Liu conducted a survey of Tornado awareness among about three thousand
mobile and permanent home residents in twelve states throughout the southeast.
The findings of the survey were published on
the 29th March in Weather,
Climate and Society, indicate that the current communications strategies
have a lot of room for improvement.
Liu spoke to EOS in an interview, which you can read here. We highly recommend that you do have a read, it’s a fascinating!
On the 13th May 1980, A F3/EF3 Tornado struck the city of Kalamazoo, Michigan. The Tornado first touched down at 4:00pm eight miles of the city limits, it steadly moved eastward through downtown Kalamazoo.
dissipated east of the city at around 4:25pm. So essentially, the Tornado was
on the ground for twenty five minutes.Twenty five minutes
had passed by, however the devastation left in the wake of this Tornado was substantial.
Five people died, seventy nine injured and over fifty million dollars in property damage. William Milliken walked through the area hours later, and suggested the following: “It reminds me of a bombed

…We didn’t particularly want to make this a wordy article, however we wanted to give this Tornado a substantial introduction.
Now you’ve read about it, now relive the Kalamazoo, Michigan Tornado of May 13th 1980 thru the lens of a camera in the videos below.
Find an incredible gallery of photos of damage caused by this Tornado here.
This Tornado was one of many that struck during the Red River Valley Tornado
outbreak of the 10th April 1979…
will be producing a separate article on this outbreak in due course. You can
find more out on the Wichita Falls, Texas (TX) storm itself here.
F4/EF-4 Tornado that struck Wichita Falls, TX formed several miles southwest of
the city in Archer County, travelling over mostly open land.
the Tornado turned east-northeast, it entered Wichita County – damaging a
handful of rural homes, string of high voltage towers.
into the city of Wichita Falls, the Tornado first struck Memorial Stadium and
McNiel Junior High School, severely damaging both buildings (#1 on the damage
path diagram below).
The Tornado’s formation and its movement towards the stadium and high school was captured on camera by Wolfgang Lange from the front of his apartment complex (#2 on the damage path diagram) – see in the photos below.
capturing the last photo of the Tornado, Lange retreated to the complex’s
laundry room and hid between heavy commercial washers and dryers. Luckily, he only
suffered minor injuries.
Northeast of Lange’s apartment complex, on the first street of houses, a man by the name of Robert Molet also captured the Tornado on camera as it approached (#3 on the damage path diagram) – see in the photos below.
Lange’s view, as you can see in the above photos, Molet did not have an unhindered
view of the Tornado – did not immediately recognise the F4/EF-4 wedge.
stood in his backyard driveway and captured the destruction of the above
mentioned apartment complex and the beginning of his neighbourhood being destroyed.
carried on taking photos until the wind blew him into his garage. Although, his
house was completely destroyed, Molet escaped with only minor injuries –
protecting him from the worst of the winds and debris.
first deaths caused by Tornado were recorded at the already mentioned apartment
complex and adjoining housing area.
east-northeast, the Tornado severely damaged commercial buildings along
Southwest Parkway, including total devastation of the Southwest National Bank Building
except its vault (#4 on the damage path diagram).
of Southwest Parkway, the F4/EF-4 wedge destroyed many homes in the Western Hills
(DR). Further eastward, many houses in the Faith Village were destroyed, Ben
Milam Elementary School was severely damaged (#6 on the damage path diagram).
The Tornado was captured on camera from the south of the city by Pat Blacklock – see in the photos below (#5 on the damage path diagram).
As you can see in the last few photos above,
the gust front/strong west winds to the south of the Tornado can be seen
producing waves on Lake Wichita – kicking up spray from the lake.
As the F4/EF-4 wedge crossed Kemp Boulevard, a number of commercial business were destroyed – resulting in several deaths. The Tornado’s most destructive winds missed the Sikes Senter Shopping Mall to the south, but a handful of stores were damaged.
the above mentioned shopping mall, the Tornado crossed a greenbelt area, “skirted”
Midwestern State University on the south side – severely damaging more housing
From the Ligon Coliseum of the University, Professor Joe Henderson captured the Tornado on camera (#7 on the damage path diagram) – see in the photos below.
The F4/EF-4 wedge was also captured on camera by Troy Glover from the roof of the Bethania hospital (#8 on the damage path diagram) – see in the photo below.
number of people tried to outrun the Tornado as it crossed the south side of
the city by getting in vehicles and driving east of Southwest Parkway – north on
US Highway 281 and east on US Highway 287.
Tornado blew many of those vehicles off the above mentioned highways, resulting
in numerous deaths.
F4/EF-4 wedge took the lives of forty two people in Wichita Falls, twenty five
deaths were vehicle related and sixteen of the twenty five deaths got in vehicles
to outrun the Tornado.
leaving the east side of the city, the Tornado destroyed the Sun Valley housing
area, the Sunnyside Heights Mobile Home Park and several large commercial
businesses including the Levi Strauss Plant – iconic jean maker.
of Wichita Falls, the Tornado trekked into Clay County. Not only did it enter a
different county, it changed its appearance.
As seen in the photos below, captured by Winston Wells, the Tornado became multivortex (#10 on the damage path diagram). At one time, the F4/EF-4 wedge displayed as many as five satellite vortices.
this stage of its life, the Tornado did extensive damage just south of Dean and
near Byars, destroying a significant number of rural homes, but thankfully
causing no deaths.
The grief and devastation caused by this Tornado is almost unthinkable
particular type of Tornado event is unheard of! A violent Tornado tearing
through an eight mile section of a city.
addition to the forty two deaths caused directly by the F4/EF-4 wedge, three
more people died of heart attacks/illnesses during the stress of the Tornado’s
life. The number of reported injuries approached almost eighteen hundred
however additional injuries were never recorded.
In 1979 dollars, total property damage
in the city was estimated at four hundred million.
three thousand homes were destroyed and another were damaged. One thousand
apartment units/condominiums were destroyed and another one hundred and thirty
Around one hundred and forty mobile homes were destroyed, two schools were obliterated and eleven others suffered significant damage. Over one hundred commercial businesses were destroyed, some of which were large businesses/manufacturing – including Levi.
That concludes our in-depth overview of the Tornado. Now, relive the Tornado in videos below.
It was a terrible Tuesday! On the 5th May 1964, a historic, destructive and deadly Tornado event affected a number of counties within central and eastern Nebraska.
Two particularly damaging/significant Tornadoes touched down, one was rated an F5/EF-5 and the other F4.
It’s suffice to say, the above mentioned F5/EF-5 Tornado travelled nearly seventy miles from eastern Adams County to northwestern Butler County is the last F5/EF-5 Tornado recorded in Nebraska. With that being said, let’s get into an overview of the Tornado event.
For some residents in central/eastern Nebraska, 5th May 1964, started out like any other day. However, by sunset, it would be a day of total destruction. During the afternoon, severed thunderstorms developed and quickly pushed northeast.
of these storms produced an F4/EF-4 Tornado touched down initially in
southeastern Greeley County and destroyed much of Wolbach and caused several injuries
– thankfully and fortunately no one died.
It’s safe to say, the biggest and most destructive Tornado was yet to come. By 5:00pm, a Tornado touched down just southeast of Hastings and developed into an F5/EF-5. Two people were killed by this Tornado a farm three miles northwest of Bradshaw…
…There were also numerous injuries,
including fifteen people near Shelby.
several towns along the way which were spared a direct hit, including Hampton,
Bradshaw, Benedict, Stromsburg and Shelby. Suffice to say there was complete
destruction of all farmsteads in the direct path.
It was a significant and powerful Tornado that completely destroyed at least a dozen of these farms within the first thirty miles of its track. The Tornado width was one quarter of a mile wide, sometimes two – three separate damaging funnels extended from the same cloud.
preceded, accompanied and followed the Tornado touching down. The Tornado
lifted near Bellwood in Butler County, the Tornado briefly touched the ground a
few times in the next forty miles.

this video is the EF-4 that struck Rochelle/Fairdale on the April 2015. Read
our recent article on this Tornado here.
terrifying video below, watch the moment a powerful Tornado destroys a couple’s
house… WHILST HE’S IN IT!!!
As you may have
seen, a message appeared at the start of the video. In case you missed it, you can
read in full below.
“The video was shot by Mr Clarence “Clem”
Schultz from the second story of his home in Fairdale, IL on 9th
April 2015. Though Mr Schultz survived, he had a number of very serious
injuries. Unfortunately, his wife and next door neighbour died in this event.
PLEASE do not attempt to video or take
photos of a Tornado as it approaches your location. Please follow National
Weather Service warning advice: “Move to an interior room on the lowest floor
of a sturdy building and avoid windows.
If in a mobile home, a vehicle, or
outdoors, move to the closest substantial shelter and protect yourself from
flying debris. It is your life… and your
responsibility to protect it.”
The video was captured by Clem Schultz on the day the Tornado struck – 9th April 2015. It’s suffice to say this video gained a lot of attention.
The April 2011 super Tornado outbreak was one of the biggest, deadliest and most destructive severe weather and Tornado outbreaks in the U.S. Suffice to say some of a handful of the Tornadoes that touched down during the outbreak struck heavily populated areas.
Regardless of alerts well in
advance and short term warnings, the Tornadoes/storms killed three hundred and
twenty one people and injured almost three thousand people, according to National
Oceanic and Atmospheric Administration (NOAA – Storm prediction Center – SPC).
Nearly three hundred and fifty
Tornadoes touched down in around of the south, Midwest and northeast states of
the U.S. A majority of the Tornadoes that touched down during the April 2011 super
outbreak happened on the 27th April, according to the National
The most destructive Tornado, a multiple-vortex EF-4 Tornado, which took the lives of sixty five people and injured more than one thousand people alone swept through Tuscaloosa and Birmingham, Alabama during the afternoon/evening on the 27th April.
Suffice to say, within a
matter of minutes, ten per cent of Tuscaloosa was destroyed and more than one
thousand six hundred people were left homeless – including the students of
University of Alabama. It has to be said, the above mentioned Tornado was one
point five miles wide with winds of one hundred and ninety miles per hour.
The Tornado was on the ground for more than eighty miles.
It has to be stated: The same
supercell thunderstorm that produced the Tuscaloosa and Birmingham Tornado went
onto to spawn other Tornadoes that “skipped” along a three hundred and eighty
mile long path from Mississippi to North Carolina.
Three EF-5 Tornadoes, twelve EF-4
Tornadoes and twenty one EF-3 Tornadoes struck during the April 2011 super
Tornado outbreak. Some of the violent storms coincided areas that were hit with
severe weather and Tornadoes earlier in the month. April 2011 was a busy month!
A destructive and deadly
Tornado outbreak took place on the 14th – 16th April,
when one hundred and seventy eight Tornadoes touched down and resulted in the
deaths of almost fourty people across parts of the Plains, south and eastern
In closing, April 2011 saw a
record seven hundred and fifty Tornadoes strike the U.S, according to the SPC –
records go back to 1950.
We didn’t particularly want to make this a wordy article, however we wanted to give this significant outbreak a well-balanced and detailed introduction. Now you’ve read about it, now relive the April 2011 super outbreak thru the lens of a camera in the videos below.
Find an extensive video playlist of the Hackleburg/Phil Campbell EF5 Tornado below.
Furthermore, TV coverage and documentaries in regards to this outbreak can be found below.
UPDATE: A reader brought it to our attention that Smithville, Mississippi was struck by an EF-5 Tornado on the 27th April 2011 – watch two videos of the Tornado below.
Here’s an overview on the Tuscaloosa/Birmingham EF-4 Tornado…
Tornado was spawned by a supercell thunderstorm which initiated in Newton
County, Mississippi at 2:54pm (CDT), it dissipated in Macon County, North Carolina
at around 10:18pm (CDT).
supercell thunderstorm lasted around seven hours and twenty four minutes –
travelling approximately three hundred and eighty miles producing several
significant strong/violent Tornadoes along the way.
EF-4 Tornado initially touched down in northern Greene County, Alabama (AL) and
moved northeast through southern Tuscaloosa and western Jefferson counties,
where it caused devastating damage to portions of the city of Tuscaloosa and
western suburbs of Birmingham, AL. The Tornado lifted northeast of downtown
Tornado entered Tuscaloosa County, just north of CR 60, west northwest of
Ralph, and moved northeast causing tree damage and minor building damage which
is consistent with an EF-2 Tornado.
Tornado intensified as it crossed the Black Warrior River, north of interstate
20 and approached Tuscaloosa to a violent EF-4. As the Tornado approached
interstate 359, a handful of buildings were destroyed – including Tuscaloosa
County Emergency Operations Centre.
15th street east and McFarland Blvd east, several small restaurants
and stores were destroyed, with only a wall or two standing. The Tornado
completely devastated the Cedar Crest neighbourhood just north of 15th
street, levelling many cinder block homes and killing three people.
Tornado then crossed McFarland Blvd, where is destroyed more stores and restaurants.
The EF-4 crossed McFarland Blvd in the Alberta City community. Alberta
Elementary School was almost completely destroyed, with only a few walls still
nearby apartment building was reduced to rubble. The Alberta Elementary School
suffered nearly complete destruction with no walls standing and a pile of
debris on the foundation. Cinder block construction homes in the surrounding
neighbourhood were completely destroyed.
Tornado continued northeast and struck the Chastain Manor Apartments at the
north end of 34th Ave east – completely destroying a brand new two
story apartment complex. It has to said, a small club house anchored to a
foundation was completely destroyed – swept from the foundation.
Comparable devastation to homes and businesses was eminent along both sides of CR 45 near 1st street east and locations to the northeastward. East of Holt, the Tornado path width widened from zero point five mile to one mile.
Tornado crossed Holt Peterson Road just northwest of Clinker Road, where two
homes were completely destroyed. ALMOST! All trees were blown down or snapped
in the vicinity, as well as in the bottom of a narrow ravine.
EF-4 continued to Holt Lock and Dam Road near its intersection with Recreation
Area Road where it caused significant damage to a restaurant as well as a
number of boats. Several injuries were reported in this area.
The Tornado moved northeastward and weakened an EF-3 rating. As its path narrowed to zero point five mile, the Tornado passed north of Brookwood, near the intersection of Hannah Creek Road and CR 99 and moved into western Jefferson County, four miles north of Abernant…
…With that being said, we’re going to leave our overview here. Read more about the Tuscaloosa/Birmingham EF-4 Tornado here. Below find a handful of relating facts:
Estimated maximum wind: one hundred and ninety miles per hour.
Injuries/deaths: one thousand five hundred injuries/sixty five deaths
Damage path length: eighty one miles
Maximum path width: two thousand six hundred yards (one point five miles) when crossing I-65.
Approximate start point/time: 33.0297/-87.9350 at 4:43pm
Approximate end point/time: 33.6311/-86.7436 at 6:14 pm
With that being said, relive the Tuscaloosa/Birmingham Tornado in the videos below.
In this post however, we’ll be focusing on the Parkersburg, Iowa EF-5 Tornado – which struck on the 25th May 2008 – find out more at the bottom of the article.
In the surveillance camera video below, watch the May 2008 Parkersburg, Iowa Tornado completely obliterate a home.
The surveillance camera footage was captured by the surveillance camera at First State Bank – bank’s drive-up ATM – in Parkersburg.
The above mentioned Tornado tore a forty three mile-long path across the counties of Butler and Black Hawk in Iowa.
The EF-5 took the lives of nine people, injuring dozens and causing several millions of dollars worth of damage.
The Tornado began near the Butler and Grundy County line, two miles south of Aplington, Iowa at 4:48pm (CDT).
The Tornado grew quickly in size and intensity over the next several minutes as it approached Parkersburg.
The Tornado was nearly three-quarters of a mile wide as it moved through the southern end of Parkersburg at 4:56 (CDT).
A third of the town experienced devastating damage with nearly two hundred homes completely destroyed.
The Tornado maintained it’s size and intensity as it moved through New Hartford, Iowa. At 5:09pm (CDT), the severe weather event moved just north of New Hartford, once again causing incredible structural and tree damage.
The Tornado weakened east of New Hartford with lesser damage as it pushed through portions of northern Black Hawk County – north of the cities of Waterloo and Cedar Falls.
During the weak phase of the Tornado, the parents supercell thunderstorm produced significant straight line winds from a large rear-flank downdraft (RFD) just south of the Tornado’s path.
Wind speeds of up to one hundred miles per hour were produced simply by the RFD, with a wind gust to ninety three at 5:37pm (CDT) measured at the Waterloo Airport.
The Tornado re-intensified and grew nearly one and a half miles wide north of Dunkerton, Iowa causing significant damage to a farmstead there. The Tornado dissipated just before leaving Black Hawk County at 5:50pm (CDT).
