Deadliest U.S. tornado since 1953 rips through Joplin, Missouri, killing 89

The incredibly violent tornado season of 2011 struck another sickening blow last night, when a violent tornado carved a ½ – ¾ mile-wide path of devastation through Joplin, Missouri. At least 89 people died, hundreds were injured, and huge sections of the town virtually obliterated. Damage from the tornado is so severe that pavement was ripped from the ground, which is characteristic of a top-end EF-5 tornado with winds in excess of 200 mph. This was almost certainly a least an EF-4 tornado with winds over 166 mph, and the level of damage is so extreme that this is likely to surpass last month's Tuscaloosa-Birmingham tornado as the costliest tornado of all-time.


Figure 1. Cars stacked on top of each other in front of the heavily damaged St. Johns Regional Medical Center after the May 22, 2011 tornado in Joplin, Missouri. Note the pavement ripped up from the road and piled in front of the cars. Tornadoes powerful enough to rip up pavement are frequently classified as EF-5 with winds in excess of 200 mph.

The huge supercell thunderstorm that spawned the Joplin tornado formed over extreme southeast Kansas yesterday afternoon, along the boundary between warm, moist air flowing northwards from the Gulf of Mexico, and cold, dry air moving south from Canada. NOAA's Storm Prediction Center (SPC) had put the region in its “moderate risk” region for severe weather. As the supercell moved into Southwest Missouri, it spawned the tornado that roared through Joplin at 5:45pm CDT. This storm generated other tornadoes, straight-line wind damage, and flash flooding from torrential rains that exceeded six inches as it moved east southeast across Southwest Missouri. SPC recorded 48 preliminary reports of tornadoes yesterday, bringing the 2-day total for the current outbreak to 70. A tornado also killed one person and injured 22 in Minneapolis Sunday. Separate tornadoes killed one person each in Andice, Texas and Reading, Kansas on Saturday—the first tornado deaths in the U.S. since the April 25 – 28 Super Outbreak.

Deadliest tornado since 1953
Yesterday's Joplin, Missouri tornado is the deadliest single tornado in the U.S. since June 10, 1953, when 94 people died in the Worcester, Massachusetts tornado. The previous deadliest tornado in the past 50 years occurred just last month, when 65 people died in the Tuscaloosa-Birmingham EF-4 tornado in Alabama. This year's tornado death toll now stands at 455, making it the deadliest year for tornadoes in the U.S. since 1953, when 519 people died. The deadliest year was 1925, with 794 deaths. That was the year of the deadliest U.S. tornado of all-time, the great Tri-State tornado, which killed 695 people in Missouri, Illinois, and Indiana.

More severe weather today
NOAA's Storm Prediction Center has placed a large section of the Midwest U.S., including portions of Oklahoma, Kansas, Missouri, Illinois, Ohio, Michigan, and Pennsylvania, in its “moderate risk” region for severe weather today. The threat of tornadoes will not be as great today as yesterday, with today's main threat being large hail and damaging straight-line thunderstorm winds. However, I do expect we will see a dozen or so tornadoes today, and residents of the at-risk area need to keep in mind the deadly history of this storm system. The severe weather threat will continue into Tuesday, when additional tornadoes are likely over Oklahoma, Kansas, and Southwest Missouri. A severe thunderstorm roared through Joplin between 8:30am and 9am CDT this morning, bringing heavy rain, small hail, and wind gusts to 36 mph. Undoubtedly, this storm frayed some nerves, and the city will remain at risk of seeing more severe thunderstorms through Tuesday night.

The most remarkable audio I've ever heard of people surviving a direct hit by a violent tornado was posted to Youtube by someone who took shelter in the walk-in storage refrigerator at a gas station during the Joplin tornado. There isn't much video. We won't see a lot of spectacular videos of the Joplin tornado, since it was wrapped in rain and difficult to see.

Listen to my 12-minute interview on the historic April 2011 tornadoes for EarthSky.org, which aired on NPR earlier this month. I discuss how climate change might impact severe weather and tornadoes.

Our weather historian, Christopher C. Burt, has an excellent post on The World's Deadliest Tornadoes.

My 2008 post, Are tornadoes getting stronger and more frequent? The answer is--we don't know.

Helping out tornado victims
For those who want to lend a helping hand to those impacted by the widespread destruction this spring's severe weather has brought, stop by the Red Cross website, or portlight.org blog. Portlight has been very active bringing aid to the victims of this year's tornadoes.

I hope we hear more of these stories today:

[Updated at 1:39 p.m.] Rescuers have pulled five families from beneath the rubble in Joplin, Missouri, where a tornado devastated up to 30% of the city, according to Gov. Jay Nixon.

"We still believe there are folks alive under the rubble and we are working hard to save them," Nixon said Monday afternoon, nearly 19 hours after the tornado struck.

92L seems to have a very pronounced spin to it. I wonder what the chances are for it to loop to the southeast, south and then move west.

VALID 241200Z - 251200Z

...THERE IS A MDT RISK OF SVR TSTMS FROM NWRN TX TO SRN NEB...

...THERE IS A SLGT RISK OF SVR TSTMS SURROUNDING THE MDT RISK OVER
THE SRN/CNTRL PLAINS THROUGH THE OH/TN VALLEY TO SRN NY...

...TORNADIC OUTBREAK POSSIBLE ACROSS THE CENTRAL AND SOUTHERN PLAINS
TUESDAY. AN UPGRADE TO HIGH RISK MAY BE WARRANTED AS SITUATION
BECOMES MORE CERTAIN...


A CLASSIC PLAINS TORNADIC OUTBREAK APPEARS TO BE EVOLVING ACROSS THE
CNTRL/SRN PLAINS...ESPECIALLY FOR KANSAS AND OKLAHOMA. LATEST MODEL
GUIDANCE IS CONSISTENT REGARDING THE PROGRESSION OF A VERY STRONG
MID LEVEL SHORTWAVE TROUGH...CURRENTLY DIGGING ESEWD ACROSS SRN
CA...INTO THE SWRN U.S./SRN ROCKIES BEFORE EJECTING INTO THE PLAINS
BY PEAK HEATING. A VERY DIFFLUENT UPPER FLOW REGIME WILL OVERSPREAD
THE PLAINS AS 30-60M 12HR HEIGHT FALLS EDGE EWD. ADDITIONALLY...H5
SPEED MAX APPROACHING 80-90KT...AS NOTED IN THE GFS...WILL RACE TO A
POSITION OVER NWRN TX/SWRN OK BY 25/00Z WHICH WILL GENERATE VERY
STRONG SHEAR ACROSS THE WARM SECTOR FOR AREAS NEAR THE RED RIVER
REGION...NWD INTO KS AND EVEN SRN NEB. NEEDLESS TO SAY A VERY
DYNAMIC SHORTWAVE TROUGH SHOULD TIME FAVORABLY FOR RAPID SEVERE
THUNDERSTORM INITIATION ALONG/AHEAD OF THE DRYLINE AS ATMOSPHERIC
HEATING IS MAXIMIZED.

EARLY IN THE MORNING A FEW THUNDERSTORM CLUSTERS MAY BE ONGOING
WITHIN THE STRONGEST ZONE OF WARM ADVECTION FROM KS EWD INTO MO AND
THE LOWER OH VALLEY. THIS REGION OF ASCENT AND STORMS MAY
TEMPORARILY FORCE A CONVECTIVE OUTFLOW INTO NRN AR...NWWD INTO SRN
KS. HOWEVER...A NWD RETREAT IS LIKELY TO AT LEAST THE I-70 CORRIDOR
IN KS AS DAYTIME HEATING OCCURS ACROSS THE WARM SECTOR. FOR THIS
REASON IT APPEARS A VERY UNSTABLE AIRMASS WILL BE IN PLACE FROM NRN
TX INTO SRN KS WHERE SBCAPE VALUES COULD EXCEED 5000 J/KG WHERE SFC
DEW POINTS HOLD IN THE LOWER 70S. FORECAST SOUNDINGS ACROSS THE
WARM SECTOR EXHIBIT CLASSIC TORNADIC SUPERCELL STRUCTURES WITH
STRONG LOW LEVEL HELICITY ACROSS KS/OK WITH DEEP LAYER SHEAR ON THE
ORDER OF 50-60KT. BY MID AFTERNOON...STRONG HEATING SHOULD BE NOTED
ALONG/WEST OF THE DRYLINE FORCING TEMPERATURES TO SOAR WELL INTO THE
90S...EFFECTIVELY REMOVING INHIBITION FOR CONVECTIVE DEVELOPMENT
WHERE LOW LEVEL CONVERGENCE IS MAXIMIZED. AT THIS TIME IT APPEARS
TSTMS SHOULD INITIATE ALONG THE DRYLINE BY 21Z...ALTHOUGH ACTIVITY
COULD DEVELOP MUCH QUICKER WITHIN THE STRONGER FORCING ACROSS THE
CNTRL HIGH PLAINS TO THE NORTH-EAST OF THE SFC LOW WITHIN STRONGEST
UPSLOPE FLOW.

Hi guys.

I live in Springfield and my brother lives in Joplin and was one of the unlucky majority that lost their home. But thankfully he is fine beyond some scratches.

I used my GIS software and some reports from people in the area to map the path of destruction to the best of my ability at a desk. You can use Google Earth to view the KML file that I posted on a Google Earth thread as well. Link to KML

Anyof you more weather savvy few out there find the actual path off the radar?

They would also shear off if the chopper rolled a couple of times, which is likely.


yes on the sheared off due to rolling, i just would have expected at least one bent vs all sheared. a further down post about it taking a brief unmanned flight is highly likely. it was just a small detail, but to me a prime example of wind and hails power. super note is the loss to the hospital at a time when they could really use the medivac.

Yep. And considering how far the chopper is from the hospital - and the fact that most helipads are on the roof... I'm thinking the chopper had a very brief unmanned flight, followed by a hard and dizzying landing.

sorry for the late comment on your previous picture, but did you notice that all 4 props are sheared off? i don't know how that could have happened unless the prop free wheels in wind (i'm a fixed wing gal, not rotary). i just hope the props weren't sheared because they were flying / attempting a take off or landing during the storm. that is a scary photo. have family in joplin - on a farm outside the city - and am just waiting on confirmation that all is okay with them. small fact: this is a largely minninite (excuse spelling) area. the last time i was there it was amazing to see large flat bed trailers with grain being pulled down the roads by a team of LARGE draft horses. my family are cattle & goat farmers there.

They would also shear off if the chopper rolled a couple of times, which is likely.

I beg to differ on that! Have you seen any of the pictures from Hurricane Andrew!? Did you see how it decimated all the homes, etc.? Look at the pictures. The damage was just as bad!

Hurricane Andrew was rated a category-5, which means it had sustained winds near 165-MPH. In tornadoes, there is also a scale called the Fujita scale. Tornadoes, however, are measured by peak gusts, not sustained winds. Peak gusts in Andrew exceeded 200-MPH, in a tornado, such a gust would rate it a strong F3 (on a scale from 0 to 5) to maybe a borderline F4. Such tornadoes are the mile-wide "monsters" we rarely see in the Great Plains. Imagine such a tornado 20 miles wide? That's basically the damage seen in Andrew's 20 mile wide eye wall.

Seems like what really the model is showing and seems like it has credibility, is a big amount of WV that invades the Caribbean... one week from now... About that new system, could be that new wave going into SA, that will then move into the Carib.
