Tornado kills ten in Mississippi

A powerful 1/2 to 1-mile wide tornado cut a path of enormous destruction across the state of Mississippi yesterday, killing at least ten and injuring dozens. It was the deadliest tornado in the U.S. since May 10, 2008, when an EF-4 tornado killed 22 people in Oklahoma and Missouri. The damage I've seen so far from photos of yesterday's tornado appears to be mainly of the EF-3 variety, though we will have to wait for the official damage surveys to be sure. The supercell thunderstorm that spawned the tornado or family of tornadoes maintained a continuous circulation from the time the tornado first touched down in Louisiana near the Mississippi border until the tornado reached the Alabama border. This is an extremely rare occurrence. If the 188-mile path of destruction across Mississippi was from a single tornado, it would rank as one of the longest tracks by a single tornado on record. The record of 219 miles is held by the deadliest tornado of all time, the great Tri-State Tornado of 1925 (though there is some dispute over whether this was one tornado or a family of tornadoes.) Our severe weather expert Dr. Rob Carver has a more complete analysis and imagery of yesterday's tornadoes.


Figure 1. Doppler radar storm-relative velocity of the mile-wide tornado that affected Yazoo City, Mississippi On April 24, 2010. This is an unusually wide and strong circulation for a supercell thunderstorm.

More severe weather expected today along the East Coast
The Storm Prediction Center (SPC) outlined a "Slight Risk" region of concern for severe weather today along the East Coast, from Maryland to Northern Florida. Yesterday, SPC had Mississippi underneath the first "High Risk" area of severe weather concern for the year. As usual, you can follow today's severe weather outbreak with our interactive tornado page and our severe weather page..


Figure 2. Severe weather reports for Saturday. Note the long line of red tornado reports extending across the state of Mississippi. These reports originated from a single supercell thunderstorm that spawned one or more tornadoes that carved out a 188-mile lone path of destruction across the state.

Basically, 2004 style tracks combined with 2005 style systems. Not bode well for the US this year, I pray this doesn't fold out. I still feel however that the most likely threat to the US is from the Caribbean. That TCHP in the Caribbean is already higher than 2009 was in July!

Both 2004 and 1998 were ominous.

As of now, landfall predictions are unknowable.

After going through Ivan in 2004 I would rather just go Fishing if you know what I mean LOL....
Quoting StormW:


Could have..but then I'd be lying. Just looking at the forecast setup, and if you read Draks posts, 1998 or 2004 tracks have a good prob. of panning out.

I know I read it but I wish them all out to sea... they are still rebuilding from Katrina, Rita and Ike much less to have another one to rebuild from....
just my thoughts....

Good evening.
Sorry to hear of the loss of life in that Tornado.
Would be interesting to learn of the accurate details of it. Sounds like a monster! 188 miles??

You can see that the north atlantic storm was definitely tapping into some tropical moisture. I think it didn't have enough organization or deep convection though.

You can also see the rotation over panama. looks like it's more in the carribean right now, actually.

Well, the Bermuda high is at a location that would not allow for too many fish storms and more land falling storms.
The Bermuda High could change its position substantially by the time we start tracking tropical cyclones.

Quoting SouthALWX:
the models were quite bullish on this event I thought. Most criticism prior to the event was that it was TOO hyped, not that it was under done. I felt the models did a good job. If you look at where they placed the the left exit region of the jet, it was almost EXACTLY where the Yazoo tornado tracked.
Overall I believe the mets provided good and timely warnings. Models did good too.

think about this. news said 200 homes were ruined by the tornadoes yesterday. how many homes would be destroyed by a cat 4 moving directly through miami?


More than 200 ... after Hurricane Andrew while driving back to the Keys, I gazed across a scene I will never forget. Nothing was standing south and west of Kendall Drive. I school bus rested atop a crushed roof of a house. I don't want to see this ever again.

Seems to be a lot of moisture building in the western Caribbean. I don't like everything turning north from that point. Still have to much shear. but look out late May early June although I don't see anything severe that early in the season.

My son has to drive back to Texas from Florida Thursday through Saturday. Are we in for a repeat of the last few days?


From what the NWS and GFS are showing the answer would be "yes". It does look to be a little farther North than this last mess we had yesterday.... Although the storms this time of year are hard to predict if you know what i mean

Actually, our NWS office was calling for this event nearly a week in advance. They did a great job forecasting this outbreak. I realize you're talking about the models, but according to the forecasters, the GFS and Euro did a nice job advertising this event.

I also agree from what I saw a week ago and what the NWS was saying they had it right....

Now another out break will be Thursday thru Saturday....

In that respect yes, but the number of storms could be more given SSTs.
SST's and dying El niƱo. We could have anywhere from 15 to 25 named storms. (25 seems a little extreme though, lol)

The line of storms that are moving through Central FL have slowed its southerly movement and appear to be stretching from west to east. New storms are forming off of the west coast from Pinellas northward. Looks like we may see a training effect for the next couple of hours.

Looks like 2004 looks like a better comparison track-wise due to the current forecasted placement of the Bermuda/Azores high.

The Destruction in Mississippi was ridiculous - The Models seemed off on this one. Up to a couple days before the event they really didn't show the threat.
