Severe Weather Threat. April 21st-25th, 2010 High Risk!

[Stephanie]

Live stream ABC 33/40 out of Birmingham reporting storm shelters opening up at Talledega.

If you've ever been to a NASCAR race...or driven by a track while a race weekend is going on...then you know how dangerous this situation is.

They have closed the track and the stands will be empty.

But there are tens of thousands camping around the track in motorhomes, RV trailers, truck campers, and tents. And that many people can't be evacuated quickly. (My wife and I sat in a parking lot at Texas Motor Speedway for four hours one time without the wheels ever moving.)

If a storm were to threaten the track, there would be countless people there that would literally be "sitting ducks".

We'll just have to hope that a tornado doesn't come out of any storms that are sure to hit there.

Should be a checkbox on the right side of the screen...set it to 'smooth'.

Possible tornado touchdown locations from awhile ago near Meridian MS

Those are probably all from the same tornado and sounds like an intense one.

WMC-TV from Memphis is tracking the torn-warned cell west of the city.

I am sure there have been more tornadoes that have been reported as wind damage as well, they can be hard to see!!!

[Dave]

Tornado warnings are stacking on top of each other in various locations, picking them out as I go. I agree, has to be more touchdowns than I'm seeing come up from spotters/chasers.

Stay safe folks. Thanks Dave for all your work. Big Outbreak. Probably the biggest since Feb 08 IMHO.

Violent Storms Blast Miss. Valley; Heading for Southeast
UPDATED 11 AM CDT, April 24, 2010

Dangerous storms continue to blast the lower Mississippi Valley this morning, before the severe threat explodes across the Tennessee Valley into the Mid-South as the day evolves. Major storms will be capable of destructive tornadoes, gusty winds and damaging hail. Today`s severe risk is the greatest of the season so far.


Tornado Watches area already in effect from eastern Louisiana to central Tennessee and down to the Gulf Coast. This includes Jonesboro, Ark., Memphis and Nashville, Tenn., Jackson, Miss., Birmingham and Mobile, Ala., and Baton Rouge and New Orleans, La.


Severe storms will continue to erupt this morning from eastern Louisiana to eastern Arkansas and across the Deep South. These storms will sweep east into the Tennessee Valley and Southeast later today.


This is a Particularly Dangerous Situation. Strong, destructive and potentially long-lasting tornadoes, damaging hail and winds are likely from the storms, especially from northern Louisiana into eastern Arkansas, western Tennessee, much of Mississippi and Alabama. Residents should keep an eye on developing weather and be prepared to act when tornado watches and warnings are issued.


Cities like Shreveport and Baton Rouge, La., Memphis, Tenn., Jackson, Miss., and Birmingham, Ala., will see the most violent weather while severe thunderstorms are possible farther north into St. Louis, Lexington, Ky., and Cincinnati.
