The tornado outbreak is beginning to wind down. A threat for tornadoes still exists in parts of Alabama, Florida, and Georgia through the night tonight. Some tornado warnings are still in effect as of 9PM CST.

The tornado threat will continue into the Carolinas tomorrow, with a moderate risk for severe weather issued across parts of eastern South Carolina and North Carolina. Several strong, long-track tornadoes are possible in the threat area.



(Previous diary: PARTICULARLY DANGEROUS SITUATION: Violent Tornado Outbreak In Progress In Deep South)

The Storm Prediction Center has issued a PDS Tornado Watch for parts of Louisiana, Mississippi, and Alabama -- the "PDS" indicating that this is a particularly dangerous situation, enhanced wording used only a few times a year to signal that violent, long-track, long-lived tornadoes are possible within the watch area.

THE NWS STORM PREDICTION CENTER HAS ISSUED A
TORNADO WATCH FOR PORTIONS OF

       SOUTHWESTERN AND WEST-CENTRAL ALABAMA
       EASTERN AND SOUTHEASTERN LOUISIANA
       CENTRAL AND SOUTHERN MISSISSIPPI
       COASTAL WATERS

EFFECTIVE THIS TUESDAY AFTERNOON AND EVENING FROM 1255 PM UNTIL
800 PM CST.

...THIS IS A PARTICULARLY DANGEROUS SITUATION...

DESTRUCTIVE TORNADOES...LARGE HAIL TO 1.5 INCHES IN DIAMETER...
THUNDERSTORM WIND GUSTS TO 75 MPH...AND DANGEROUS LIGHTNING ARE
POSSIBLE IN THESE AREAS.

The watch is in effect right now in anticipation of dangerous supercell thunderstorms forming out ahead of an approaching cold front. The unstable air and strong vertical wind shear will allow these thunderstorms to rotate and produce tornadoes; there is a 70% chance that some of these tornadoes will be violent (EF-2 or stronger) and have tracks dozens of miles long.

The greatest risk is situation along a fairly east-west axis through Louisiana, Mississippi, and Alabama lasting through the night tonight. Bigger cities such as New Orleans LA, Biloxi MS, Mobile AL, and the surrounding areas that are usually protected from large tornadoes by their proximity to the Gulf of Mexico will not have that comfort today. The positioning of the vertical wind shear and instability, which is typically north of these cities during springtime tornado outbreaks, is smack over the I-10 corridor today.

This is a life threatening situation. Please pay attention to watches and warnings for your area, as these thunderstorms (and subsequent tornadoes) will develop quickly. If you live in this area, please let your friends, family, and neighbors know that dangerous weather is possible today.

If the tornadoes start several hours after the posting of this diary, I'll start a separate liveblog diary. I'll try to post the bigger, more urgent updates on my Facebook and Twitter feeds.

3:12 PM PT: Large wedge tornado just moved through downtown Mobile AL. I am safe -- I am home in North Carolina, away from school in Mobile for winter break.

3:23 PM PT: Mobile Fire Department is reporting that there is so much damage in the city that it's overwhelming their capabilities. A high school has been heavily damaged and has a gas leak.

Good news! Earlier, a source at Mobile Fire and Rescue said they were overwhelmed and we reported their comment. Their official Twitter account messaged us and said they're not.

4:38 PM PT: Mobile Infirmary has released a statement saying that the damage is "minor" and that the building still has power. That's good.

4:46 PM PT: The tornado threat is lessening as the storms transition from individual cells to a more linear mode. The tornado threat is far from over, but the risk will slowly transition to damaging winds as the night progresses.

Another tornado outbreak is expected in the Carolinas tomorrow, with a moderate risk issued by the Storm Prediction Center.

More Tagging tips:

A tag is a way to search for this diary. If someone is searching for "Barack Obama," is this a diary they'd be trying to find?

Use a person's full name, without any title. Senator Obama may become President Obama, and Michelle Obama might run for office.

If your diary covers an election or elected official, use election tags, which are generally the state abbreviation followed by the office. CA-01 is the first district House seat. CA-Sen covers both senate races. NY-GOV covers the New York governor's race.

Tags do not compound: that is, "education reform" is a completely different tag from "education". A tag like "reform" alone is probably not meaningful.

Consider if one or more of these tags fits your diary: Civil Rights, Community, Congress, Culture, Economy, Education, Elections, Energy, Environment, Health Care, International, Labor, Law, Media, Meta, National Security, Science, Transportation, or White House. If your diary is specific to a state, consider adding the state (California, Texas, etc). Keep in mind, though, that there are many wonderful and important diaries that don't fit in any of these tags. Don't worry if yours doesn't.
