"Particularly Dangerous Situation" Tornado Watch Just Issued for LA/MS/AL...

A rarely used type of Tornado Watch with "enhanced wording", also known as a 'PDS' or "Particularly Dangerous Situation" Tornado Watch was just issued for portions of Louisiana, Mississippi and Alabama, valid until 8pm CST this evening.

The watch includes the cities of New Orleans, Baton Rouge, Biloxi, Jackson, Mobile, and Hattiesburg.

To my knowledge and with brief research, this is the first time a PDS Tornado Watch has ever been issued on Christmas Day, and I believe during the month of December as well.

Regardless of the trivial/historic nature of the issuance, the most important takeaway is obviously that is a very dangerous situation and folks in and close to the watch area should remain on a high state of alert this afternoon and evening.  Make sure you have a way to receive weather warnings, and pick out the best sheltering option ahead of time so that you can move there quickly if need be.

A line of severe thunderstorms continue to progress Eastward across Louisiana and is entering southwestern Mississippi at this time.  Additional severe storms are likely to develop ahead of the main line this afternoon, and these cells in particular will have high potential for damaging tornadoes.
