   URGENT - IMMEDIATE BROADCAST REQUESTED
   Severe Thunderstorm Watch Number 339
   NWS Storm Prediction Center Norman OK
   505 PM CDT Tue May 27 2025

   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of 
     Southwest Alabama
     Far Western Florida Pahandle
     Extreme Eastern Louisiana
     Southeast Mississippi
     Coastal Waters

   * Effective this Tuesday afternoon and evening from 505 PM until
     1100 PM CDT.

   * Primary threats include...
     Scattered large hail and isolated very large hail events to 2
       inches in diameter possible
     Scattered damaging wind gusts to 70 mph possible

   SUMMARY...Thunderstorms are developing across southeast Mississippi
   and adjacent far eastern Louisiana, and the environment across the
   region supports strong to severe storms capable of large hail and
   damaging gusts. These thunderstorms will likely persist for at least
   the next several hours, with some chance for upscale growth into a
   convective line as they move into more of southwest/coastal Alabama
   and the far western Florida Panhandle.

   The severe thunderstorm watch area is approximately along and 80
   statute miles east and west of a line from 50 miles east northeast
   of Meridian MS to 35 miles west of Mobile AL. For a complete
   depiction of the watch see the associated watch outline update
   (WOUS64 KWNS WOU9).

   PRECAUTIONARY/PREPAREDNESS ACTIONS...

   REMEMBER...A Severe Thunderstorm Watch means conditions are
   favorable for severe thunderstorms in and close to the watch area.
   Persons in these areas should be on the lookout for threatening
   weather conditions and listen for later statements and possible
   warnings. Severe thunderstorms can and occasionally do produce
   tornadoes.

   OTHER WATCH INFORMATION...CONTINUE...WW 337...WW 338...

   AVIATION...A few severe thunderstorms with hail surface and aloft to
   2 inches. Extreme turbulence and surface wind gusts to 60 knots. A
   few cumulonimbi with maximum tops to 500. Mean storm motion vector

For each watch, probabilities for particular events inside the watch
(listed above in each table) are determined by the issuing forecaster.
The “Low” category contains probability values ranging from less than 2%
to 20% (EF2-EF5 tornadoes), less than 5% to 20% (all other probabilities),
“Moderate” from 30% to 60%, and “High” from 70% to greater than 95%.
High values are bolded and lighter in color to provide awareness of
an increased threat for a particular event.
