URGENT - IMMEDIATE BROADCAST REQUESTED
Severe Thunderstorm Watch Number 237
NWS Storm Prediction Center Norman OK
100 PM CDT Mon May 13 2024
The NWS Storm Prediction Center has issued a
* Severe Thunderstorm Watch for portions of
Southwest Louisiana
Southeast Texas
Coastal Waters
* Effective this Monday afternoon and evening from 100 PM until
800 PM CDT.
* Primary threats include...

mph likely

inches in diameter likely
A tornado or two possible
SUMMARY...Clusters of storms are expected to move and develop
eastward into southeast Texas and southwest Louisiana through this
evening. The storm environment favors a mix of supercells capable
of producing very large hail up to 3 inches in diameter, as well as
some upscale growth into clusters/bowing segments with the potential
for damaging winds of 60-80 mph. A tornado or two could occur with
favorable storm/boundary interactions.
The severe thunderstorm watch area is approximately along and 65
statute miles north and south of a line from 50 miles north of
Victoria TX to 25 miles east northeast of Lake Charles LA. For a
complete depiction of the watch see the associated watch outline
update (WOUS64 KWNS WOU7).
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 235...WW 236...
AVIATION...A few severe thunderstorms with hail surface and aloft to
3 inches. Extreme turbulence and surface wind gusts to 70 knots. A
few cumulonimbi with maximum tops to 600. Mean storm motion vector
