URGENT - IMMEDIATE BROADCAST REQUESTED

Tornado Watch Number 190

NWS Storm Prediction Center Norman OK

730 AM CDT Wed May 3 2017



The NWS Storm Prediction Center has issued a



* Tornado Watch for portions of

  Southern and Western Louisiana

  Southeast Texas

  Coastal Waters



* Effective this Wednesday morning and afternoon from 730 AM

  until 500 PM CDT.



* Primary threats include...

  A few tornadoes possible

  Scattered large hail and isolated very large hail events to 2.5

    inches in diameter possible

  Scattered damaging wind gusts to 70 mph possible



SUMMARY...Severe thunderstorms will continue to develop and spread

east-northeastward today. Strengthening low-level/deep-layer shear

and an increasingly moist air mass near an inland-developing warm

front will support supercells capable of large hail and a few

tornadoes. Over time, one or more clusters may evolve and move

eastward with a damaging wind risk especially across southern

Louisiana.



The tornado watch area is approximately along and 70 statute miles

north and south of a line from 40 miles south southwest of Lufkin TX

to 50 miles south southeast of Baton Rouge LA. For a complete

depiction of the watch see the associated watch outline update

(WOUS64 KWNS WOU0).



PRECAUTIONARY/PREPAREDNESS ACTIONS...



REMEMBER...A Tornado Watch means conditions are favorable for

tornadoes and 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.



&&



AVIATION...Tornadoes and a few severe thunderstorms with hail

surface and aloft to 2.5 inches. Extreme turbulence and surface wind

gusts to 60 knots. A few cumulonimbi with maximum tops to 600. Mean

storm motion vector 24030.
