URGENT - IMMEDIATE BROADCAST REQUESTED

Tornado Watch Number 111

NWS Storm Prediction Center Norman OK

450 PM CDT Sun Apr 2 2017



The NWS Storm Prediction Center has issued a



* Tornado Watch for portions of

  Southeastern Louisiana

  Central and southern Mississippi



* Effective this Sunday afternoon and Monday morning from 450 PM

  until 200 AM CDT.



* Primary threats include...

  A few tornadoes likely with a couple intense tornadoes possible

  Scattered damaging wind gusts to 70 mph possible

  Isolated very large hail events to 2 inches in diameter possible



SUMMARY...The tornado and organized severe-wind threat will increase

through the remainder of this evening as a warm front moves across

the region ahead of a line of thunderstorms initially in Louisiana.

That line will sweep into the watch area, absorbing nearby

supercells and generating its own circulations, with embedded

tornadoes possible.  A few separate supercells also should occur

ahead of the line, offering tornadoes and isolated large hail.  See

SPC mesoscale discussion 405 for initial meteorological reasoning.



The tornado watch area is approximately along and 65 statute miles

east and west of a line from 30 miles east southeast of Baton Rouge

LA to 40 miles east northeast of Greenwood MS. For a complete

depiction of the watch see the associated watch outline update

(WOUS64 KWNS WOU1).



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.
