URGENT - IMMEDIATE BROADCAST REQUESTED

Tornado Watch Number 518

NWS Storm Prediction Center Norman OK

SUMMARY...The air mass ahead of an eastward-advancing cold front

will moisten and modestly destabilize this afternoon. Very strong

winds through a deep layer will support the possibility of supercell

storms including a tornado and damaging wind risk. An additional

round of storms, perhaps as a well-organized line, will also move

into the region from the west late this evening and potentially pose

a severe threat.



The tornado watch area is approximately along and 70 statute miles

east and west of a line from 50 miles east northeast of Rocky Mount

NC to 20 miles south of Myrtle Beach SC. For a complete depiction of

the watch see the associated watch outline update (WOUS64 KWNS

WOU8).



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.

surface and aloft to 1 inch. Extreme turbulence and surface wind

gusts to 60 knots. A few cumulonimbi with maximum tops to 400. Mean

storm motion vector 22045.
