DAMAGING WINDS CAN BE EXPECTED ALONG WITH ISOLATED TORNADOES.

YOU WOULD DO IN CASE OF SEVERE WEATHER AHEAD OF TIME AND THEN LISTEN
TO RADIO...TELEVISION...AND NOAA WEATHER RADIO FOR POSSIBLE
WATCHES...WARNINGS...AND STATEMENTS THROUGH TONIGHT.

MOVES SOUTHEASTWARD THROUGH THE REGION.

ANOTHER FRONT APPROACHES.
