METRO AND SURROUNDING AREAS...

AT 845 PM...NATIONAL WEATHER SERVICE RADAR INDICATED NUMEROUS
THUNDERSTORMS ACROSS EASTERN YORK...SOUTHERN MECKLENBURG...AND UNION
COUNTIES. THE MAIN THREAT FROM THESE STORMS WILL BE VERY HEAVY
RAINFALL...AND AS MUCH AS 2 INCHES OF RAIN IN AN HOUR IS POSSIBLE
WITH THE STRONGEST STORMS. THIS AMOUNT OF RAIN WILL LIKELY PRODUCE
FLOODING OF LOW LYING AND POOR DRAINAGE AREAS...ESPECIALLY IN MONROE

OCCUR ON MAJOR HIGHWAYS ACROSS THE AREA...AS WELL AS SIDE ROADS. IN
ADDITION TO TORRENTIAL RAINFALL...GUSTY WINDS AND FREQUENT CLOUD TO
GROUND LIGHTNING CAN ALSO BE EXPECTED.

DO NOT DRIVE YOUR VEHICLE INTO AREAS WHERE THE WATER COVERS THE
ROADWAY. THE WATER DEPTH MAY BE TOO GREAT TO ALLOW YOUR CAR TO CROSS
SAFELY. VEHICLES CAUGHT IN RISING WATER SHOULD BE ABANDONED QUICKLY.
MOVE TO HIGHER GROUND.
