SPECIAL WEATHER STATEMENT
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
1120 AM EDT MON JUL 7 2003

...LOCALLY HEAVY RAINFALL POSSIBLE IN THE WESTERN CAROLINAS AND
NORTHEAST GEORGIA THIS AFTERNOON AND EVENING...

AN UPPER LEVEL DISTURBANCE WILL CROSS THE SOUTHERN APPALACHIANS FROM
THE WEST THIS AFTERNOON...INTERACTING WITH A MOIST AIRMASS IN PLACE
ACROSS THE REGION TO PRODUCE SCATTERED SHOWERS AND THUNDERSTORMS.
THE THUNDERSTORMS ARE EXPECTED TO BE MOST NUMEROUS FROM THE NORTHERN
FOOTHILLS TO THE NORTHWEST PIEDMONT OF NORTH CAROLINA...GENERALLY
ALONG AND NORTH OF THE INTERSTATE 40 CORRIDOR.

THE ABUNDANT MOISTURE IN THE ATMOSPHERE...COMBINED WITH THE SLOW
EASTWARD PROGRESSION OF ANY STORMS THAT DEVELOP...WILL CREATE THE
POTENTIAL FOR LOCALLY HEAVY RAINFALL WITH ANY OF THESE
THUNDERSTORMS. ANY THUNDERSTORMS THAT DEVELOP THIS AFTERNOON WILL
HAVE THE POTENTIAL TO PRODUCE RAINFALL AT THE RATE OF TWO INCHES PER
HOUR. IF SEVERAL THUNDERSTORMS REPEATEDLY AFFECT THE SAME
LOCATION...THEN FLASH FLOODING COULD QUICKLY DEVELOP.

THE NATIONAL WEATHER SERVICE WILL CLOSELY MONITOR THE SITUATION THIS
AFTERNOON IN CASE ANY FLOOD WATCHES OR FLASH FLOOD WARNINGS BECOME
NECESSARY. STAY TUNED TO NOAA WEATHER RADIO OR YOUR FAVORITE MEDIA
OUTLET FOR THE VERY LATEST.
