SPECIAL WEATHER STATEMENT
NATIONAL WEATHER SERVICE BLACKSBURG VA
246 PM EDT WED JUL 23 1997

...WIDELY SCATTERED THUNDERSTORMS WITH HEAVY DOWNPOURS...

AT 245 PM DOPPLER RADAR IN BLACKSBURG SHOWED THAT WIDELY SCATTERED
THUNDERSTORMS HAD DEVELOPED ACROSS SOUTHEASTERN WEST VIRGINIA...AND
THE BORDERING COUNTIES IN SOUTHWESTERN VIRGINIA. RADAR ESTIMATES OF
RAINFALL AMOUNTS FROM THESE STORMS SHOW RATES OF UP TO TWO
INCHES OF RAIN IN AN HOUR. THESE STORMS WERE MOVING SLOWLY
EASTWARD AT ABOUT 15 MPH...AND WILL CONTINUE TO BRING LOCALLY HEAVY
RAINFALL TO THE AREA THE REST OF THE AFTERNOON.

THIS AMOUNT OF RAINFALL SHOULD NOT CAUSE ANY CREEKS OR SMALL
STREAMS TO COME OUT OF THEIR BANKS...BUT MAY CAUSE SOME FLOODING OF
THE ROADS AND OTHER LOW LYING AREAS.

DO NOT DRIVE YOUR VEHICLE INTO AREAS WHERE WATER COVERS THE
ROADWAY.  THE WATER DEPTH MAY BE TOO GREAT TO ALLOW YOUR CAR TO
CROSS SAFELY.
