SPECIAL WEATHER STATEMENT - SEVERE WEATHER POTENTIAL OUTLOOK
NATIONAL WEATHER SERVICE PITTSBURGH PA
528 AM EDT MON JUN 2 1997

...SEVERE THUNDERSTORMS UNLIKELY TODAY...
...BUT RAINS HEAVY ENOUGH FOR FLOODING ARE POSSIBLE TODAY IN THE
   MOUNTAINS OF NORTHERN WEST VIRGINIA AND GARRETT COUNTY MARYLAND...

THE CHANCES OF THUNDERSTORMS DEVELOPING WILL BE LIMITED TODAY AND ONLY
SLIGHTLY MORE FAVORABLE TONIGHT. THOSE THUNDERSTORMS THAT DO DEVELOP
SHOULD NOT SHOW SEVERE CHARACTERISTICS EXCEPT FOR THE POTENTIAL FOR
HEAVY LOCALIZED RAINFALL.

OF MORE CONCERN IS THE CHANCE OF HEAVY RAIN RESULTING IN FLOODING. SOIL
CONDITIONS ARE SUCH THAT FLOODING CAN OCCUR IN POOR DRAINAGE AREAS AND
ALONG SMALL STREAMS...IF RAIN AMOUNTS EXCEED 1.5 INCHES IN UNDER 3 HOURS
OR EXCEED 2.5 INCHES IN LESS THAN 6 HOURS.

EASTERLY WINDS OFF THE ATLANTIC OCEAN WILL BRING MOISTURE INTO THE
MOUNTAIN AREAS. THE LIFTING EFFECTS OF THE MOUNTAINS WILL KEEP THE
HEAVIEST RAINFALL OVER THE RIDGES AND EAST.

SKYWARN ACTIVATION MAY BE NECESSARY LATER TODAY IF THE HEAVY RAINS
DEVELOP.
