BULLETIN - IMMEDIATE BROADCAST REQUESTED
SMALL STREAM AND URBAN FLOOD WARNING
NATIONAL WEATHER SERVICE ELKINS WV
930 AM EST SUN DEC 31 1989

THE NATIONAL WEATHER SERVICE IN ELKINS HAS ISSUED A
SMALL STREAM AND URBAN FLOOD WARNING EFFECTIVE UNTIL 1230 PM EST
FOR PEOPLE IN THE FOLLOWING COUNTY...

IN NORTH CENTRAL WEST VIRGINIA
          ...LEWIS

THE WEST VIRGINIA STATE POLICE AND WESTON FIRE DEPARTMENT REPORTS
AN ICE JAM ON POLK CREEK PRODUCED SOME MINOR FLOODING, BUT IS NOW
STARTING TO BREAK AND WATER IS RECEEDING. OTHER SMALL STREAMS ARE
STARTING TO OVERFLOW IN LEWIS COUNTY...MAINLY DUE TO ICE JAMS. MINOR
FLOODING WAS REPORTED ON MURPHYS CREEK.

A FLASH FLOOD WATCH CONTINUES IN EFFECT FOR ALL OF NORTHERN WEST
VIRGINIA TODAY...EXCEPT THE POTOMAC HIGHLANDS AND EASTERN PANHANDLE.

FAVORITE AREAS FOR ICE JAMS TO FORM ARE NEAR BRIDGES, WHERE STREAMS
MAKE SHARP TURNS...SMALL DAM AREAS AND WHERE STREAMS AND CREEKS ENTER
INTO OTHER WATERWAYS THAT MAYBE FROZEN.

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. IF OFFICIALS ASK YOU
TO EVACUATE...DO SO

MARTINSBURG. THE CIVIL DEFENSE IN CUMBERLAND, MARYLAND REPORTS MANY

MOTORIST TRAVELING ACROSS EXTREME EASTERN WEST VIRGINIA AND WESTERN
MARYLAND SHOULD BE ALERT TO ICE ON THE HIGHWAYS...ESPECIALLY IN LOW

ICE...WHICH CAN BE VERY HARD TO SEE SOMETIMES.

WARMER AIR OUT AHEAD OF AN APPROACHING COLD FRONT WILL PUSH
TEMPERATURES UP ABOVE FREEZING BY THIS AFTERNOON.
