600 AM EDT FRI AUG 24 1990

...PERIODS OF HEAVY RAIN LIKELY TO CONTINUE ACROSS WESTERN AND CENTRAL
LONG ISLAND..NEW YORK CITY AND EASTERN NEW JERSEY THIS MORNING...

VERY WARM AND HUMID TROPICAL AIR MOVING UP FROM THE SOUTH ABOVE THE
SURFACE IS CLASHING WITH LOW PRESSURE PUSHING ACROSS FROM THE WEST AND
THE RESULT IS PERIODS OF HEAVY RAIN OVER AREAS FROM EASTERN NEW JERSEY
TO CENTRAL LONG ISLAND.

RADAR IN NEW YORK CITY AT 6 AM SHOWED AREAS OF HEAVY RAIN MOVING UP
FROM THE SOUTH ACROSS EASTERN NEW JERSEY AND LONG ISLAND OVER THE AREA
FROM ISLIP WESTWARD. GREATER THAN AN INCH OF RAIN WAS DUMPED IN MANY
OF THESE AREAS OVERNIGHT AND MORE RAIN WILL CONTINUE TO POUR DOWN
DURING THIS MORNING. THIS WILL CONTINUE TO RESULT IN SOME LOCAL ROAD

HAZARDOUS TRAVELING CONDITIONS AND SHOULD NOT ATTEMPT TO DRIVE THROUGH

THIS PATTERN SHOWS LITTLE SIGNS OF SHIFTING AND THROUGH THIS MORNING
IT APPEARS PROBABLE THAT THESE HEAVILY HIT AREAS WILL CONTINUE TO
RECEIVE OCCASIONAL PERIODS OF HEAVY RAIN. THIS WILL ALSO RESULT IN
MORE FLOODING PROBLEMS ON LOCAL ROADWAYS AND POOR DRAINAGE AREAS.

MOTOyRISTS ARE ADVISED TO DRIVE WITH CAUTION AND TO LISTEN FOR ANY
