THUNDERSTORMS ALONG THE COAST ARE EXPECTED TO MOVE INTO THE AREA

LOCALLY HIGHER AMOUNTS WILL BE POSSIBLE.
WATER LEVELS IN AREA RIVERS ARE CURRENTLY LOW...AND NO RIVER
FLOODING IS EXPECTED AS A RESULT OF THIS RAINFALL. HOWEVER...
ELEVATED FLOWS MAY BE EXPERIENCED ON SOME OF THE FASTER RESPONDING
STREAMS AND RIVERS.
ADDITIONALLY...SOME OF THESE STORMS WILL BE CAPABLE OF PRODUCING
VERY HIGH RAINFALL RATES...UPWARDS OF TWO INCHES PER HOUR.
WIDESPREAD FLASH FLOODING IS NOT EXPECTED. HOWEVER...LOCALIZED
EFFECTS WILL LIKELY ACCOMPANY THE HEAVIEST STORMS. THIS WILL
INCLUDE PONDING OF WATER ON ROADWAYS AND IN AREAS OF POOR
DRAINAGE.
PEOPLE IN THE AFFECTED AREAS SHOULD BE AWARE OF THE FLOODING
POTENTIAL...AND MONITOR THE LATEST INFORMATION FOR ANY
STATEMENTS...WATCHES OR WARNINGS THAT MAY BE ISSUED.
