HYDROLOGIC OUTLOOK
Issue Date: 432 AM CST THU DEC 10 2009
Expiration: 300 PM CST THU DEC 10 2009 ...LOCALLY HEAVY RAIN EXPECTED TO AFFECT SOUTHEAST LOUISIANA AND
SOUTHERN MISSISSIPPI LATE THIS WEEK AND OVER THE WEEKEND...
A SLOW MOVING SURFACE LOW IS EXPECTED TO MOVE ACROSS SOUTHEAST
LOUISIANA AND SOUTHERN MISSISSIPPI OVER THE WEEKEND. AS THE LOW
MOVES NORTHEASTWARD...MODERATE SOUTHEASTERLY WINDS WILL BRING DEEP
GULF MOISTURE INTO THE AREA. WIDESPREAD SHOWERS AND ISOLATED
THUNDERSTORMS EXPECTED TO DEVELOP ACROSS THE REGION FRIDAY AND
CONTINUE TO AFFECT THE AREA THROUGH SUNDAY. A FEW OF THE HEAVIER
STORMS WILL BE CAPABLE OF PRODUCING RAINFALL RATES OF BETWEEN 1.5
AND 2 INCHES PER HOUR.
AVERAGE RAINFALL AMOUNTS OF 1 TO 3 INCHES ARE EXPECTED FOR THE
FRIDAY THROUGH SUNDAY TIME PERIOD. ORDINARILY...THESE RAINFALL
TOTALS WOULD NOT CAUSE PROBLEMS OVER A THREE DAY PERIOD. HOWEVER...
SATURATED COLD GROUND CONDITIONS DUE TO HEAVY RAINFALL EARLIER
THIS WEEK WILL LEAD TO EXCESSIVE RUNOFF AND THE POSSIBILITY OF
FLASH FLOODING. LOCALIZED EFFECTS WILL LIKELY ACCOMPANY THE
HEAVIEST STORMS... INCLUDING PONDING OF WATER ON LOW LYING
ROADWAYS AND IN AREAS OF POOR DRAINAGE.
SEVERAL AREA RIVERS REMAIN NEAR OR JUST ABOVE FLOOD STAGE.
ADDITIONAL RAINFALL AND WATER RUNOFF WILL LEAD TO CONTINUED
ELEVATED STREAM FLOWS AND COULD ALSO RESULT IN ADDITIONAL RIVER
FLOODING.
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.
