HYDROLOGIC OUTLOOK
Warning Issue Date: 424 PM CST THU DEC 10 2009
THE POTENTIAL FOR FLASH FLOODING AND RIVER FLOODING MAY INCREASE...
TWO RAIN PRODUCING SYSTEMS WILL AFFECT THE AREA OVER THE NEXT 72
HOURS. THE FIRST WILL OCCUR ON SATURDAY INTO SATURDAY NIGHT AND THE
SECOND WILL OCCUR FROM MONDAY INTO TUESDAY. EACH SYSTEM HAS THE
POTENTIAL TO PRODUCE AROUND TWO INCHES OF RAINFALL. EVEN THOUGH ALL
OF THE AREA SHOULD SEE HEAVY RAINFALL...THE GREATEST RISK FOR
FLOODING WILL REMAIN ALONG AND NORTH OF INTERSTATE 20. SOIL MOISTURE
OVER THIS AREA IS TWO TO FOUR INCHES ABOVE NORMAL FOR THIS TIME OF
THE YEAR. THE UPPER PEARL RIVER AND TRIBUTARIES IS AT OR NEAR FLOOD
STAGE. THE BIG BLACK RIVER IS NEAR OR ABOVE FLOOD. THE LOWER YAZOO
RIVER AND TRIBUTARIES ARE RUNNING AROUND THREE QUARTERS FLOOD STAGE.
RIVERS AND BAYOUS IN NORTHEAST LOUISIANA AND SOUTHEAST ARKANSAS ARE
ALL BELOW FLOOD STAGE BUT COULD BE SUBJECT TO FLOODING. THE MOST
VULNERABLE AREA FOR FLOODING IS IN NORTHEAST MISSISSIPPI ALONG THE
TOMBIGBEE RIVER SYSTEM WHERE TIBBEE CREEK AND NOXUBEE RIVER ARE JUST
BELOW FLOOD STAGE WHILE THE LUXAPALLILA CREEK IS ABOVE FLOOD STAGE.
THERE IS A POTENTIAL FOR MINOR TO MODERATE RIVER FLOODING TO DEVELOP
OVER ALL AREAS NORTH OF INTERSTATE 20. THERE IS POTENTIAL FOR RIVERS
SOUTH OF INTERSTATE 20 TO SEE SOME MINOR RIVER FLOODING AS WELL. DUE
TO LOW SOIL INFILTRATION RATES...THE POTENTIAL FOR FLASH FLOODING
COULD DEVELOP OVER THE ENTIRE AREA IF HEAVY RAINFALL RATES
MATERIALIZE. STAY TUNED FOR UPDATES AND THE POSSIBLE ISSUANCE OF A
FLOOD WATCH OR FLASH FLOOD WATCH DURING THE NEXT FEW DAYS.
