HYDROLOGIC OUTLOOK
NATIONAL WEATHER SERVICE NEW ORLEANS LA
345 PM CDT MON AUG 8 2016

...HEAVY RAINFALL MAY PRODUCE ELEVATED RIVER LEVELS IN COMING
DAYS...

A VERY MOIST AIR MASS IN PLACE OVER THE EASTERN GULF STATES WILL
BE SLOWLY MOVING WESTWARD THIS WEEK. BY THE MIDDLE OF THE WEEK
DISTURBANCES MOVING OVER THE AREA MAY ACTIVATE THE AIR MASS TO
PRODUCE RATHER LARGE AREAS OF HEAVY RAINFALL. THE RESULT IS LIKELY
TO BE SEVERAL INCHES OF RAINFALL THAT WOULD CAUSE AREA RIVERS AND
STREAMS TO RISE TO ELEVATED...POSSBILY FLOODING LEVELS LATER IN
THE WEEK.

THE CURRENT STATE OF THE RIVERS IN THE GULF DRAINAGE...PASCAGOULA...
PEARL RIVER...LAKE DRAINAGE SYSTEMS ARE AT NOMINAL FLOW LEVELS AT
THIS TIME. THIS ALLOWS FOR SOME CAPACITY FOR THE FIRST FEW INCHES
OF RAINFALL. SHOULD HEAVY RAINS PERSIST OVER A LONG DURATION...OR
IF TORRENTIAL RAINFALL OCCURS OVER A FEW HOURS...THEN RIVER RISES
WILL BE FASTER.

THE AREAS OF GREATER CONCERN AT THIS TIME APPEAR TO BE THE
MISSISSIPPI GULF COAST COUNTIES...THE NEW ORLEANS METRO AREA AND
THE RIVERS THAT DRAIN INTO LAKE PONTCHARTRAIN. TO A LESSER
EXTENT...THE HEAVY RAIN THREAT MAY SPREAD FARTHER WEST LATER IN
THE WEEK TO INCLUDE THE AMITE-COMITE BASIN AND THE STREAMS IN
EAST-CENTRAL LOUISIANA.

STAY TUNED FOR LATER STATEMENTS AND POSSIBLE FLOOD WATCHES THAT
MAY BE POSTED AT A LATER TIME. IN THE MEANTIME...PERSONS NEAR
RIVERS AND STREAMS SHOULD PLAN A COURSE OF ACTION IN THE EVENT A
FLOOD THREAT BECOMES MORE LIKELY OR IMMINENT THROUGHOUT THIS WEEK.
PERSONS MAY WISH TO CLEAR DEBRIS FROM DRAINAGE CULVERTS AND
DITCHES BEFORE HEAVY RAINS ONSET.
