HYDROLOGIC OUTLOOK
Warning Issue Date: 157 PM CST WED DEC 23 2009
FLOOD POTENTIAL OUTLOOK FOR HEAVY RAIN CHRISTMAS EVE AND
CHRISTMAS MORNING...
MORE HEAVY RAIN IS ANTICIPATED FOR THE CENTRAL TENNESSEE VALLEY
LATER THIS WEEK. A WARM FRONT WILL SURGE INTO THE AREA ON
WEDNESDAY...AND SOME SHOWERS ARE POSSIBLE DURING THE
AFTERNOON...MAINLY WEST OF INTERSTATE 65. RAINFALL AMOUNTS ON
WEDNESDAY ARE NOT EXPECTED TO BE PARTICULARLY HEAVY...BUT AMOUNTS
COULD APPROACH ONE HALF INCH NEAR THE MISSISSIPPI BORDER.
ON CHRISTMAS EVE /THURSDAY/...A STRONG STORM SYSTEM WILL TAKE
SHAPE OVER THE LOWER MISSISSIPPI VALLEY...EVENTUALLY DRAGGING A
COLD FRONT THROUGH THE TENNESSEE VALLEY THURSDAY NIGHT INTO EARLY
CHRISTMAS MORNING. WITH ABUNDANT MOISTURE IN PLACE...HEAVY RAIN
APPEARS INCREASINGLY LIKELY.
ALTHOUGH THE RAIN DOES NOT LOOK TO LAST FOR A PARTICULARLY LONG
PERIOD OF TIME...IT WILL BE QUITE HEAVY WHILE IT LASTS. RAINFALL
TOTALS OF ONE TO THREE INCHES APPEAR POSSIBLE. IF THESE AMOUNTS
DO INDEED OCCUR IN A RELATIVELY SHORT PERIOD OF TIME...FLASH
FLOODING WOULD BE LIKELY...AND WOULD BE FOLLOWED BY RIVER FLOODING
THAT COULD LAST THROUGH THE WEEKEND AFTER CHRISTMAS.
WITH A LARGE NUMBER OF PEOPLE TRAVELING DURING THIS HOLIDAY
PERIOD...HERE ARE SOME IMPORTANT FLOOD REMINDERS. IF YOU SEE
WATER OVER A ROADWAY...DO NOT TAKE A CHANCE...TURN AROUND...DONT
DROWN. ADDITIONALLY...USE EXTRA CAUTION AT NIGHT BECAUSE YOU MAY
COME ACROSS FLOWING WATER OVER A ROAD SOONER THAN YOU CAN REACT.
INTERESTS ACROSS THE TENNESSEE VALLEY SHOULD MONITOR FUTURE
FORECASTS AND BE AWARE OF FUTURE OUTLOOKS AND POSSIBLE FLOOD
WATCHES. FOR ADDITIONAL HYDROLOGIC INFORMATION...VISIT OUR
