HYDROLOGIC OUTLOOK
Warning Issue Date: 547 AM CST SUN DEC 06 2009
FLOOD POTENTIAL OUTLOOK...
A POWERFUL STORM SYSTEM WILL MOVE FROM THE ROCKIES TO THE GREAT
LAKES DURING TUESDAY AND WEDNESDAY. DEEP MOISTURE MOVING INLAND
EAST OF THIS STORM...AND A FRONTAL BOUNDARY PRESENT ACROSS THE
TENNESSEE VALLEY...WILL SET THE STAGE FOR A RAIN EVENT. AT THIS
TIME...RAINFALL AMOUNTS FOR TUESDAY AND TUESDAY NIGHT WILL RANGE
UPWARDS OF TWO INCHES ACROSS PARTS OF THE AREA. THIS COULD RESULT IN
FLOODING...ALONG WITH AREA STREAM AND RIVER LEVEL RISES.
LOCATIONS GENERALLY WEST OF THE INTERSTATE 65 CORRIDOR WILL BE MOST
SUSCEPTIBLE TO RUNOFF FLOODING FROM EXCESSIVE RAINFALL. MOST OF THE
DECIDUOUS VEGETATION THAT NORMALLY HELPS TO MINIMIZE RUNOFF IS NOW
DORMANT...THUS LIGHTER AMOUNTS OF RAIN COULD BECOME MORE OF A
THREAT. RIVER AND STREAM RISES WILL BE MORE LIKELY ACROSS THE ENTIRE
AREA TUESDAY NIGHT AND WEDNESDAY.
RESIDENTS OF THE TENNESSEE VALLEY SHOULD STAY ALERT FOR FUTURE
OUTLOOKS OR POSSIBLE FLASH FLOOD WATCHES AND WARNINGS. KNOW WHAT TO
DO IF A WARNING IS ISSUED.
