HYDROLOGIC OUTLOOK
NATIONAL WEATHER SERVICE ST LOUIS MO
320 PM CST SAT MAR 5 2016

...HEAVY RAINFALL AND FLOODING POSSIBLE NEXT WEEK...

A PROLONGED PERIOD OF HEAVY RAINFALL IS POSSIBLE FOR PARTS OF THE
AREA NEXT WEEK. ALTHOUGH THERE IS STILL UNCERTAINTY IN THE LATEST
MODEL DATA...TUESDAY EVENING THROUGH WEDNESDAY EVENING IS THE
MOST LIKELY PERIOD FOR HEAVY RAIN...AND THE SOUTHEAST HALF OF
MISSOURI AS WELL AS THE SOUTHERN HALF OF ILLINOIS ARE THE MOST
LIKELY AREAS TO RECEIVE THE HEAVIEST RAINFALL AMOUNTS. THIS
INCLUDES THE ST. LOUIS METRO AREA AND ALL COMMUNITIES ALONG AND
SOUTH OF INTERSTATE 44 IN MISSOURI AND INTERSTATE 70 IN ILLINOIS.
WIDESPREAD RAINFALL AMOUNTS OF 4 TO 7 INCHES ARE POSSIBLE...WITH
LOCALLY HIGHER AMOUNTS.

THE SOIL MOISTURE ACROSS THE REGION IS ABOVE AVERAGE...WHILE
LOCAL RIVERS AND CREEKS ARE AT NEAR NORMAL LEVELS AND FLOW. THERE
ALSO REMAINS A LACK OF VEGETATION AS WE TRANSITION OUT OF THE
WINTER SEASON...WHICH INCREASES THE POTENTIAL FOR RUNOFF FROM
EXCESSIVE RAINFALL. THESE ANTECEDENT CONDITIONS...COMBINED WITH
THE POTENTIAL OF VERY HIGH RAINFALL TOTALS...COULD LEAD TO RIVER
FLOODING AS WELL AS FLASH FLOODING IN FLOOD PRONE AREAS.

THOSE WITH INTERESTS ALONG AREA RIVERS SHOULD STAY TUNED TO THE
LATEST WEATHER AND RIVER FORECASTS FROM THE NATIONAL WEATHER
SERVICE IN ST. LOUIS.
