SPRING FLOOD OUTLOOK
NATIONAL WEATHER SERVICE HOUSTON/GALVESTON, TX
625 AM CST FRI MAR 5 2010
...SPRING FLOOD OUTLOOK FOR SOUTHEASTERN PORTIONS OF TEXAS INCLUDING
THE LOWER TRINITY, SAN JACINTO, LOWER BRAZOS, LOWER COLORADO, AND
LAVACA-NAVIDAD RIVER BASINS...
SPRING POTENTIAL FOR FLOODING IN THIS AREA IS ABOVE AVERAGE AT THIS
TIME WITH HIGHER POTENTIALS ACROSS THE EASTERN BASINS OF THE AREA.
MOST OF THESE BASINS HAVE RECEIVED ABOVE AVERAGE RAINFALL SINCE THE
BEGINNING OF FALL 2009 PRECIPITATION SINCE THE BEGINNING OF THE
WATER YEAR, OCTOBER 1 2009, IS AVERAGE TO JUST ABOVE AVERAGE ACROSS
MOST OF THE AREA WITH WHICH HAS BEEN A REPRIEVE FROM THE DRIER
CONDITIONS THIS TIME LAST YEAR. HIGHER AMOUNTS HAVE FALLEN ALONG THE
GULF COASTAL BASINS. THIS HAS ELIMINATED THE DROUGHT CONDITIONS
EXPERIENCED THIS TIME LAST YEAR. THE SEASONAL DROUGHT OUTLOOK FOR
THE NEXT 60 DAYS FORECASTS CONTINUED FAVORABLE CONDITIONS.
STREAMFLOW CONDITIONS ACROSS THIS REGION ARE NEAR NORMAL TO WELL ABOVE NORMAL
BASEFLOW, WHICH IS GENERALLY TYPICAL FOR THIS TIME OF YEAR. MOST AREA
RESERVOIRS ARE ABOVE OR APPROACHING CONSERVATION LEVELS, SOMETHING UNSEEN FOR
THE PAST FEW YEARS.
SOIL MOISTURE IS VERY WET FOR THESE BASINS WHICH WILL ENHANCE THE
RUNOFF POTENTIAL FROM TYPICAL HEAVY SPRING RAINS. THEREFORE, THE
POTENTIAL FOR RIVER FLOODING REMAINS HIGH THIS SPRING.
EXTENDED OUTLOOKS CALL FOR 33 TO 50 PERCENT CHANCE OF ABOVE AVERAGE PRECIPITATIO
N
AND 33-40 PERCENT CHANCE OF BELOW AVERAGE TEMPERATURE FOR THE NEXT 90 DAYS.
