INCLUDING THE LAKE OKEECHOBEE AREA REMAIN IN A SEVERE DROUGHT STATUS

HYDROLOGIC IMPACTS...
SOME OF THE EAST COAST WELLS ARE STILL FALLING DURING THE LAST HALF
OF MAY AND WAS APPROACHING THE LOWEST 10 PERCENT LEVELS ESPECIALLY
OVER THE FAR WESTERN AREAS...WHILE REST OF THE EAST COAST WELLS ARE
STARTING TO FALL INTO THE 10 TO 30 PERCENT BELOW NORMAL LEVELS.
WELLS ACROSS THE WESTERN AND INTERIOR SECTIONS WERE ALSO STARTING TO
FALL INTO THE LOWEST 10 PERCENT LEVELS...WHILE THE WELLS AROUND LAKE
OKEECHOBEE REMAIN BELOW THE 10 PERCENT LEVEL.
THE UNDERGROUND RESERVOIRS ARE AT ADEQUATE LEVELS OVER THE EASTERN
AREAS OF SOUTH FLORIDA...WHILE THE WESTERN AREAS OF SOUTH FLORIDA
ARE BELOW NORMAL LEVELS. THE LEVEL OF LAKE OKEECHOBEE FELL TO AROUND
9.66 FEET...WHICH IS ABOUT THREE TENTHS LOWER THAN DURING THE MIDDLE
OF THE MONTH. THIS IS ALSO ABOUT 3.5 FEET BELOW NORMAL FOR THIS TIME
OF THE YEAR.
FIRE DANGER IMPACTS...
THE KEETCH-BYRAM DROUGHT INDEX ACROSS SOUTH FLORIDA WAS BETWEEN 550
AND 600...EXCEPT 500 TO 550 IN BROWARD COUNTY AND 450 TO 500 IN PALM
BEACH COUNTY. THIS INDICATES THAT THE FIRE DANGER IS NOW IN THE
SEVERE RANGE FOR MOST OF SOUTH FLORIDA...EXCEPT MODERATE RANGE IN
PALM BEACH COUNTY.
RESPONSE/ACTIONS...
THE SOUTH FLORIDA WATER MANAGEMENT DISTRICT HAS KEPT THE WATER
RESTRICTION AT A PHASE II OVER MOST OF SOUTH FLORIDA. THE ONLY
EXCEPTION IS AROUND THE LAKE OKEECHOBEE AREA WHICH IS IN A PHASE III
WATER RESTRICTION DUE TO THE LOW LEVEL OF LAKE OKEECHOBEE. THIS WILL
LIMIT MOST RESIDENTIAL AND COMMERCIAL WATER USAGE TO TWICE A
WEEK...EXCEPT ONCE A WEEK AROUND THE LAKE OKEECHOBEE AREA.
OUTLOOK...
HIGH PRESSURE WILL REMAIN OVER THE FLORIDA PENINSULA THIS WEEKEND
INTO EARLY NEXT WEEK. THIS WILL KEEP THE WINDS EASTERLY OVER SOUTH
FLORIDA...AND ALLOW FOR ISOLATED TO SCATTERED SHOWERS AND A FEW
THUNDERSTORMS TO AFFECT SOUTH FLORIDA EACH DAY.
THE CLIMATE PREDICTION CENTER'S PRECIPITATION OUTLOOK FOR THE NEXT
14 DAYS IS FOR EQUAL CHANCES OF ABOVE OR BELOW NORMAL RAINFALL. THE
LONGER TERM OUTLOOK THROUGH JULY CONTINUES TO CALL FOR EQUAL CHANCES
OF ABOVE OR BELOW NORMAL RAINFALL.
THE NEXT UPDATE WILL BE AROUND THE MIDDLE OF JUNE UNLESS CONDITIONS
CHANGE BEFORE THEN. STAY TUNED TO NOAA WEATHER RADIO AND OTHER LOCAL
MEDIA FOR FURTHER DETAILS OR UPDATES.
