WITH MOST OF THE RAINFALL FALLING OVER NORTHERN AREAS OF SOUTH
FLORIDA DURING THE LAST HALF OF JULY INTO EARLY AUGUST, DROUGHT
CONDITIONS HAVE IMPROVED OVER PALM BEACH COUNTY TO MODERATE
DROUGHT CONDITIONS (D1). THE EVERGLADES OF SOUTH FLORIDA HAS
DEGRADED TO EXTREME DROUGHT CONDITIONS (D3) DUE TO THE LACK OF
RAINFALL AND THE WATER LEVELS BEING VERY LOW. WHILE NOT MUCH RAIN
FELL OVER METRO BROWARD COUNTY, IT WAS ENOUGH TO GRADUALLY
INCREASE WATER LEVELS ACROSS THE AREA LEADING TO AN IMPROVEMENT IN
THE DROUGHT CONDITIONS TO SEVERE DROUGHT CONDITION (D2). METRO
MIAMI-DADE COUNTY REMAIN IN A SEVERE DROUGHT CONDITION (D2).

HYDROLOGICAL IMPACTS...

WELLS OVER PALM BEACH COUNTY REMAIN IN THE LOWEST 10 TO 30 PERCENT
RANGE, EXCEPT FOR THE METRO WELLS WHERE THEY ARE NEAR NORMAL
LEVELS. THE WELLS OVER METRO AREAS OF BROWARD AND MIAMI-DADE
COUNTY ARE ALSO IN THE LOWEST 10 TO 30 PERCENT RANGE, AND THE
WELLS OVER THE EVERGLADES AREA ARE IN THE LOWEST 10 PERCENT RANGE.
THE WELLS OVER THE WESTERN AREAS OF SOUTH FLORIDA ARE RUNNING NEAR
NORMAL LEVELS, EXCEPT FOR A FEW WELLS OVER THE WEST COAST METRO
AREAS WHERE THEY ARE IN THE LOWEST 10 TO 30 PERCENT RANGE.

THE UNDERGROUND WATER RESERVOIRS IN PALM BEACH COUNTY WERE AROUND
15.7 FEET WHICH WAS 1 FOOT BELOW NORMAL. IN BROWARD COUNTY...THE
RESERVOIRS WERE AROUND 12 FEET WHICH WAS NEAR NORMAL. IN MIAMI
DADE COUNTY...THE UNDERGROUND WATER RESERVOIRS WERE AROUND 8.7
FEET...WHICH IS 0.8 FEET BELOW NORMAL.

THE LEVEL OF LAKE OKEECHOBEE WAS AROUND 12.6 FEET AS OF AUGUST
20TH...WHICH WAS ABOUT 1.5 FEET BELOW THE NORMAL LEVEL OF 14.1
FEET. THE LEVEL OF FISHEATING CREEK WAS 6.6 FEET AS OF AUGUST
20TH...WHICH WAS AROUND 1.6 FEET ABOVE THE NORMAL LEVEL OF 5 FEET
FOR THIS TIME OF YEAR.

FIRE DANGER IMPACTS...

AS OF AUGUST 20TH...THE KEETCH-BYRAM DROUGHT INDEX (KBDI) WAS LESS
THAN 300 OVER THE NORTHERN AREAS OF SOUTH FLORIDA, AND 450 TO 500
OVER THE SOUTHERN AREAS OF SOUTH FLORIDA. THIS PUTS THE THE
SOUTHERN AREAS OF SOUTH FLORIDA IN A MODERATE TO HIGH RISK OF
WILDFIRES WITH THE NORTHERN AREAS OF SOUTH FLORIDA IN A LOW RISK
OF WILDFIRES.

RESPONSE/ACTIONS...

THE SOUTH FLORIDA WATER MANAGEMENT DISTRICT HAS CONTINUED THE
YEARLY WATER RESTRICTION FOR ALL OF SOUTH FLORIDA. FOR MORE
INFORMATION ON THE WATER SHORTAGE CONDITIONS ...PLEASE VISIT THE
SOUTH FLORIDA WATER MANAGEMENT WEB SITE AT WWW.SFWMD.GOV/WATERWATCH.

OUTLOOK...

HIGH PRESSURE WILL BE MOSTLY IN CONTROL OF SOUTH FLORIDA WEATHER
THIS WEEKEND INTO EARLY NEXT WEEK ALLOWING FOR AN EASTERLY WIND FLOW
OVER THE AREA. THIS WILL FOCUS THE SHOWERS AND THUNDERSTORMS OVER
THE INTERIOR AND WESTERN AREAS OF SOUTH FLORIDA.

THE CLIMATE PREDICTION CENTER`S PRECIPITATION OUTLOOK FOR THE NEXT 8
TO 14 DAYS CALLS FOR AN EQUAL CHANCE OF ABOVE OR BELOW NORMAL RAINFALL
ACROSS SOUTH FLORIDA. THE LONG TERM OUTLOOK FOR SEPTEMBER THROUGH
NOVEMBER IS ALSO FOR AN EQUAL CHANCE OF ABOVE OR BELOW NORMAL
RAINFALL ACROSS SOUTH FLORIDA.

THE NEXT UPDATE WILL BE AROUND THE END OF AUGUST TO EARLY
SEPTEMBER...UNLESS CONDITIONS CHANGE BEFORE THAT TIME. STAY TUNED
TO NOAA WEATHER RADIO AND OTHER LOCAL MEDIA FOR FURTHER DETAILS
AND UPDATES.
