WHILE NOT AS MUCH RAIN FELL IN SOUTHEAST FLORIDA AS ACROSS THE
SOUTHWEST FLORIDA GULF COAST AND AROUND LAKE OKEECHOBEE, IT WAS
ENOUGH TO GRADUALLY INCREASE WATER LEVELS ACROSS THE AREA,
PARTICULARLY ACROSS CENTRAL AND SOUTHERN SECTIONS OF MIAMI-DADE
COUNTY WHERE PREVIOUS EXTREME DROUGHT CONDITIONS (D3) HAVE IMPROVED
ONE CATEGORY TO SEVERE DROUGHT CONDITIONS (D2). EXTREME DROUGHT
CONDITIONS REMAIN ACROSS NORTHERN METRO MIAMI-DADE COUNTY AS WELL AS
ALL OF METRO BROWARD COUNTY. PALM BEACH COUNTY REMAINS IN SEVERE
DROUGHT CONDITIONS, EXCEPT FOR AREAS AROUND LAKE OKEECHOBEE AND IN
NORTHWESTERN PORTIONS OF THE COUNTY WHERE MODERATE DROUGHT
CONDITIONS (D1) ARE IN PLACE.

THE EVERGLADES OF MIAMI-DADE AND BROWARD COUNTIES REMAIN IN SEVERE
DROUGHT (D2) CONDITIONS AND MAINLAND MONROE COUNTY IS IN MODERATE
DROUGHT (D1) CONDITIONS.

HYDROLOGICAL IMPACTS...

UNDERGROUND WATER LEVELS MEASURED AT WELLS ACROSS SOUTHEAST FLORIDA
SHOWED SOME IMPROVEMENT, WITH ABOUT HALF OF THE WELLS OBSERVING
WATER LEVELS IN THE LOWEST 10 PERCENT OF SEASONAL HISTORICAL VALUES
AND MOST OF THE REMAINING HALF IN THE LOWEST 10 TO 30 PERCENT OF
SEASONAL HISTORICAL VALUES. IN MID-JULY, ALMOST ALL UNDERGROUND
WATER LEVELS IN MIAMI-DADE AND BROWARD COUNTIES WERE IN THE LOWEST
10 PERCENT RANGE.

GROUNDWATER LEVELS AT THE WATER CONSERVATION AREAS WEST OF THE METRO
AREAS OF SOUTHEAST FLORIDA ALSO SHOWED SOME IMPROVEMENT OVER THE
PAST WEEK, BUT WERE STILL AT 10 TO 25 PERCENT LEVELS COMPARED TO
NORMAL.

THE LEVEL OF LAKE OKEECHOBEE WAS 12.1 FEET AS OF JULY 30TH,
9TH...WHICH WAS ABOUT 1.6 FEET BELOW NORMAL.

FIRE DANGER IMPACTS...

AS OF JULY 30TH...THE KEETCH-BYRAM DROUGHT INDEX (KBDI) WAS 500 TO
549 OVER MIAMI-DADE COUNTY, 450 TO 499 IN BROWARD COUNTY AND 300-399
IN PALM BEACH COUNTY. OVER WESTERN AREAS OF SOUTH FLORIDA INCLUDING
THE GULF COAST, KBDI VALUES IN THE 200-299 RANGE. VALUES ABOVE 450
IN THE SUMMER REFLECT SEVERE DROUGHT CONDITIONS, WITH VALUES BETWEEN
350 AND 450 REFLECTING MODERATE DROUGHT.

RESPONSE/ACTIONS...

THE SOUTH FLORIDA WATER MANAGEMENT DISTRICT CONTINUES TO IMPLEMENT
THE YEAR-ROUND LANDSCAPE IRRIGATION RULES FOR ALL OF SOUTH FLORIDA.
PLEASE VISIT THE SOUTH FLORIDA WATER MANAGEMENT WEB SITE AT
WWW.SFWMD.GOV/WATERWATCH FOR MORE INFORMATION.

OUTLOOK...

LOW PRESSURE ALOFT NEAR FLORIDA WILL KEEP SOUTHWEST WINDS ACROSS THE
AREA THROUGH FRIDAY, FOCUSING MOST OF THE SHOWERS AND THUNDERSTORMS
ACROSS EASTERN AREAS AND FROM LAKE OKEECHOBEE TO PALM BEACH COUNTY.

HIGH PRESSURE ALOFT WILL GRADUALLY BUILD BACK ACROSS SOUTH FLORIDA
THIS WEEKEND INTO EARLY NEXT WEEK, WITH WINDS SHIFTING TO AN EAST TO
SOUTHEAST DIRECTION. THIS WILL FOCUS SHOWERS AND THUNDERSTORMS OVER
THE INTERIOR OF THE PENINSULA, WITH NEAR CLIMATOLOGICALLY-NORMAL
PRECIPITATION CHANCES FOR SOUTH FLORIDA.

THE CLIMATE PREDICTION CENTER`S PRECIPITATION OUTLOOK FOR THE NEXT 6
TO 14 DAYS CALLS FOR AN EQUAL CHANCE OF ABOVE OR BELOW NORMAL
RAINFALL ACROSS SOUTH FLORIDA.

THE NEXT UPDATE WILL BE IN EARLY OR MID-AUGUST...UNLESS CONDITIONS
CHANGE BEFORE THAT TIME. STAY TUNED TO NOAA WEATHER RADIO AND OTHER
LOCAL MEDIA FOR FURTHER DETAILS AND UPDATES.
