...Extreme drought conditions developed over northern Glades County...

...Severe drought conditions continue over most of the western
areas of South Florida...

SYNOPSIS...High pressure has been mostly in control of South
Florida this week allowing for the sea breezes to develop and push
inland each day. This has allowed for scattered showers and a few
thunderstorms to develop along the sea breezes each afternoon.
Rainfall amounts range from tenth to half an inch along the metro
areas to 1 to 2 inches over the interior areas. The only area
that did not see much rainfall was over Glades County where only
tenth to quarter of an inch occurred. Therefore, extreme drought
conditions (D3) has developed over northern Glades County, while
severe drought conditions (D2) continue over the western areas of
South Florida and moderate drought conditions (D1) continues over
Mainland Monroe County.

Here are some rainfall totals and departures from normal at
several sites across South Florida from OCT 1, 2016 to May 4,
2017.

HYDROLOGICAL IMPACTS...

The wells over the Lake Okeechobee region and the west coast of
South Florida are still running at 10 to 25 percent of normal
levels, while the wells over the east coast metro areas are
running near to above average levels

The underground water reservoirs in Palm Beach County were around
16.1 feet which was 0.4 feet above normal. In Broward County, the
reservoirs were around 11.8 feet which was 0.8 feet above normal.
In Miami-Dade County, the underground water reservoirs were
around 8.8 feet which was 0.9 feet below normal.

The level of Lake Okeechobee was around 11.6 feet as of May 5,
which was around 1.9 feet below the normal level of 13.5 feet for
this time of year. The level of Fisheating Creek was 0.3 feet as
of May 5, which was 0.9 feet below the normal level of 1.2
feet for this time of year.

South Florida Water Management District has kept S-135, G-36,
S-127, AND S-131 locks closed on Lake Okeechobee due to the low
level of Lake Okeechobee. S-193 lock on Lake Okeechobee will be
reduced to Saturday and Sundays between 5:30 AM and 10:30 PM for
operation.


FIRE DANGER IMPACTS...

As of May 4, the Keetch-Byram Drought Index (KBDI) was 500 to 550
over the western areas of South Florida , 450 to 500 over Mainland
Monroe County, 400 to 450 over Miami-Dade County, and less than
400 over Broward and Palm Beach Counties. This puts the western
areas in a moderate fire danger, while the eastern areas in a low
risk. There is also a state of emergency for the fire danger for
all of Florida from the Governor of Florida.

RESPONSE/ACTIONS...

The South Florida Water Management District has issued a water
shortage warning for South Florida, and they are asking all
visitors and residents of South Florida to heighten water
conservation efforts. 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 in control of South Florida weather this
weekend into early next week keeping the weather dry.

The Climate Prediction Center`s Precipitation outlook for the
next 8 to 14 days calls for below normal rainfall across South
Florida. The long term outlook for May through July is for an
equal chance of above or below normal rainfall across South
Florida.

The next update on the drought conditions for South Florida will be
around the middle of May, unless conditions change before that
time. Stay tune to NOAA weather radio and other local media for
further details and updates.
