Drought Information Statement
National Weather Service Miami FL
1133 AM EDT Fri Apr 20 2018

...SEVERE DROUGHT CONDITIONS CONTINUE ACROSS NORTHERN MIAMI-
DADE, WESTERN BROWARD, EASTERN COLLIER, AND EXTREME SOUTHWEST PALM
BEACH COUNTIES...

...MODERATE DROUGHT CONDITIONS CONTINUE OVER REST OF SOUTH
FLORIDA EXCEPT FOR NORTHERN GLADES AND SOUTHERN MAINLAND MONROE
COUNTIES WHERE ABNORMALLY DRY CONDITIONS CONTINUE...

SYNOPSIS...A few cold fronts have moved through South Florida
during the early part of April allowing for rainfall amounts
between half an inch to one inch across the region with some
areas in Palm Beach County seeing between 2 to 4 inches of
rainfall. However, between the cold fronts, very dry air has
worked into South Florida from the north leading to very good
evaporation across the area.

This has allowed the Severe Drought conditions (D2) to continue
over northern Miami-Dade, western Broward, eastern Collier, and
extreme southwest Palm Beach Counties. Moderate Drought conditions
(D1) continue over rest of South Florida, except for northern
Glades County and southern Mainland Monroe County where
Abnormally dry conditions (D0) continue.

Here are some rainfall totals and departures from normal at
several sites across South Florida from November 1st, 2017 to
April 19, 2018. SECONDARY OBSERVATION SITES

HYDROLOGICAL IMPACTS...Most of the wells across South Florida are
currently running near normal levels. The only exception to this
is for the wells over northern metro Miami-Dade and Southern
metro Broward Counties where they are running at the lowest 10 to
30 percentile.

The most recent underground water reservoir levels in Palm Beach
County were around 16 feet which is near normal. In Broward
County, the levels were around 11.1 feet which is 0.1 feet above
normal. In Miami-Dade County, the underground water reservoirs
levels were around 8.8 feet which is 1 foot below normal.

The level of Lake Okeechobee was around 13.3 feet as of April 20
with was around 0.6 feet below the normal level of 13.9 feet. The
level of Fisheating Creek was 1 f00t as of April 20, around 0.2
feet below the normal level of 1.2 feet for this time of year.

FIRE DANGER IMPACTS...As of April 19, the Keetch-Byram Drought
Index (KBDI) was between 600 to 650 range over Miami-Dade,
Collier, and Hendry Counties. Broward and Mainland Monroe Counties
where in the 550 to 600 range, and Glades and Palm Beach Counties
where in the 500 to 600 range. This puts most of South Florida in
a high to very high fire danger risk of wildfires, except for
Glades and Palm Beach Counties where a moderate fire danger risk
of wildfires.

There is also now a Fire Burn Ban in effect for Glades and Hendry
Counties which means that no prescribed fires are allowed in the
county.

RESPONSE/ACTIONS...The South Florida Water Management District
has continued the yearly watering restrictions for South Florida.
For more information on the watering restrictions, please visit
the South Florida Water Management District web site at
http://www.sfwmd.gov/waterwatch.

OUTLOOK...A cold front will be approaching South Florida from the
Gulf of Mexico late this weekend into early next week. This will
allow for an increased chance of showers and thunderstorms over
South Florida this weekend into early next week.

The Climate Prediction Center`s precipitation outlook for the
next 6 to 14 days calls for an increased likelihood of below-normal
rainfall across South Florida. However, the outlook in general
for rest of May through July is for an equal chance of above or
below normal rainfall. Drought conditions are expected to continue
or increase in coverage over South Florida through late this
spring before slowly improving in the early summer time.

There is an above normal potential of significant wildland fires,
especially into May, based on the increased likelihood of dry
conditions continuing into late spring.

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