HYDROLOGICAL IMPACTS...Some of the well along the southeastern
metro areas and along the west coast metro areas of South Florida
are starting to fall into the lowest 10 to 30 percentile. Rest of
the wells across South Florida are still running near normal
levels at this time.

The most recent underground water reservoir levels in Palm Beach
County were around 15.8 feet which is 0.3 feet below normal.
In Broward County, the levels were around 11.2 feet which is 0.2
feet below normal. In Miami-Dade County, the underground water
reservoirs levels were around 9.1 feet which is 0.8 feet below
normal.

The level of Lake Okeechobee was around 13.7 feet as of April 5
with was around 0.5 feet below the normal level of 14.2 feet. The
level of Fisheating Creek was 1.4 feet as of March 1, around 0.6
feet below the normal level of 2.0 feet for this time of year.

FIRE DANGER IMPACTS...As of April 5, the Keetch-Byram Drought
Index (KBDI) was between 550 to 600 range over Glades, Palm Beach,
and Mainland Monroe Counties, with Rest of South Florida ranging
between 600 to 650 range. This puts most of South Florida in a
very high fire danger level, except for Glades, Palm Beach, and
Mainland Monroe Counties in a high risk of wildfires.

There is also now a Fire Burn Ban in effect for Hendry County
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 approach South Florida from the north
and wash out this weekend. This will allow for some showers maybe
a thunderstorm over South Florida with the best change late this
weekend. Another front will then approach South Florida middle of
next week bringing another low chance of showers to the area.

The Climate Prediction Center`s precipitation outlook for the
next 6 to 14 days calls for an increased likelihood of above-normal
rainfall across South Florida. However, the outlook in general
for rest of April through June 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 rest of April 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 end of April or early May, unless conditions change
before that time. Stay tune to NOAA weather radio and other local
media for further details and updates.
