...Severe to Extreme Drought Conditions Persist Across Much of East
Central Florida...

Synopsis...

A recent increase in shower and thunderstorm activity across the
area in late May has produced some much needed rainfall for many
areas in east central Florida. From May 22nd through the 25th,
widespread rainfall amounts of 0.50-1.50 inches have fallen across
the region. However, this precipitation has not been enough to
alleviate longer term rainfall deficits. Since the beginning of
October precipitation totals still range around 5 to 12 inches below
normal, and up to 5 to 8 inches below normal since the start of the
year. For many locations this is around 50 to 70 percent of the
normal precipitation for these time periods, with even lower
rainfall amounts across portions of the interior from Orange County
southward through northern Okeechobee County. In fact, for Orlando
it is the 2nd driest start to the year, with a total of 5.11 inches
as of May 26th. These overall much drier than normal conditions has
allowed severe to moderate drought conditions to expand and persist
over much of the region.

As of the Drought Monitor from May 25th, 2017...
*Extreme Drought (D3) conditions exist across extreme southern Lake,
Orange, Osceola, southern Brevard, and western Okeechobee counties.
*Severe Drought (D2) conditions extend from central Lake eastward to
northern Brevard counties, and across Indian River, St. Lucie, and
inland Martin counties.
*Moderate Drought (D1) conditions exist across northern Lake and
Volusia counties.
*Abnormally Dry (D0) conditions extend across coastal Martin County.


Summary of Impacts...

State and Local Impacts: According to the Florida Division of
Forestry, as of May 26th, burn bans are in effect for Volusia, Lake,
Orange, Seminole, Osceola, Brevard, Indian River, St Lucie, Martin
and Okeechobee Counties. Additionally, back on April 11th Governor
Rick Scott issued a state of emergency in Florida due to the recent
increase in wildfires, and continued high potential for additional
brush fires to develop across the state.

The South Florida Water Management District and the St. Johns River
Water Management District have both issued a Water Shortage Warning
for their entire area, which covers all counties in east central
Florida. This encourages residents to reduce water use and
voluntarily conserve water to the maximum extent possible.

Local agricultural and hydrological reports indicate livestock
producers are experiencing increased difficulties due to the
drought. The watering holes and in some cases wells have dried up,
so water has to be hauled or ponds have to be dug deeper. Pastures
are not growing due to the lack of moisture, so producers are
feeding hay, which is hard to find now and generally of poor
quality. There have been increased calls to the USDA about of
livestock deaths. Also, in Brevard county, ranchers have run into
salinity issues due to saltwater intrusion when the ponds are dug
deeper. The saltwater in drinking water can lead to kidney failure
in cattle.

Soil Moisture Conditions: The highest Keetch-Byram Drought Index
(KBDI) values are over Osceola, Orange, and Brevard counties, where
values are 600-700. The KBDI in Volusia, Seminole, Indian River, St.
Lucie and Okeechobee counties is running 500-600. These KBDI values
indicate moderate to severe drought for this time of year.  KBDI
values in northern Lake and Martin counties have fallen below 500
due to recent heavy rainfall there.

Groundwater Conditions: The latest groundwater conditions from the
United States Geological Survey (USGS) as of May 26th indicate
groundwater levels for most observing locations are less than 25
percent of normal for this time of year across east central Florida.
Some locations are even less than 10 percent normal for this time of
year.

River and Stream Flow Conditions: The latest seven day average
streamflow from the USGS as of May 26th indicate increased stream
flow across the area due to recent rainfall. However, there are
several sites across northern portions of east central Florida that
still range from below normal (10 to 24 percent of normal) to a
moderate hydrologic drought (6 to 9 percent of normal).

Fire Danger Hazards: According to the National Interagency Fire
Center, the potential for significant wildland fires continues to be
above normal for all of east central Florida.

Precipitation and Temperature Outlook...

The current Climate Prediction Center`s (CPC) 6-10 and 8-14 day
outlooks, which cover the early part of June, indicate greater
chances for above normal temperatures and for near to above normal
precipitation across the area.

Three Month Outlook (June-July-August): Currently CPC is forecasting
greater odds for above normal temperatures during this period, with
equal chances for above, near, and below normal precipitation. The
wet season, characterized by more daily occurrence of sea breeze
generated showers and storms, typically begins around late May to
early June across east central Florida. As long as there is no
significant delay to the wet season, then rainfall deficits should
gradually improve into the summer.

Next Issuance Date...

The next drought statement will be issued in mid June, or sooner if
significant changes in drought conditions occur.
