...Drought Conditions Continue to Worsen Across East Central
Florida...

Synopsis...

Persistent moderate to heavy rainfall produced around 2 to 5 inches
of precipitation along the southern Treasure Coast early on the 23rd
of April. This led to some relief of drought conditions across
coastal sections of Martin and southern St. Lucie Counties. However,
well below normal rainfall has continued across much of the rest of
east central Florida, leading to worsening drought conditions into
early May. Currently, rainfall deficits since the beginning of
October are around 6 to 12 inches below normal across the region,
and up to 4 to 8 inches below normal since the start of the new
year. For many locations this is around half of the normal
precipitation for these time periods.

The Drought Monitor from May 4th, 2017 indicates...
*Extreme Drought (D3) conditions now exist across extreme southern
Osceola and western Okeechobee counties.
*Severe Drought (D2) conditions extend from southern Lake, Orange,
Seminole and southern Brevard counties southward through central
Osceola, Indian River, St. Lucie, and inland Martin counties.
*Moderate Drought (D1) conditions exist across northern Lake,
Volusia, and coastal northern Brevard 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 2nd, burn bans are in effect for Volusia, Lake,
Orange, Seminole, Osceola, Brevard, Indian River, St Lucie 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.

Local agricultural and hydrological reports indicate livestock
producers are experiencing difficulties in finding grass suitable
for grazing and are going out of state to find hay for cattle. The
prolonged dry period has also resulted in ponds drying up, leading
to livestock water tanks needing to be manually filled.

Also, the South Florida Water Management District has issued a Water
Shortage Warning, encouraging residents in the counties the agency
covers to voluntary conserve water use. In east central Florida this
covers portions of Orange, Osceola, Okeechobee, St. Lucie, and
Martin counties.

Soil Moisture Conditions: The highest Keetch-Byram Drought Index
(KBDI) values are over the interior sections of east central
Florida. KBDI values are running 600-700 in Seminole, Orange and
Osceola counties, and 500-600 in Lake, Okeechobee, Brevard, Indian
River, and St. Lucie counties. Recent heavy rainfall has allowed
values to fall to between 400-500 in Volusia and Martin counties.
These KBDI values are indicative of moderate to severe drought for
this time of year.

Groundwater Conditions: The latest groundwater conditions from the
United States Geological Survey (USGS) as of May 3rd indicate
groundwater levels for most observing locations are less than 25
percent of normal for this time of year across east central Florida.
These levels are below to much below normal for this time of year.

River and Stream Flow Conditions: The latest seven day average
streamflow from the USGS as of May 3rd indicate varying streamflow
levels across the region. However, the majority are reporting levels
below to much below normal for this time of year, or less than 25
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 Climate Prediction Center`s (CPC) 6-10 and 8-14 day outlooks,
which cover the period through mid May, indicate greater chances for
above normal temperatures and for below normal precipitation
persisting across the area.

Three Month Outlook (May-June-July): 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
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 late May, or sooner if
significant changes in drought conditions occur.
