Drought Information Statement
National Weather Service Tampa Bay Area - Ruskin FL
623 PM EDT Fri May 19 2017

...Extreme Drought continues across much of the interior
peninsula with Severe Drought from the Tampa Bay area and
south...with Moderate Drought conditions across the nature
coast...

SYNOPSIS...
Locally heavy rain over portions of the nature coast allowed
drought conditions to improve in that region, however generally
below normal rainfall occurred across the remainder of west
central and southwest Florida. Rainfall continues to run
significantly below climatic normals since October 2016 with
amounts ranging from 5 inches to around 13 inches, which is about
8 to nearly 16 inches below normal, or 24 to 63 percent of
normal.

Above normal temperatures and near to below normal rainfall is
generally expected for the next month or so leading into the
Summer rainy season which usually does not start until the second
or third week of June.

SUMMARY OF IMPACTS...
The National Drought Monitor has continued the Extreme drought
much of the interior peninsula including Polk, Hardee, Desoto, and
Highlands counties. Otherwise, Severe drought conditions persist
from southern Pasco county south to Lee county, with moderate
drought across the nature coast.

A Modified Phase One Water Shortage is in effect for the
Southwest Florida Water Management District area. Also, the South
Florida Water Management District and Suwannee River Water
Management District have issued a Water Shortage Warning,
encouraging residents and visitors in the counties the agencies
cover to voluntary conserve water. However, some local governments
have adopted stricter water shortage orders with alternate
schedules, so be sure to check with your city or county to see if
any are in effect.

The hot and dry conditions have increased the threat of wildfires
across West Central and Southwest Florida and burn bans are now
in effect for Levy, Citrus, Hernando, Sumter, Pasco, Pinellas,
Hillsborough, Polk, Manatee, Sarasota, Highlands, and Charlotte,
and Lee counties. Daily minimum relative humidity values combined
with winds will continue to determine the daily threat level.
Countywide average Keetch Byram Drought Index values range from
420 to around 665. However, localized KBDI values vary within
each county due to isolated pockets of heavier rainfall over the
past couple of weeks. The KBDI scale runs from zero (saturated) to
800 (extreme dryness). Current values are in the moderate range
for early to mid May.

The Climate Prediction Center`s (CPC) 6-10 day and 8-14 day
outlooks call for near to above normal temperatures and above
normal precipitation across the southern forecast area with near
to below normal north and central.

Meanwhile, the long range outlooks from the CPC for June, and for
the three-month period of June, July, and August is for better
chances of above normal temperatures to continue with equal
chances of below normal, near normal, or above normal
precipitation.

HYDROLOGIC SUMMARY AND OUTLOOK...
Streamflows across the area are generally below climatological
normals and mostly in the lowest 25th percentile with many in the
lowest tenth percentile. Little change is expected for the next
few weeks without significant rainfall.

NEXT ISSUANCE DATE...
The next statement will be issued by May 26, 2017.
