Drought Information Statement
National Weather Service Tampa Bay Area - Ruskin FL
545 PM EDT Thu Apr 20 2017

...Severe Drought persists across west central and southwest
Florida...

SYNOPSIS...
Even with some occasional bouts of rain and thunderstorms over the
last few months, rainfall has run significantly below climatic
normals since October 2016.  Warm dry conditions has caused the
drought to gradually increase in severity across the region.
Overall, rainfall since October 1, 2016 ranges from 4 inches to a
little over 11 inches, which is about 7 to 15 inches below normal,
or 22 to 59 percent of normal.

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

SUMMARY OF IMPACTS...
The Severe Drought area remains unchanged this week and covers
all but Levy, Citrus and northern Sumter counties where
Abnormally Dry conditions still exist.

A Phase One Moderate Water Shortage continues for Sumter county.
Elsewhere across West Central and Southwest Florida the standard
year-round water conservation measures remain in effect at this
time. However, some local governments have adopted water shortage
orders with alternate schedules, so be sure to check with your
city or county to see if any are in effect.

The widespread warm and dry conditions has increased the threat
of wildfires across West Central and Southwest Florida and burn
bans are now in effect for Citrus, Hernando, Pasco, Polk and
Highlands counties. Daily minimum relative humidity values
combined with winds will determine the daily threat level.
Keetch Byram Drought Index values have fluctuated over the past
few weeks and are currently running from near 200 over northern
portions of Levy county to over 650 across most of the central
and southern interior, as well as Southwest Florida. This scale
runs from zero (saturated) to 800 (extreme dryness). Current
values are in the very low to severe range for mid-April. Without
significant rainfall these values will likely continue to increase
over the next few weeks

PRECIPITATION/TEMPERATURE OUTLOOK...
The Climate Prediction Center`s (CPC) 6-10 day and 8-14 day
outlooks call for above normal temperatures and near to below
normal precipitation.

Meanwhile, the long range outlooks from the CPC for the rest of
April, and for the three-month period of April, May, and June,
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 April 28, 2017.
