...DROUGHT IMPROVEMENTS...

.SYNOPSIS...

.Drought intensity and extent:
Over the past month, there has been widespread drought improvement
across much of southeast Texas due to a shift in weather pattern.
The change to a wetter pattern has brought scattered showers and
thunderstorm each day across most of southeast Texas. Currently,
only severe drought (D2) conditions persist in portions of
Wharton, Colorado, Austin, and Washington counties. Meanwhile, the
rest of the region is either experiencing abnormal dry (D0),
moderate drought (D1), or normal conditions. As a result to the
continued improvements, this will be the last drought impact
statement for this event.

.SUMMARY OF IMPACTS...

.Agricultural Impacts...

No new impacts.

.Previous Agricultural Impacts...

Several agricultural impacts have been reported since the
previous update. These impacts include but are not limited to
no Highland Lakes water will be available to LCRA interruptible
water customers in the Gulf Coast and water conservation notices
across local communities in southeast Texas.

Soil moisture conditions continue to worsen due to a lack of rain
in the Texas` Coastal Bend. Most field crops have been showing
signs of stress, especially in lighter soils. Pasture conditions
are dry and available forage is poor quality. Livestock are being
fed hay and protein supplements as needed. Cattle are in fair to
good condition but are losing condition daily from lack of
forage,especially the spring calves. Many producers are pulling
fall calves earlier than normal due to declining conditions.

.Fire Impacts and the Keetch-Byram Drought Index:

A burn ban remains in effect for Fort Bend, Austin, Washington,
Jackson, and Chambers counties.

KBDI is an index used to determine forest fire potential, which
is based on a daily water balance considering precipitation and
soil moisture. The KBDI can range from 0 to 800, where a value of
0 represents no moisture depletion, and 800 would be
representative of absolutely dry conditions. A KBDI between 600
and 800 is often associated with severe drought and increased
wildfire potential. The following table lists the KBDI for
counties across the region as of September 9th that are
experiencing drought conditions.

KBDI 0-200... Fort Bend, Matagorda, Jackson
KBDI 200-300... Burleson, Liberty, Montgomery, Harris, Waller,
Galveston, Brazoria, Wharton
KBDI 300-400... Chambers, Austin, Colorado, Brazos, Grimes,
Walker, San Jacinto, Trinity, Polk
KBDI 400-500... Houston, Madison, Washington
KBDI 500-600... None
KBDI 600-700... None
KBDI 700-800... None

.CLIMATE SUMMARY...

Continued showers and thunderstorms over the past couple of weeks
has led to rain totals of generally 6 to 10+ inches with isolated
amounts up to 15+ inches. This is about 4 to 8+ inches above
normal for the month. With the increase in precipitation, mean
temperatures across southeast Texas have been running a couple of
degrees below normal over the past week.


Below is a list of the counties with their highest classification
as designated by the U.S. Drought Monitor as of September 8th.

None...Montgomery
D-0... Houston, Trinity, Polk, San Jacinto, Walker, Madison,
Liberty
D-1... Burleson, Brazos, Grimes, Waller, Harris, Chambers,
Brazoria, Galveston, Fort Bend, Matagorda, Jackson
D-2... Wharton, Colorado, Austin, Washington
D-3... None
D-4... None

A brief description of the U.S. Drought Monitor classifications
currently ongoing in southeast Texas can be found below:

D3...Extreme Drought - Soil has large cracks and soil moisture is
very low.
D2...Severe Drought - Crop or pasture losses likely.
Some water shortages common and some water restrictions imposed.
D1...Moderate Drought - Some damage to crops and pastures.
Reservoirs or wells low. Voluntary water restrictions imposed.
D0...Abnormally Dry - Short term dryness. Plant growth slows.
Minor water deficits.

The next drought monitor update will be issued on September 15th.

.LOCAL DROUGHT OUTLOOK...

.Precipitation/Temperature Outlook...

The local forecast over the next week as of Friday, September
9th is that drier air will dominant the forecast but scattered
afternoon showers and thunderstorms are still possible. The only
exception is on Sunday with increased pops from an upper level
low and subsequent shortwave. Temperatures will be near or
slightly above normal.

For the month of September, the Climate Prediction Center (CPC)
is calling for equal chances of above normal temperatures, near
normal temperatures, or below normal temperatures. CPC is also
forecasting a 33% chance of above normal precipitation, 34% chance
of near normal precipitation, and 33% chance of below normal
precipitation amounts for most of southeast Texas (essentially
equal chances for each outcome).

The three-month outlook (for September through November) from the
CPC shows southeast Texas with a 46% chance of above normal
temperatures, 33% chance for near normal temperatures, and 21%
chance for below normal temperatures. With regards to rainfall,
the three-month outlook from CPC shows southeast Texas with a 33%
chance of above normal precipitation, 34% chance of near normal
precipitation, and 33% chance of below normal precipitation
amounts.

.HYDROLOGIC SUMMARY...

.Streamflow Status...
According to the USGS real-time streamflows, many river gauge
locations across the area are running near normal to slightly
above normal with the exception of a few select locations that are
below normal along the Colorado River and headwaters of the Lavaca
Navidad River basin.


.Reservoir Status as of 9/9...
