Drought Information Statement
National Weather Service Corpus Christi TX
1125 PM CDT Wed Sep 18 2019

...RECENT RAINS IMPROVE DROUGHT CONDITIONS ONLY SLIGHTLY...

SYNOPSIS...

After a brief period of Extreme Drought (D3) conditions across
portions of South Texas, not only across the southern Brush
Country, but also into the Coastal Bend across Nueces and San
Patricio Counties as well as northwest La Salle County, some
improvements have been observed due to recent beneficial rainfall.
The latest Drought Monitor as of September 10 has most of South
Texas under Moderate Drought (D1). Southern portions of the Brush
Country along with portions of Nueces and San Patricio Counties
and the northwestern 2/3rds of La Salle County are under Severe
Drought (D2) conditions. Abnormally Dry (D0) conditions are
observed across extreme eastern Calhoun County, most of Kleberg
County, eastern McMullen County, western Live Oak County, and
northwestern Webb County. September is climatologically the
wettest month of the year for South Texas, especially as we enter
the peak of Hurricane Season, so hopefully we see additional
improvement.

SUMMARY OF IMPACTS...

WATER RESTRICTIONS.

Best practices for Water Conservation:
- Only water landscapes to maintain adequate soil moisture.
- Only water lawn if rainfall has not fallen in 1-2 weeks.
- Use a sprinkler which makes larger water droplets.
- Turn sprinklers toward the lawn and not the pavement.
- Avoid watering on windy days.
- Turn soaker hoses holes downward, facing the grass.

CORPUS CHRISTI - No restrictions.
http://www.cctexas.com/conservation
http://portlandtx.com
http://inglesidetx.gov

The city of Corpus Christi draws its water from both Lake Corpus
Christi and Choke Canyon Reservoir. When the combined water
capacity of both of these reservoirs falls below 40%, Stage 1 in
water restrictions begin. The current combination capacity as of
September 17, 2019 is 59.6%.

VICTORIA - No restrictions.
www.victoriatx.org/resident/news-releases-699

The city of Victoria draws its water from the Guadalupe River as
well as Canyon Lake upstream along the Guadalupe River. When the
Victoria USGS (United States Geological Survey) river gauge on the
Guadalupe falls below normal, Stage 1 in water restrictions
begin.

LAREDO - No restrictions.
http://www.cityoflaredo.com/utilities/water-conservation.html

The city of Laredo draws its water from the Amistad Reservoir
located along the Rio Grande. When the water capacity of the
reservoir reaches and falls below 51%, Stage 1 in water
restrictions begin. The current capacity as of September 17, 2019
is 75.9%.

For other public water systems (PWS) which may have water use
limits for the locals:
www.tceq.texas.gov/drinkingwater/trot/droughtw.html

Locations that do not currently have mandatory restrictions
continue to strongly promote year-round water conservation.


SOIL MOISTURE IMPACTS.

As of September 13, the Climate Prediction Center (CPC) analyzes
the percent of available soil moisture as near normal across South
Texas. The available soil moisture ranges from 10 to 30 percent
of normal across the region.


AGRICULTURAL IMPACTS.

Texas Crop and Weather Report from Texas A&M AgriLife as of:
September 11, 2019

Coastal Bend Region:
-Spotty rain observed, but most areas continue to experience
 short soil moisture.
-Livestock producers feeding hay and protein due to poor pasture
 conditions.
-Livestock water was starting to get low. Producers concerned
 above volume and muddy conditions that could cause livestock to
 get stuck.

South Region:
-Hot and dry conditions with short to very short moisture levels.
 Pastures remained dry. However, recent rain should improve
 pasture and rangeland in areas that received significant amounts.
-Live Oak County reported up to 3.5 inches of rainfall. Jim Wells
 up to 3 inches. Duval between 1-3 inches with adequate soil
 moisture.
-Drought conditions caused some struggles on ranches as water
 tanks began drying out.
-Cotton harvest continues. A little rain further delayed some
 cotton harvest and will likely affect lint quality of cotton in
 the field.
-Some supplemental feeding was reported.


FIRE DANGER HAZARDS.

Fire Danger Map - September 13, 2019
According to the latest Observed Fire Danger Map from the Texas
Interagency Coordination Center (TICC), Moderate to Low fire
danger covers South Texas. This is an improvement due to the
recent rainfall.

Keetch-Bryam Drought Index (KBDI)
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 KDBI for counties across the region
as of Sept 17, 2019.

CLIMATE SUMMARY...


Climate Prediction Center - September 12, 2019
ENSO Alert System Status: Not Active
(El-Nino/Southern Oscillation)

ENSO-Neutral conditions were reflected by near-average sea
surface temperatures (SSTs) across most of the central and eastern
equatorial Pacific Ocean. Computer models continue to favor ENSO-
Neutral conditions through Northern Hemisphere Spring 2020. In
summary, ENSO-Neutral is favored during Northern Hemisphere Fall
2019 (~75%) and through Northern Hemisphere Spring 2020 (55-60%).

Typically, El Nino promotes cooler and wetter weather and
suppresses tropical systems in the Atlantic Ocean, while La Nina
promotes warmer and drier weather and promotes more tropical
activity in the Atlantic. ENSO-Neutral is the period between El
Nino and La Nina conditions where weather and tropical systems
could go either way. There could be equal chances of either below,
above, or near normal temperatures and precipitation.

South Texas Summary - September 17, 2019
September, so far, has brought much needed rain to South Texas,
and with it being the climatological wettest month, it is very
welcomed. Rainfall amounts have averaged 1.0 to 3.0 inches across
the climate sites, although, some locations across the Brush
Country have averaged less than 1.0 inch. Temperatures have been
running about 1 to 4 degrees above normal.

The following table through the month of August shows:
- Monthly rainfall totals (deficits/surplus) in inches.
- Yearly rainfall totals (deficits/surplus) for 2019 in inches.
- Average monthly temps (departure from normal) in degrees F

                   AUGUST            2019         AUG AVG TEMPS
CORPUS CHRISTI   0.20 (-2.72)    11.71  (-7.63)    87.4 (+2.7)
VICTORIA         1.04 (-1.81)    15.68 (-11.19)    87.7 (+3.4)
LAREDO              T (-1.88)     3.77  (-9.22)    92.5 (+4.1)


PRECIPITATION/TEMPERATURE OUTLOOK...


Local forecast through the next 7 days (SEP 18 - SEP 24):
Moisture from the briefly-lived Tropical Storm Imelda will
continue to impact SE Texas into portions of South Texas. Daily
chances for showers and thunderstorms are expected, mainly toward
the Victoria Crossroads and adjacent gulf waters. Temperatures are
expected to range near seasonal normal for the coastal region,
with slightly above seasonal normal across the Brush Country.

CPC outlook for days 8-14 (SEP 25 - OCT 1):
Above normal temperatures are expected across all of South Texas.
Slightly above normal rainfall is expected for all of South
Texas.

CPC outlook for 1 month (SEP):
Above normal temperatures with equal chances of above, below, and
near normal precipitation.

CPC outlook for 3 months (SEP - NOV):
Above normal temperatures with equal chances of above, below, and
near normal precipitation.


HYDROLOGIC SUMMARY AND OUTLOOK...


USGS Streamflow Map - September 16, 2019.
Near to above normal streamflow for most rivers. Below normal
flow along Mission River at Refugio. Much below normal flow along
Garcitas Creek at Inez, Coleto Creek near Schroeder, and Atascosa
River at Whitsett.

The following table shows the current reservoir levels as of
September 1, 2019:

Reservoir           Normal Pool   Current Pool    % of Capacity
Choke Canyon          220.5 FT       204.5 FT         49.4%
Lake Corpus Christi    94.0 FT        92.5 FT         88.7%
Lake Texana            44.0 FT        40.9 FT         82.9%
Coleto Creek           98.0 FT        96.0 FT          N/A
Canyon Lake*          909.0 FT       908.4 FT          N/A
Lake Amistad**       1117.0 FT      1085.1 FT          N/A

* Supplies the city of Victoria
** Along Rio Grande, upstream of Laredo

Combined             Current Pool %   Last Year %   Difference
Choke Canyon/Lake CC     60.3%           35.3%        +25.0

With the exception of Choke Canyon, most reservoirs are mostly
full. However, with the continued lack of sufficient rainfall
across the river basins, reservoir levels will continue to fall
through the late summer months due to continued water usage.

NEXT ISSUANCE DATE...

The next Drought Information Statement will be issued on or near
October 15, 2019. If drought conditions worsen, an update may be
provided at an earlier date.
