Drought Information Statement
National Weather Service Brownsville TX
250 AM CDT Fri Sep 9 2022

...Extreme and severe drought conditions have ended across Deep
South Texas...
...Moderate drought conditions continue across western Zapata and
Starr counties...

.SYNOPSIS...

Abundant tropical moisture and multiple rounds of much needed
rainfall have continued to improve drought conditions across most
of Deep South Texas. After historic to near historically low
reservoir levels in mid-August, persistent rainfall across the
watershed has steadily improved storage over the past month.

Over the past 90 days...the majority of rainfall has fallen
across the northern ranchlands of eastern Jim Hogg, Brooks,
Kenedy, and northeastern Starr counties. Southeastern Cameron
County has received between 25 and 75 percent of normal rainfall.
Portions of central and western Cameron, eastern to central
Hidalgo, western Jim Hogg, and central Zapata counties have
received between 75 and 110 percent of normal rainfall. The
remainder of Zapata, most of Jim Hogg, most of Starr, Brooks,
Kenedy, western Hidalgo, Willacy, and northern Cameron counties
have received between 110 and 200 percent of normal rainfall, with
portions of northeastern Starr and southeastern Jim Hogg receiving
between 200 and 300 percent of normal rainfall.

According to the latest United States Drought Monitor...Extreme
(D3) drought and severe (D2) drought conditions have ended across
Deep South Texas. Moderate (D1) drought conditions have improved
across most of Zapata and western Starr counties, while continuing
across western portions of Zapata and extreme southwestern Starr
counties. Abnormally dry conditions were found across most of the
remainder of Zapata and western Starr counties.

SUMMARY OF IMPACTS...

FIRE DANGER IMPACTS.

According to the Significant Wildland Fire Potential Outlook by
the National Interagency Fire Center on September 1st, the
potential for significant wildland fires across Deep South Texas
is normal for September through November 2022, and above normal
for December 2022. The latest observed Fire Danger Map from the
Texas Interagency Coordination Center (TICC) for September 8th,
indicated low fire danger across all of Deep South Texas.

The latest Keetch-Byram Drought Indices (KBDI) were generally
between 500 to 700 across southern to southeastern Cameron County.
KBDI values between 400 to 500 were across central Zapata,
southcentral Hidalgo, and central Cameron counties. KBDI values
between 200 to 400 were across portions of northern to central
Zapata, western Jim Hogg, northern Brooks, central to eastern
Hidalgo, western Willacy, and northern to central Cameron
counties. KBDI values of 0 to 200 were across the remainder of
Deep South Texas.

Residents of Deep South Texas are urged to take extra precautions
when conducting any outside burning, and should contact county
officials for any scheduled burning. The Texas Forest Service
reports Zapata, Brooks, Kenedy, and Starr counties as having
known burn bans currently in effect. Residents are also reminded
that fire danger can change quickly from one day to another as
winds and relative humidity values vary, especially after frontal
passages.

AGRICULTURAL IMPACTS.

According to the United States Department of Agriculture and
Texas Agrilife Extension Service Agents on September 7th...soil
moisture levels were short to adequate, with many areas reporting
multiple inches of rainfall, including isolated areas of 10
inches. Pastures and rangelands were greening up, and forage
conditions were improving rapidly in some areas. Irrigation
slowed for citrus and sugarcane. Livestock conditions were
improving, with ranchers still providing supplemental feed to both
livestock and wildlife. Producers were preparing fields for cool
season small grain planting.

WATER RESTRICTIONS.

According to the Texas Commission of Environmental Quality (TCEQ)
on September 2nd...there are 14 cities or water supply entities
reporting voluntary or mandatory water restrictions across Deep
South Texas. There are 3 public water supply entities in Cameron
County, 3 in Hidalgo County, 3 in Starr County, and 5 in Zapata
County.

All water users are urged to conserve water, with multiple cities
or water supply entities potentially adding additional water
restrictions not reported to TCEQ.

CLIMATE SUMMARY...

Abundant tropical moisture and persistent showers and
thunderstorms with moderate to heavy rainfall have maintained
above normal annual rainfall for portions of the northern
ranchlands and lower Rio Grande Valley, with locations across the
mid to upper valley and portions of the brush country remaining
below normal. McAllen received record rainfall totals this week,
boosting September rainfall totals well above normal. High
temperatures over the past couple of weeks have been kept near to
slightly below normal due to thick cloud cover and showers or
thunderstorms limiting peak heating.

Rainfall into September to this point at Brownsville was 1.0
inch, or 0.45 of an inch below normal. Rainfall to date in 2022
at Brownsville is 16.96 inches, or 1.26 inches above normal.

Rainfall into September to this point at Harlingen was 0.86 of an
inch, or 0.58 of an inch below normal. Rainfall to date in 2022
at Harlingen is 18.64 inches, or 4.21 inches above normal.

Rainfall into September to this point at McAllen was 2.97 inches,
or 1.72 inches above normal. Rainfall to date in 2022 at McAllen
is 11.94 inches, or 2.53 inches below normal.

PRECIPITATION/TEMPERATURE OUTLOOK...

Meteorological Outlook...High pressure builds across the region,
diminishing most rain chances across Deep South Texas, with
normal to slightly above normal high temperatures returning.
Seabreeze convection remains possible into this weekend.

Rainfall of a trace to 0.25 of an inch is expected into Friday,
September 16th across Deep South Texas. Overall, near normal
rainfall is expected through Sunday, September 18th.

Near normal high temperatures in the low to mid 90s are expected
through Tuesday, September 13th across Deep South Texas, with
below normal highs in the upper 80s to low 90s Wednesday through
Friday, September 16th. Near normal low temperatures in the low to
mid 70s across the ranchlands and mid to upper 70s across the
Rio Grande Valley and brush country are generally expected through
Friday, September 16th. Overall, above normal temperatures are
expected through Sunday, September 18th.

The long range climate outlook for Deep South Texas through
November 2022...derived from guidance from the National Weather
Service and the Climate Prediction Center...indicates that above
normal temperatures are generally expected for Deep South Texas
into late fall with equal chances of above normal or below normal
rainfall. The latest monthly drought outlook on August 31st
indicated that drought will remain but improve across western
Zapata County, with drought removal likely across eastern Zapata
and western Starr counties through September 2022. The latest
seasonal drought outlook on August 31st indicated that drought
will remain but improve across western Zapata County, with
drought removal likely across eastern Zapata and western Starr
counties through November 2022.

HYDROLOGIC SUMMARY AND OUTLOOK...

According to the Texas Water Development Board (TDWB)...the
current Texas water share at Falcon Reservoir has increased
during the past four weeks to 15.6 percent. This is a decrease
from a previous level of 20.3 percent three months ago. The Texas
water share at Falcon at this time last year was at 22.4 percent.
The current Texas water share at Amistad Reservoir has increased
during the past four weeks to 39.8 percent. This is an increase
from a previous level of 38.0 percent three months ago. The Texas
water share at Amistad at this time last year was at 52.8
percent.

The reservoirs at Falcon and Amistad provide much of the water
for the Rio Grande Valley and have continued to improve from near
combined record lows in mid August. Residents, including growers
and ranchers of the lower Rio Grande Valley are urged to take all
necessary steps to conserve water.
