...Exceptional drought conditions continue across most of Zapata
County and extreme western portions of Jim Hogg and Starr counties...
...Extreme drought conditions expand across northern Jim Hogg and
southeastern Cameron counties...

.SYNOPSIS...

Some much needed rainfall has occurred over the past 24 hours across
the northwestern counties. Early radar estimates show generally 1 to
2 inches of rain have fallen across northern Zapata and western Jim
Hogg counties. Most of the Rio Grande Valley has missed any
substantial rainfall to this point of the weekend. Over the past 90
days...the majority of rainfall has fallen across the northern
ranchlands of Deep South Texas. Northern Zapata, most of Jim Hogg,
and northeastern Starr into northwestern Hidalgo counties have all
received anywhere between 25 to 100 percent of their normal
rainfall. The rest of Deep South Texas, including the Rio Grande
Valley have received between 10 to 50 percent of their normal
rainfall.

According to the latest United States Drought Monitor...Exceptional
(D4) drought conditions continue across most of Zapata County and
extreme western Jim Hogg and Starr counties. Extreme (D3) drought
conditions have expanded across northern Jim Hogg and southeastern
Cameron counties, while continuing across the remainder of northern
Zapata, most of Jim Hogg, most of Starr, and portions of Hidalgo
counties. Severe (D2) drought conditions continue across the
remainder of Deep South Texas aside from central Kenedy County to
east-central Brooks County, where moderate (D1) drought conditions
were observed. Drought conditions are affecting agricultural
interests and grasslands as well as hydrologic and ecologic
interests across most of Deep South Texas.

SUMMARY OF IMPACTS...

FIRE DANGER IMPACTS.

According to the Significant Wildland Fire Potential Outlook by the
National Interagency Fire Center on April 1st, the potential for
significant wildland fires across Deep South Texas is generally
normal for April 2020 through July 2020. The latest observed Fire
Danger Map from the Texas Inter-Agency Coordination Center (TICC) on
April 4th indicated moderate fire danger across extreme southern
Hidalgo County and low fire danger across the remainder of Deep
South Texas.

The latest Keetch-Byram Drought Indices (KBDI) were generally 600 to
700 over Starr and Hidalgo counties, with pockets of KDBI values
between 600 to 800 across southern Zapata and western Starr
counties, as well as values of 600 to 700 across southeastern
Cameron County. KDBI values of 500 to 600 were generally found over
the remainder of Deep South Texas.

Residents of Deep South Texas, especially across Zapata, Jim Hogg,
Starr, Brooks, Willacy, and Hidalgo counties are urged to take extra
precautions when conducting any outside burning, and should contact
county officials for any scheduled burning. 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...weather conditions were mild
with very short to adequate soil moisture levels. Pasture and
rangeland conditions were in poor condition in most areas but
starting to improve in areas with recent rainfall. Irrigated sorghum
fields in Hidalgo County were stressed due to 95 degree days. Oats
and wheat continue to mature early due to dry conditions. Zapata
County reported some bare pastures. Producers in Zapata continue to
sell off cattle or feed hay and cubes. Little to no planting was
occurring in Starr and Kenedy counties due to drought, and pastures
looked extremely stressed.

WATER RESTRICTIONS.

According to the Texas Commission of Environmental Quality
(TCEQ)...there are 32 cities or water supply entities that are under
voluntary or mandatory water restrictions. There are 8 Public Water
Supply entities in Cameron county, 13 in Hidalgo county, 6 in Starr
county, 3 in Zapata county and 2 in Willacy county. All water users
are urged to conserve water.

PRECIPITATION/TEMPERATURE OUTLOOK...

Meteorological outlook...A cold front has moved through Deep South
Texas and stalled across the offshore Gulf of Mexico waters through
the weekend. The frontal boundary is expected to retreat north as a
warm front on Monday. A surface trough of low pressure is expected
to develop across northern Mexico and help continue a chance of
rainfall across western counties through the week. Another cold
front is expected to arrive on Friday, with high pressure building
into next weekend. Nearly every day into next Saturday has a chance
of rain, with the best chances occurring this weekend and across
western counties this week. Temperatures warm this week, with highs
into the 90s expected Tuesday through Thursday and more seasonal 80
degree highs next weekend.

Rainfall totals will generally range from one quarter of an inch to
three quarters of an inch through April 12th. Overall, above normal
rainfall is expected through April 14th.

Temperatures will generally be near normal this weekend, above
normal this week, and near normal again through Sunday, April 12th.
Overall, near normal temperatures are expected through April 14th.

The long range climate outlook for Deep South Texas through June
2020...derived from guidance from the National Weather Service and
the Climate Prediction Center...indicates that above normal
temperatures and below normal rainfall are expected for Deep South
Texas through the Spring of 2020. The latest monthly drought outlook
indicates that drought will persist across Deep South Texas through
April and the seasonal drought outlook indicates that the drought
will persist across the area through June 2020.

HYDROLOGIC SUMMARY AND OUTLOOK...

According to the Texas Water Development Board (TDWB)...the current
Texas water share at Falcon Reservoir has decreased during the past
four weeks to 26.2 percent. This is a decrease from the previous
level of 32.2 percent three months ago. The Texas water share at
Falcon at this time last year was at 49.8 percent. The current Texas
water share at Amistad Reservoir has decreased during the past four
weeks to 68.6 percent. This is also a decrease from a previous level
of 75.0 percent three months ago. The Texas water share at Amistad
at this time last year was at 76.9 percent. The reservoirs at Falcon
and Amistad provide much of the water for the Rio Grande Valley.
Residents, including growers and ranchers of the lower Rio Grande
Valley are urged to take all necessary steps to conserve water.
