.SYNOPSIS...

Rainfall has been below normal across most of deep south Texas
for the month of May except across portions of Jim Hogg county
as well as southern portions of Zapata and Starr counties where
rainfall has been normal to above normal. During the last 90
days...deep South Texas has received anywhere from 25 to 100 percent
of their normal rainfall except across portions of Starr
county...northern portions of Jim Hogg county and southern portions
of Zapata county where 100 to 200 percent of normal rainfall fell.

According to the latest United States Drought Monitor...Severe (D2)
drought conditions have developed across northern portions of
Cameron county...most of Willacy county...southeast portions of
Kenedy county and northeast portions of Brooks county. Moderate (D1)
drought conditions were across the rest of Cameron county...the rest
of Kenedy county...eastern portions of Brooks county and extreme
northern and eastern portions of Hidalgo county as well as extreme
northern portions of Zapata county. Abnormally dry conditions (D0)
were across the remainder of deep South Texas except across most of
Starr county...extreme southern portions of Zapata county and
extreme northern portions of Jim Hogg county. Drought conditions
across deep South Texas are affecting agricultural interests and
grasslands.

SUMMARY OF IMPACTS...

FIRE DANGER IMPACTS.

According to the National Interagency Fire Center, the potential for
significant wildland fires is normal.  The latest Fire Danger Map
from the Texas Inter-Agency Coordination Center (TICC) on June 7th
indicated a very high fire danger across southern portions of Starr
county...a high fire danger across southern and western portions of
deep South Texas...a moderate fire danger across northern and
eastern portions of deep South Texas and a low fire danger across
eastern portions of Cameron county. The latest Keetch-Byram Drought
Indices (KBDI) were 500 to 600 over Zapata, Starr, and Jim Hogg
counties and 600 to 700 across the rest of deep South Texas. County
burn bans are currently in effect for Zapata, Jim Hogg, Brooks,
Starr and Willacy counties. Residents 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.

AGRICULTURAL IMPACTS.

According to the United States Department of Agriculture and Texas
Agrilife Extension Service Agents...short to very short moisture
levels continue across the area. Pasture and rangeland conditions
continue to decline due to high temperatures and no rainfall.
Supplemental feeding of livestock and wildlife continue to increase.
Body conditions scores on cattle remain fair. Stock tank levels were
falling and some producers started to haul water while others began
to cull herds. Row-crop conditions declined significantly in some
parts and yield potential was expected to be reduced.

WATER RESTRICTIONS.

According to the Texas Commission of Environmental Quality
(TCEQ)...there are currently 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.

CLIMATE SUMMARY...

Overall, May 2018 brought above normal temperatures and below normal
rainfall across most of deep South Texas except across portions of
Jim Hogg county as well as southern portions of Zapata and Starr
counties where rainfall has been normal to above normal.

Current rainfall to date for the month of June at Brownsville is
0.00 inches or 0.55 inches below normal. Year to date rainfall is
5.30 inches or 3.01 inches below normal.

Current rainfall to date for the month of June at Harlingen is a

Current rainfall to date for the month of June at McAllen is 0.00
inches or 0.57 inches below normal. Year to date rainfall is 3.82
inches or 3.53 inches below normal.

PRECIPITATION/TEMPERATURE OUTLOOK...

Meteorological outlook...June 8th through June 13th...An upper level
ridge of high pressure across northern Mexico and west Texas will
weaken slightly June 8th through June 10th allowing isolated
seabreeze showers and thunderstorms to develop across the coastal
sections of deep South Texas and move inland. An upper level ridge
of high pressure will amplify across the southwest United States
June 11th and move slightly eastward June 12th. Some weakness in the
upper level ridge will develop across South Texas June 12th and
13th. This will allow some isolated seabreeze showers and
thunderstorms to develop across the coastal sections of deep South
Texas and move inland on the 12th and 13th.

Temperatures will be above normal from June 8th through June 11th
and near normal to above normal June 12th and 13th. Overall average
temperatures will be above normal from June 13th through June 17th.

Rainfall totals will generally be less than a hundredth of an inch
across deep South Texas through June 14th. Overall average rainfall
will be near normal from June 13th through June 17th.

The long range climate outlook for deep South Texas through August
2018...derived from guidance from the National Weather Service and
the Climate Prediction Center...indicates that generally above
normal temperatures and equal chances of below normal...normal or
above normal rainfall will be expected for deep South Texas through
the Summer of 2018. The latest seasonal drought outlook indicates
that drought is likely to persist across some portions of deep South
Texas and develop across the rest of deep South Texas through the
Summer of 2018.

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 30.7 percent. This is a decrease from a previous level
of 54.1 percent three months ago. The Texas water share at Falcon at
this time last year was at 33.4 percent. The current Texas water
share at Amistad Reservoir has decreased slightly during the past
four weeks to 72.6 percent. This is a slight decrease from a
previous level of 75.4 percent three months ago. The Texas water
share at Amistad at this time last year was at 79.6 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.

NEXT ISSUANCE DATE...
