...Moderate drought conditions have developed across southeast
portions of Hidalgo County...
...Moderate drought conditions have expanded across most of Cameron
County...

.SYNOPSIS...

Rainfall was above normal across portions of the upper Rio Grande
valley and northwest ranchlands as well as across portions of the
King Ranch during the month of May. Rainfall was below normal across
Cameron...Hidalgo and Willacy counties as well as across portions of
Jim Hogg and Brooks counties. During the last 90 days...deep South
Texas has received anywhere from 75 to 150 percent of their normal
rainfall except across portions of Cameron and Hidalgo counties
where 25 to 75 percent of normal rainfall fell.

According to the latest United States Drought Monitor...moderate
(D1) drought conditions have developed across southeast portions of
Hidalgo county. Moderate (D1) drought conditions have expanded
across most of Cameron county. Abnormally dry conditions (D0) have
expanded across the southern half of Hidalgo county and have
developed into extreme southern portions of Willacy county. Drought
conditions across deep South Texas are affecting mainly 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 for the area. The latest Fire
Danger Map from the Texas Inter-Agency Coordination Center (TICC) on
June 22nd indicates a moderate fire danger over most of the area
except for high across the southeast portions of Hidalgo and Kenedy
counties as well most of Willacy and Cameron counties and very high
across eastern portions of Cameron county. The latest Beech-Byram
Drought Indices (KBDI) were 300 to 400 over Kenedy, Brooks and
Zapata counties. KBDI`s of 400 to 500 were over Willacy, Jim Hogg
and Starr counties. KBDI`s of 500 to 600 were over Cameron and
Hidalgo counties. 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...rangeland and pastures were
showing signs of stress but crop production benefited from the hot
and dry weather. Fire danger increased because of very dry forage.
Most pastures remained very green from rains that occurred during
the previous reporting period. Body condition scores on cattle
remained fair. The live cattle market dropped a small percentage in
Brooks county. Corn was maturing and sorghum was turning color.
Cotton was moving from the squaring stage to the boll-setting stage.

WATER RESTRICTIONS.

According to the Texas Commission of Environmental Quality
(TCEQ)...there are currently 31 cities or water supply entities that
are under voluntary or mandatory water restrictions. There are 7
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 2017 brought near normal to above normal temperatures
and near normal to above normal rainfall across most of deep South
Texas, except across portions of Cameron...Hidalgo and Willacy
counties where below normal rainfall fell.

Current rainfall to date for the month of June at Brownsville is a
trace or 1.81 inches below normal. Year to date rainfall is 5.86
inches or 3.71 inches below normal.

Current rainfall to date for the month of June at Harlingen is 0.07
inches or 1.62 inches below normal. Year to date rainfall is 6.66
inches or 2.95 inches below normal.

Current rainfall to date for the month of June at McAllen is 0.07
inches or 1.80 inches below normal. Year to date rainfall is 5.94
inches or 2.71 inches below normal.

PRECIPITATION/TEMPERATURE OUTLOOK...

Meteorological outlook...June 23rd through July 2nd...An upper level
trough of low pressure across the western Gulf of Mexico and a weak
cold front will move into South Texas on the 24th possibly providing
significant rainfall across portions of deep South Texas the 24th
through the 27th. Temperatures will be above normal on the 23rd.
Near normal temperatures can be expected the 24th through the 28th.
Overall average temperatures will be near normal from June 28th
through July 2nd for late June into early July.

Rainfall totals will generally range from a quarter of an inch to 1
inch across portions of deep South Texas through June 29th. Overall
average rainfall will be near normal from June 28th through July
2nd. Any rainfall that occurs in the southern portions of Hidalgo
county as well as across most of Cameron county through the rest of
June will provide some drought relief for the area.

The long range climate outlook for deep South Texas through
September 2017...derived from guidance from the National Weather
Service and the Climate Prediction Center...indicates that generally
above normal temperatures and above normal rainfall will be expected
for deep South Texas through the rest of the Summer of 2017. At this
time...the potential for drought conditions ending through September
2017 is moderate to high.

Any rainfall that affects deep south Texas through September 2017
will provide drought relief from the current drought conditions.

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 30.5 percent. This is a lowering from a previous level
of 41.2 percent three months ago. The Texas water share at Falcon at
this time last year was at 45.7 percent. The current Texas water
share at Amistad Reservoir has decreased during the past four weeks
to 78.0 percent. This is a lowering from a previous level of 79.7
percent three months ago. The Texas water share at Amistad at this
time last year was at 74.2 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.
