...Drought conditions have ended over Cameron County...
...Moderate drought conditions continue across portions of Hidalgo
County...

.SYNOPSIS...

Rainfall was below normal across most of the Rio Grande valley and
northern ranchlands during the month of June. Rainfall was above
normal across most of Kenedy county...across southern portions of
Cameron county and northern portions of Brooks county. During the
last 90 days...deep South Texas has received anywhere from 75 to 150
percent of their normal rainfall except across southern portions of
Hidalgo county where 25 to 75 percent of normal rainfall fell.

According to the latest United States Drought Monitor...moderate
(D1) drought conditions continue across southeast portions of
Hidalgo county. Abnormally dry conditions (D0) continue across the
southern half of Hidalgo county and have developed across northern
portions of Jim Hogg 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
July 14th indicates a moderate fire danger over most of the area
except for high across northeast portions of Zapata county and
northern portions of Jim Hogg county. The latest Beech-Byram Drought
Indices (KBDI) were 300 to 400 over Kenedy county. KBDI`s of 400 to
500 were over Willacy, Cameron, Jim Hogg, Brooks and Zapata
counties. KBDI`s of 500 to 600 were over Starr 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...range and pastures continued to
decline due to excessive heat and no rainfall. In Jim Hogg county,
most pastures were turning yellow as the high heat and lack of
rainfall affected grass growth. Topsoil moisture and subsoil
moisture levels were adequate. In Kenedy county, corn harvesting was
almost complete and sorghum harvesting was in full swing. Range and
pastures showed signs of moisture depletion but remained in good
condition. Crops matured in most parts of Hidalgo county. Corn and
sorghum harvesting continued except for some rainfall that halted
the process for a couple of days. In Cameron county cotton
harvesting has begun and livestock were in good condition. Range and
pastures improved in Cameron and Starr counties with some rainfall.
Grain sorghum harvesting an hay-bailing continued in Starr county.

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, 14 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, June 2017 brought near normal to above normal temperatures
and below normal rainfall across most of deep South Texas, except
across portions of Kenedy county and southern portions of Cameron
county where above normal rainfall fell.

Current rainfall to date for the month of July at Brownsville is
2.26 inches or 1.11 inches above normal. Year to date rainfall is
11.61 inches or 0.13 inches above normal.

Current rainfall to date for the month of July at Harlingen is 0.80
inches or 0.33 inches below normal. Year to date rainfall is 8.65
inches or 2.90 inches below normal.

Current rainfall to date for the month of July at McAllen is 0.14
inches or 1.00 inches below normal. Year to date rainfall is 6.19
inches or 4.31 inches below normal.

PRECIPITATION/TEMPERATURE OUTLOOK...

Meteorological outlook...July 16th through July 21st...An upper
level trough of low pressure will move across the lower Texas coast
on the 16th possibly providing rainfall across portions of deep
South Texas the 16th and the 17th. Seabreeze showers and
thunderstorms will develop across the coastal sections of deep South
Texas from the 18th through the 20th. Temperatures will be near
normal to above normal from the 16th through the 20th. Overall
average temperatures will be above normal from July 21st through
July 25th for late June.

Rainfall totals will generally range from a tenth of an inch to half
of an inch across portions of deep South Texas through July 21st.
Overall average rainfall will be below normal from July 21st through
July 25th. Any rainfall that occurs in the southern portions of
Hidalgo county through the rest of July 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 26.0 percent. This is a lowering from a previous level
of 40.7 percent three months ago. The Texas water share at Falcon at
this time last year was at 39.5 percent. The current Texas water
share at Amistad Reservoir has decreased during the past four weeks
to 76.3 percent. This is a lowering from a previous level of 77.1
percent three months ago. The Texas water share at Amistad at this
time last year was at 75.2 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.
