...Drought conditions have ended across most of Deep South Texas...
...Moderate drought will likely end across southeastern Cameron
County...

.SYNOPSIS...

The active pattern of unsettled weather continued with moderate to
heavy rainfall across most of Deep South Texas over the past two
weeks, ending drought conditions for all but portions of
southeastern Cameron County. Over the past 90 days...the majority of
rainfall has fallen across northern Zapata and Jim Hogg counties,
down into the upper valley in Starr County and east across the
northern ranchlands into the Kenedy County coast. Most of Zapata and
Jim Hogg counties have received anywhere between 200 to 300 percent
of their normal rainfall. Starr, Kenedy, Brooks, and portions of
both western Hidalgo, and northeastern Willacy counties received
anywhere between 125 to 200 percent of their normal rainfall. The
rest of Deep South Texas, including southeastern Hidalgo,
southwestern Willacy, and most of Cameron County have received
anywhere between 75 to 125 percent of their normal rainfall, with
the southern most point of Cameron ranging 50 to 90 percent of
normal rainfall.

According to the latest United States Drought Monitor...Severe (D2)
drought conditions have improved and are no longer observed across
Deep South Texas. Moderate (D1) drought conditions have improved and
are only still observed across extreme southeastern Cameron County.
Abnormally dry (D0) conditions were still being observed across
portions of east-central Hidalgo County, southwestern Willacy
County, and from northwestern to southeastern Cameron County.

SUMMARY OF IMPACTS...

FIRE DANGER IMPACTS.

According to the Significant Wildland Fire Potential Outlook by the
National Interagency Fire Center on June 1st, the potential for
significant wildland fires across Deep South Texas is generally
normal for June 2020 through September 2020, with below normal
potential for significant wildland fires across coastal counties for
June 2020 and July 2020. The latest observed Fire Danger Map from
the Texas Inter-Agency Coordination Center (TICC) on June 8th
indicated a moderate fire danger across Zapata, Starr, Jim Hogg,
western Brooks, eastern Willacy, and eastern Cameron counties, with
a low fire danger across Kenedy, eastern Brooks, Hidalgo, western
Willacy, and western Cameron counties.

The latest Keetch-Byram Drought Indices (KBDI) were generally 400 to
600 over southeastern and northwestern Cameron County, eastern
Hidalgo County, and southwestern Willacy County. KBDI values between
300 to 400 were found across most of Starr County, the remainder of
Cameron County, southwestern Hidalgo County, and southern Brooks
County. KBDI values of 200 to 300 were found across the remainder of
Starr County, southern Zapata County, southeastern Jim Hogg County,
most of Brooks County, the remainder of Willacy County, and
northeastern Kenedy County. KBDI values of 0 to 200 were found
across the remainder of Zapata, Jim Hogg, Brooks, and Kenedy
counties.

Residents of Deep South Texas, especially across Zapata, Jim Hogg,
Starr, Brooks, and Willacy counties are still 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. Rainfall of 3 to
4.5 inches was reported in Zapata County. Growing conditions were
good and improving in many areas. Many reported stock tanks were
filled, with moisture expected to help forage producers. Pasture and
rangeland conditions continued to improve with recent rainfall. Very
little supplemental feeding of livestock was reported.

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.

CLIMATE SUMMARY...

Overall, the month of June 2020 has started above normal for
temperatures and above normal for rainfall across Deep South Texas.

Rainfall through June to date at Brownsville was 1.20 inches, or
0.58 of an inch above normal. Total rainfall for 2020 to date is
4.67 inches, or 3.71 inches below normal.

Rainfall through June to date at Harlingen was 1.53 inches, or 0.98
of an inch above normal. Total rainfall for 2020 to date is 5.57
inches, or 2.90 inches below normal.

Rainfall through June to date at McAllen was 1.58 inches, or 0.92 of
an inch above normal. Total rainfall for 2020 to date is 9.50
inches, or 2.06 inches above normal.

PRECIPITATION/TEMPERATURE OUTLOOK...

Meteorological outlook...Potentially the hottest day of the year to
date is expected today, with a weak cold front arriving tomorrow and
stalling into Thursday, bringing near normal temperatures back to
Deep South Texas into next week. The best chance of rainfall will
reside with the front and any seabreeze convection that can develop
Wednesday and Thursday, with dry conditions returning and
persisting into next week.

Rainfall totals are expected to range between one tenth of an inch
to around one half of an inch through Monday, June 15th, with the
bulk of any rainfall remaining generally southwest along the Rio
Grande. Overall, slightly below normal rainfall is expected through
Thursday, June 18th.

Temperatures are expected to remain generally near normal this week
into next week through Monday, June 15th. Overall, near normal to
just above normal temperatures are expected through Thursday, June
18th.

The long range climate outlook for Deep South Texas through August
2020...derived from guidance from the National Weather Service and
the Climate Prediction Center...indicates that above normal
temperatures and equal chances of above or below normal rainfall are
expected for Deep South Texas into late summer. The latest monthly
drought outlook indicates that drought removal is likely across the
remainder of Deep South Texas through June and the seasonal drought
outlook indicates that drought removal is likely across most areas
experiencing drought, and will remain, but improve across most of
the lower Rio Grande Valley, including Cameron County, through
August 2020.

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 32.2 percent. This is slightly above the previous
level of 31.4 percent three months ago. The Texas water share at
Falcon at this time last year was at 38.1 percent. The current Texas
water share at Amistad Reservoir has decreased during the past four
weeks to 58.6 percent. This is a decrease from a previous level of
69.1 percent three months ago. The Texas water share at Amistad at
this time last year was at 82.3 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.
