...Severe drought conditions have developed across portions of deep
...Moderate drought conditions continue across other portions of
deep South Texas...
Rainfall was below normal across most of deep South Texas during the
month of January except for an area across southeast portions of
Hidalgo county into extreme northwest portions of Cameron county
into portions of Willacy county. During the last 90 days...most of
deep South Texas has received anywhere from 25 to 75 percent of
their normal rainfall except for the areas mentioned above.
According to the latest United States Drought Monitor...given the
persistent short term dryness, drought conditions continue to worsen
over the region. Abnormally dry conditions (D0) exist over southern
portions of Zapata, Jim Hogg, Hidalgo and Willacy counties as well
as over most of Brooks and Cameron counties. Moderate (D1) drought
exists across northern portions of Hidalgo and Willacy counties as
well as over most of Starr and Kenedy counties and extreme southwest
portions of Cameron county. Severe (D2)drought exists over extreme
northeast portions of Starr county...extreme northern portions of
Hidalgo county and extreme northeast portions of Kenedy county.
Drought conditions across deep South Texas are affecting mainly
agricultural interests and grasslands.
SUMMARY OF IMPACTS...
FIRE DANGER IMPACTS.
Last year`s rainfall has provided a fine fuel crop for the area and
with cured grass fuel loadings being high, the risk for large/rapid
fire spread exists should ignition occur in a higher wind/low
relative humidity period. According to the National Interagency Fire
Center, the potential for significant wildland fires is above normal
for the area. The latest Fire Danger Map from the Texas Inter-Agency
Coordination Center (TICC) on February 10th indicates a moderate
fire danger over the area. The forecast fire danger for February
11th varies from moderate across western portions of deep South
Texas to high across eastern portions with very high across portions
of Hidalgo county. The latest Keetch-Byram Drought Indices (KBDI)
were 400 to 500 over most of Zapata...Jim Hogg and Willacy counties.
KBDI`s of 500 to 600 were over most of Brooks...Kenedy and Cameron
counties. KBDI`s of 600 to 700 were over portions of Starr and
Hidalgo counties. County burn bans are currently in effect for
Zapata, Jim Hogg, Brooks and Starr 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.
According to the United States Department of Agriculture and Texas
Agrilife Extension Service Agents...soil moisture conditions over
the region were adequate to short. Field work started or continued
for spring cotton, corn and sorghum planting. Pasture and range
conditions were fair to poor and were declining in most areas.
Supplemental feeding for livestock continued.
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.
Overall, January 2017 brought above normal temperatures and below
normal rainfall across most of deep South Texas, except across
southeast portions of Hidalgo county, extreme northwest portions of
Cameron county and southern/eastern portions of Willacy county
where near normal rainfall fell.
Current rainfall to date for the month of February at Brownsville is
1.21 inches or 0.71 inches above normal. Year to date rainfall is
1.39 inches or 0.38 inches below normal.
Current rainfall to date for the month of February at Harlingen is
0.29 inches or 0.35 inches below normal. Year to date rainfall is
1.19 inches or 0.51 inches below normal.
Current rainfall to date for the month of February at McAllen is
0.30 inches or 0.17 inches below normal. Year to date rainfall is
1.28 inches or 0.24 inches below normal.
Meteorological outlook...February 12th through February 20th...the
combination of a cold front moving into south Texas and low pressure
developing across northeast Mexico will provide significant rainfall
across the area the 12th through the 14th before surface high
pressure builds into deep south Texas on the 15th. Temperatures will
be above normal through the 14th before becoming below normal the
15th and 16th. Overall average temperatures will be above normal
from February 16th through February 20th for mid February.
Rainfall totals will generally range from half an inch to an inch
across deep South Texas through February 17th. Overall average
rainfall will be near normal to above normal from February 16th
through February 20th. Any rainfall that occurs through February
will provide some drought relief for the area.
The long range climate outlook for deep South Texas through April
2017...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/near normal/above
normal rainfall will be expected for deep South Texas into the
Spring of 2017. At this time...the potential for drought conditions
ending through April 2017 is low.
Any rainfall that affects deep south Texas through April 2017 will
provide some 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 increased during the past
four weeks to 38.2 percent. This is an improvement from a previous
level of 35.6 percent three months ago. The Texas water share at
Falcon at this time last year was at 52.6 percent. The current Texas
water share at Amistad Reservoir has decreased during the past four
weeks to 82.8 percent. This is a lowering from a previous level of
83.8 percent three months ago. The Texas water share at Amistad at
this time last year was at 67.0 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.
Any rainfall that falls into the Rio Grande watershed early next
week upstream of Falcon and Amistad will help recharge reservoir
