...Drought conditions have ended over most of deep South Texas...
...Moderate drought conditions return across southern portions of
Rainfall was well above normal across most of deep South Texas
during the month of March except for an area across southern and
eastern portions of Cameron county where rainfall was slightly above
normal to near normal. During the last 90 days...deep South Texas
has received anywhere from 150 to 300 percent of their normal
rainfall except across portions of Cameron county where 50 to 150
percent of normal rainfall fell.
According to the latest United States Drought Monitor...recent rains
have brought an end to drought conditions across the area.
However...moderate (D1) conditions have returned across extreme
southern portions of Cameron county. Abnormally dry conditions (D0)
continue across most of the rest of Cameron county.
SUMMARY OF IMPACTS...
FIRE DANGER IMPACTS.
Some grasses in the lower Gulf Coast are transitioning from green to
cured with recent drying. 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 April 14th indicates a low fire danger
over most of the area except for moderate across the coastal
sections of Cameron and Willacy counties. The latest Beech-Byram
Drought Indices (KBDI) were 200 to 300 over Kenedy, Willacy, Jim
Hogg and Brooks counties. KBDI`s of 300 to 400 over Zapata, Starr
and Hidalgo counties. KBDI`s of 500 to 600 were over Cameron county.
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.
According to the United States Department of Agriculture and Texas
Agrilife Extension Service Agents...soil moisture conditions
declined in some areas due to lack of rain. Corn crops were
irrigated and sorghum crops were still being planted. Growing
conditions were very favorable for corn and sorghum following nice
rains in some areas. Pasture and row crop conditions were declining
in some areas due to above average temperatures and lack of
rainfall. Vegetable crops progressed well with tomato plants already
setting fruit. Livestock on native rangeland and pastures continued
to do well due to rapidly growing and improved native grasses
producing abundant forage for grazing and cattle body conditions
scores showed improvement.
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, March 2017 brought above normal temperatures and well above
normal rainfall across most of deep South Texas, except across
portions of Cameron county where near normal to above normal
Current rainfall to date for the month of April at Brownsville is
0.11 inches or 0.65 inches below normal. Year to date rainfall is
3.49 inches or 0.85 inches below normal.
Current rainfall to date for the month of April at Harlingen is 0.71
inches or 0.13 inches below normal. Year to date rainfall is 4.24

Meteorological outlook...April 16th through April 25th...an upper
level disturbance will move across portions of southwest and deep
South Texas the 16th through the 18th providing significant rainfall
across portions of deep South Texas the 16th through the 18th. Drier
air will filter into the area the 19th and 20th before moisture
returns ahead of a cold front the 21st and 22nd providing
significant rainfall across portions of deep South Texas on the
22nd. Temperatures will be near normal the 16th through the 18th
before returning to above normal on the 19th. Above normal
temperatures will continue through the 21st before returning to near
normal on the 22nd. Overall average temperatures will be near normal
from April 21st through April 25th for mid to late April.
Rainfall totals will generally range from a quarter of an inch to
one inch across portions of deep South Texas through April 22nd.
Overall average rainfall will be near normal from April 21st through
April 25th. Any rainfall that occurs in the southern portions of
Cameron county through April will provide drought relief for the
The long range climate outlook for deep South Texas through June
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 Spring of 2017 into early
Summer 2017. At this time...the potential for drought conditions
ending through June 2017 is moderate to high.
Any rainfall that affects deep south Texas through June 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 increased during the past
four weeks to 40.7 percent. This is an improvement from a previous
level of 34.5 percent three months ago. The Texas water share at
Falcon at this time last year was at 46.9 percent. The current Texas
water share at Amistad Reservoir has decreased during the past four
