Drought Information Statement
National Weather Service Brownsville TX
1205 PM CST Sat Mar 11 2017

...Drought conditions have improved dramatically across portions of
deep South Texas...

...Moderate drought conditions linger across portions of deep South
Texas...

.SYNOPSIS...

Rainfall was below normal across most of deep South Texas during the
month of February except for an area across western and northern
portions of Hidalgo and an area across western and northern portions
of Zapata county. During the last 90 days...deep South Texas has
received anywhere from 100 to 200 percent of their normal rainfall
except across portions of Cameron and Kenedy counties where 75 to
100 percent of normal rainfall fell.

According to the latest United States Drought Monitor...recent rains
have allowed for major improvements to the dryness across the area.
Abnormally dry conditions (D0) linger over most of Cameron, Hidalgo
and Starr counties as well as southern portions of Brooks county,
extreme western portions of Willacy county, eastern portions of
Kenedy county and extreme southeast portions of Jim Hogg county.
Moderate (D1) drought exists across eastern portions of Starr
county, western portions of Hidalgo county, southern portions of
Cameron 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.

A longer than normal fire season is expected due to current drought
and fuel conditions brought on by warm and dry weather which should
continue into the Spring. 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 March 11th 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 0 to 200 over Kenedy, Willacy and Brooks
counties. KBDI`s of 200 to 300 over Zapata, Jim Hogg, Starr and
Hidalgo counties. KBDI`s of 400 to 500 were over Cameron county.
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.

AGRICULTURAL IMPACTS.

According to the United States Department of Agriculture and Texas
Agrilife Extension Service Agents...soil moisture conditions over
the region remained short in most areas. Corn, grain sorghum and
cotton planting was very active in Hidalgo county. Sugarcane, citrus
and vegetable harvests were ongoing. Rangeland and pasture
conditions continued to improve as a result of rainfall and warmer
temperatures. Supplemental feeding of livestock continued and cattle
body conditions scores remained fair.

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 8
Public Water Supply entities in Cameron county, 13 in Hidalgo
county, 6 in Starr county, 4 in Zapata county and 2 in Willacy
county. All water users are urged to conserve water.

CLIMATE SUMMARY...

Overall, February 2017 brought above normal temperatures and below
normal rainfall across most of deep South Texas, except across most
of Zapata...Jim Hogg...Hidalgo and Willacy counties where near
normal to above normal rainfall fell.

Current rainfall to date for the month of March at Brownsville is
1.82 inches or 1.46 inches above normal. Year to date rainfall is
3.36 inches or 0.65 inches above normal.

Current rainfall to date for the month of March at Harlingen is 2.20
inches or 1.83 above normal. Year to date rainfall is 3.51 inches or
0.67 inches above normal.

Current rainfall to date for the month of March at McAllen is 2.51
inches or 2.14 inches above normal. Year to date rainfall is 4.14
inches or 1.61 inches above normal.

PRECIPITATION/TEMPERATURE OUTLOOK...

Meteorological outlook...March 12th through March 20th...a cold
front moving into south Texas tomorrow will provide significant
rainfall across the area on the 12th before surface high pressure
builds into deep south Texas on the 13th. Another surge of high
pressure will provide dry conditions across deep south Texas the
14th and 15th before moisture returns the 16th and 17th ahead of
another cold front moving into the area on the 18th...providing
significant rainfall for the 18th before drier air builds in on the
19th. Temperatures will be below normal on the 12th before returning
to near normal the 13th and 14th. Overall average temperatures will
be above normal from March 16th through March 20th for mid March.

Rainfall totals will generally range from a tenth of an inch to half
an inch across deep South Texas through March 18th. Overall average
rainfall will be below normal from March 16th through March 20th.
Any rainfall that occurs through March will provide additional
drought relief for the area.

The long range climate outlook for deep South Texas through May
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 through the
Spring of 2017. At this time...the potential for drought conditions
ending through May 2017 is low to moderate.

Any rainfall that affects deep south Texas through May 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 39.6 percent. This is an improvement from a previous
level of 37.8 percent three months ago. The Texas water share at
Falcon at this time last year was at 53.9 percent. The current Texas
water share at Amistad Reservoir has decreased during the past four
weeks to 80.8 percent. This is a lowering from a previous level of
83.9 percent three months ago. The Texas water share at Amistad at
this time last year was at 74.8 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.
