DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE SAN ANGELO TX
329 PM CST Fri Feb 9 2018

...Severe drought conditions have expanded into west central
Texas...

Synopsis...

The latest U.S Drought Monitor (USDM), released on February 8th,
indicates that severe drought (D2) conditions have expanded into
the Heartland, northwestern Hill Country, northern Edwards
Plateau, and the Big Country.

Summary of Impacts...

Fire Weather Impacts...

Warmer than normal temperatures combined with periods of dry and
gusty winds enhance critical fire weather conditions. Fire danger
can change from day to day as wind and relative humidity vary. The
Texas Forest Service advises to watch out for key weather
thresholds of winds above 15 mph and relative humidity values
below 25 percent. When these thresholds are exceeded, expect the
fire danger will be elevated.

As of February 9th, countywide outdoor burn bans were supported in
Throckmorton, Nolan, Taylor, Callahan, Coke, Coleman, Brown, Tom
Green, Concho, McCulloch, San Saba, Schleicher, Menard, Mason,
Sutton, and Kimble counties.

Agricultural Impacts...

Subsoil moisture is very poor across the region. This, along with the
lack of rain, has severely impacted winter wheat. Cattle are being
fed are a regular basis given the lack of available winter grass.
Many stock tanks are totally dry or very low.

Climate Summary...

Very dry conditions have occurred since the beginning of the year.
This combined with the fact that the 2017 calendar year ended
with a precipitation deficit, has resulted in the drought
expanding into the region.

Since the beginning of January, 2018, the following precipitation
amounts have been recorded:

Abilene received only a trace of rainfall, which is 1.36 inches
below normal.

San Angelo received 0.03 inches of rainfall, which is 1.23 inches
below normal.

Junction received 0.06 inches of rainfall, which is 1.23 inches
below normal.

Precipitation/Temperature Outlook...

According to the Climate Predication Center (CPC), La Nina will
continue over the next several months, before likely
transitioning into ENSO-neutral. Therefore, this will be the main
driver in weather patterns over the next several months. Overall,
normal to above normal temperatures and below normal
precipitation are expected for the remainder of winter and early
spring. If indeed some weakening of La Nina occurs, equal chances
for dry, normal, and wet conditions along with continuing above
normal temperatures will be expected for late spring.

The latest U.S. Seasonal Drought Outlook for January 18 through
April 30 (issued by the CPC), shows that drought conditions will
likely persist and even expand further across west central Texas.

Hydrologic Summary And Outlook...

According to the U.S. Geological Survey (USGS), gaged streamflows
across most of west central Texas are well below normal for this
time of year.
