DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX
100 PM CDT THU APR 24 2014

...DROUGHT CONDITIONS REMAIN UNCHANGED THIS WEEK...

SYNOPSIS...

APRIL HAS SEEN SOME LARGE SWINGS IN TEMPERATURES ACROSS SOUTH
CENTRAL TEXAS AND SEVERAL RAINFALL EVENTS. FOR THE MOST PART
RAINFALL HAS BEEN SPOTTY AND LESS THAN ONE-HALF INCH...BUT A FEW
LOCATIONS HAVE SEEN RAINFALL OF ONE TO TWO INCHES. PORTIONS OF THE
HILL COUNTRY HAVE SEEN THE HEAVIER RAINFALL AMOUNTS AND ISOLATED
LOCATIONS ACROSS THE RIO GRANDE PLAINS. BOTH THESE AREAS ARE
CURRENTLY IN SEVERE TO EXTREME DROUGHT. SEVERAL OF THE RAINFALL
EVENTS HAVE PRODUCE SEVERE WEATHER...WITH HAIL GREATER THAN ONE
INCH IN DIAMETER AND WINDS GREATER THAN 58 MPH. FOR THE MONTH TO
DATE MOST LOCATIONS HAVE SEEN LESS THAN ONE INCH OF RAINFALL. OVER
THE RIO GRANDE PLAINS MANY LOCATIONS HAVE SEE NO RAINFALL OR ONLY
A FEW HUNDREDTHS OF AN INCH SO FAR IN APRIL...AND LESS THAN A HALF
INCH SINCE JANUARY 1ST. THE NEXT SEVERAL DAYS WILL SEE
TEMPERATURES ABOVE LATE APRIL AVERAGES. THERE WILL BE A COUPLE OF
CHANCES FOR AT LEAST ISOLATED SHOWERS AND THUNDERSTORMS. SHORT
TERM DROUGHT IMPACTS REMAIN AT A MINIMUM IN MANY LOCATIONS...BUT
WILL GET WORSE IF DRIER CONDITIONS CONTINUE. CURRENTLY THE MAIN
SHORT TERM IMPACTS ARE MANY LOCATIONS HAVE WATER RESTRICTIONS IN
PLACE. FIRE WEATHER CONCERNS ARE INCREASING DUE TO MAINLY LIGHT
RAINFALL AMOUNTS...GUSTY WINDS AND LOW HUMIDITIES THAT QUICKLY
DRY THE FUELS. LONG TERM IMPACTS CONTINUE SINCE WE HAVE BEEN IN A
MULTIPLE YEAR DROUGHT. RIVERS...LAKES...RESERVOIRS AND AQUIFERS
ARE VERY LOW AND WILL REMAIN THAT WAY UNLESS WE CONTINUE TO SEE
FREQUENT RAINFALL EVENTS.

THE CLIMATE PREDICTION CENTER (CPC) IS FORECASTING THE ENSO (EL
NINO SOUTHERN OSCILLATION) NEUTRAL PATTERN TO CONTINUE INTO
SUMMER 2014. THE CLIMATE PREDICTION CENTER HAS ISSUED AN EL NINO
WATCH...SAYING THERE IS A 50 PERCENT OR GREATER CHANCE AN EL NINO
EVENT WILL DEVELOP IN THE SUMMER OR EARLY FALL. EVEN THOUGH LA
NINA AND EL NINO EVENTS HAVE SIGNIFICANT IMPACTS ACROSS THE
REGION...OTHER CIRCULATIONS ACROSS THE GLOBE HELP DRIVE WEATHER
PATTERNS TOO... SO WE SHOULD NOT JUST BE LOOKING AT ONE
PATTERN...BUT OTHERS AS WELL TO POTENTIALLY PROVIDE RAINFALL FOR
THE REGION.

THE US DROUGHT MONITOR (USDM) VALID APRIL 22ND AND ISSUED ON APRIL
24TH INDICATED DROUGHT CONDITIONS HAVE REMAINED UNCHANGED OVER
THE PAST WEEK ACROSS SOUTH CENTRAL TEXAS. ABNORMALLY DRY (D0) TO
EXTREME DROUGHT (D3) CONDITIONS WERE PRESENT ACROSS SOUTH CENTRAL
TEXAS. MOST LOCATIONS ARE CURRENTLY IN MODERATE DROUGHT (D1) TO
SEVERE DROUGHT (D2) STATUS. THERE CONTINUED TO BE AREAS OF EXTREME
DROUGHT (D3) ACROSS THE RIO GRANDE PLAINS AND PORTIONS THE HILL
COUNTRY...MAINLY IN GILLESPIE...KERR... BANDERA...MEDINA AND VAL
VERDE COUNTIES.

CURRENTLY 69 PERCENT OF THE STATE IS IN MODERATE DROUGHT (D1) TO
EXCEPTIONAL DROUGHT (D4) AND 13 PERCENT OF THE STATE IS IN
EXCEPTIONAL (D4) DROUGHT STATUS.

SUMMARY OF IMPACTS...

FIRE DANGER IMPACTS...

FIRE DANGER WAS MODERATE TO HIGH ACROSS THE AREA. IF WETTING
RAINFALL IS NOT OBSERVED THEN FIRE DANGER THREATS WILL INCREASE.

COUNTIES IN SOUTH CENTRAL TEXAS. THE COUNTIES WITH ESTABLISHED
OUTDOOR BURN BANS INCLUDE:

ATASCOSA
BEXAR

THE APRIL 24TH COUNTY KEETCH-BYRAM DROUGHT INDEX (KBDI) SHOWED THE
FOLLOWING KBDI VALUES:

THE TEXAS FOREST SERVICE USES THE KBDI AS A MEANS FOR RELATING
CURRENT AND RECENT WEATHER CONDITIONS TO POTENTIAL OR EXPECTED
FIRE BEHAVIOR. THE KBDI IS A NUMERICAL INDEX CALCULATED DAILY FOR
EACH COUNTY. EACH NUMBER IS AN ESTIMATE OF THE AMOUNT OF
PRECIPITATION...IN HUNDREDTHS OF AN INCH...NEEDED TO BRING THE
SOIL BACK TO SATURATION. THE INDEX RANGES FROM ZERO TO 800...WITH
ZERO REPRESENTING A SATURATED SOIL AND 800 A COMPLETELY DRY SOIL.
REMEMBER...THAT FIRE DANGER CAN CHANGE QUICKLY FROM ONE DAY TO
ANOTHER AS WINDS AND RELATIVE HUMIDITY VARY.

AGRICULTURAL IMPACTS...

THE TEXAS CROP AND WEATHER REPORT ISSUED BY TEXAS A AND M
AGRICULTURAL ON APRIL 22 2014 INDICATED...THERE WERE A FEW LIGHT
SHOWERS ACROSS THE DISTRICT...BUT GENERALLY THE REGION REMAINED
DRY. SOME COUNTIES REPORTED SUB-FREEZING TEMPERATURES HAD DAMAGED
YOUNG CORN AND SORGHUM. HOWEVER...PEACHES...OTHER FRUIT AND SELECT
FIELD CROPS CAME THROUGH THE FREEZE WITH ONLY ISOLATED...LIGHT
DAMAGE TO NEW LEAF TIPS. IN THE EASTERN PARTS OF THE
DISTRICT...LIVESTOCK REMAINED IN GOOD CONDITION WITH GOOD GRAZING
AVAILABLE. IN THE WESTERN COUNTIES...GRASS GROWTH WAS
MINIMAL...AND SUPPLEMENTAL FEEDING OF LIVESTOCK REMAINED NECESSARY.


CLIMATE SUMMARY...

THE NEXT SEVERAL DAYS ARE EXPECTED TO SEE ABOVE AVERAGE TEMPERATURES
ALONG WITH A COUPLE OF CHANCES FOR ISOLATED TO SCATTERED SHOWERS
AND THUNDERSTORMS. BY TUESDAY, APRIL 29TH A COLD FRONT WILL USHER
IN COOLER TEMPERATURES.

PRECIPITATION FROM JANUARY 1, 2014 TO MIDNIGHT APRIL 23, 2014 AND
DEPARTURE FROM NORMAL:

                   2014        NORMAL     DEPARTURE     PERCENT

PRECIPITATION/TEMPERATURE OUTLOOK...

THE OUTLOOK FOR THE NEXT SEVERAL DAYS INDICATES A FAIRLY WARM AND
DRY. THERE WILL BE AN OPPORTUNITY OR TWO FOR SOME ISOLATED
RAINFALL ACROSS THE REGION.

THE LATEST CLIMATE PREDICTION CENTER (CPC) 8 TO 14 DAY OUTLOOK
ISSUED APRIL 23 AND VALID MAY 1 THROUGH MAY 7 WAS INDICATING
VERY STRONG SIGNALS FOR BELOW AVERAGE TEMPERATURES AND RAINFALL.

THE LONGER RANGE OUTLOOK FOR MAY 2014 THROUGH JULY 2014...
CREATED ON APRIL 17TH WAS INDICATING STRONGER SIGNALS FOR ABOVE
AVERAGE TEMPERATURES. THERE WERE NO STRONG SIGNALS FOR
AVERAGE...ABOVE AVERAGE OR BELOW AVERAGE PRECIPITATION...WHICH
INDICATES PRECIPITATION WILL MOST LIKELY BE NEAR AVERAGE FOR THE
PERIOD. THESE OUTLOOKS WILL BE UPDATED AGAIN ON MAY 15 2014.

HYDROLOGIC SUMMARY AND OUTLOOK...

SHORT TERM RAINFALL DEFICITS ARE INCREASING DUE TO BELOW AVERAGE
PRECIPITATION SINCE DECEMBER. LAKE LEVELS CONTINUE TO FALL
SLOWLY. AS TEMPERATURES CONTINUE TO INCREASE DURING THE SPRING AND
INTO SUMMER THE EVAPORATION RATES WILL CONTINUE TO INCREASE.

LONG TERM DROUGHT IMPACTS TO AREA AQUIFERS...LAKES AND RESERVOIRS
CONTINUE.

THE 7 DAY STREAM FLOW AVERAGES WERE MUCH BELOW NORMAL (LESS THAN
10 PERCENT) ACROSS THE GUADALUPE...MEDINA...FRIO AND NUECES RIVER
BASINS. THE SAN ANTONIO RIVER BASIN WAS REPORTING BELOW NORMAL
(10-24 PERCENT) FLOWS. NORMAL (25-75 PERCENT) FLOWS WERE SEEN
ACROSS THE RIO GRANDE BASIN. THE COLORADO BASIN WAS REPORTING
NORMAL FLOWS (27-75 PERCENT) ACROSS THE MIDDLE PORTION OF THE
BASIN AND MUCH BELOW NORMAL (LESS THAN 10 PERCENT) FLOWS OVER THE
REMAINDER OF THE BASIN.

RESERVOIR CONDITIONS AS OF APRIL 24TH...

LAKES...RIVERS AND RESERVOIRS REMAIN WELL BELOW NORMAL POOL
ELEVATIONS.

BELOW IS A LIST OF RESERVOIRS WITH THE LATEST ELEVATIONS AND
NORMAL POOLS.

RESTRICTIONS...

THE SAN ANTONIO WATER SYSTEM (SAWS) IS CURRENTLY IN STAGE 2 WATER
RESTRICTIONS. SAWS PLANS TO RETAIN THE STAGE 2 RESTRICTIONS
DESPITE PERIODS WHEN THE DECLINE OF THE EDWARDS AQUIFER 10-DAY
AVERAGE FALLS TO BELOW 640 FEET WHICH IS THE THRESHOLD FOR STAGE
3 RESTRICTIONS.

THE EDWARDS AQUIFER AUTHORITY HAS DECLARED STAGE 3 RESTRICTIONS
WHICH MEANS THE LARGE USERS OF WATER MUST REDUCE THEIR PUMPING BY
35 PERCENT.

LATEST READINGS FROM THE EDWARDS AQUIFER:

 CURRENT    APRIL    DEPARTURE FROM    2013 LEVEL   DEPARTURE
  LEVEL    AVERAGE     APRIL AVG      ON THIS DATE  FROM 2013

 637.9 FT  667.8 FT    -29.9 FT         645.6 FT     -7.7 FT

MANY COMMUNITIES ACROSS SOUTH CENTRAL TEXAS CONTINUE TO HAVE
WATER RESTRICTIONS IN PLACE TO DUE LACK OF CONSISTENT RAINFALL.
STRICTER RESTRICTIONS COULD BE IMPLEMENTED AT ANY TIME IF THE
DRIER THAN NORMAL CONDITIONS PERSIST.

THE BARTON SPRINGS EDWARDS AQUIFER CONSERVATION DISTRICT IS
CURRENTLY IN NON-DROUGHT. DROUGHT THRESHOLDS COULD BE EXCEEDED
AND DROUGHT DECLARATIONS MAY BE IMPLEMENTED SOON.

LOCATIONS THAT DO NOT CURRENTLY HAVE MANDATORY RESTRICTIONS
CONTINUE TO STRONGLY PROMOTE YEAR ROUND WATER CONSERVATION.
