DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
1200 PM CDT MON MAY 13 2013 /1100 AM MDT MON MAY 13 2013/
...DROUGHT INFORMATION STATEMENT FOR WEST TEXAS AND SOUTHEAST NEW
MEXICO...
SYNOPSIS...
THE U.S. DROUGHT MONITOR (USDM)...ISSUED IN PARTNERSHIP BETWEEN THE
NATIONAL DROUGHT MITIGATION CENTER...USDA...AND NWS ON 7 MAY...SHOWS
DROUGHT CONDITIONS CONTINUED TO DETERIORATE OVER THE PAST MONTH OR
SO IN SOUTHEAST NEW MEXICO AND WEST TEXAS. IN SOUTHEAST NEW
MEXICO...NORTHWEST EDDY AND LEA COUNTIES HAD WORSENED TO EXCEPTIONAL
DROUGHT. MOST OF THE REST OF THE COUNTIES WERE IN EXTREME TO SEVERE
DROUGHT...AND SOUTHEAST EDDY AND SOUTH LEA COUNTIES WERE IN MODERATE
DROUGHT TO ABNORMALLY DRY. IMPACTS OF EXTREME AND SEVERE DROUGHT
CONDITIONS INCLUDE CROP OR PASTURE LOSSES LIKELY...WATER SHORTAGES
COMMON...AND WATER RESTRICTIONS IMPOSED. IMPACTS OF MODERATE
DROUGHT CONDITIONS INCLUDE SOME DAMAGE TO CROPS AND PASTURES. IN
WEST TEXAS...EXCEPTIONAL DROUGHT CONDITIONS HAD DEVELOPED IN
PORTIONS OF GLASSCOCK AND HOWARD COUNTIES. MOST OF THE REST OF THE
WESTERN LOW ROLLING PLAINS AND PERMIAN BASIN WERE IN EXTREME
DROUGHT. MOST OF THE REST OF WEST TEXAS WAS IN SEVERE OR MODERATE
DROUGHT. MOST OF LOVING COUNTY AND THE BIG BEND REGION WERE
ABNORMALLY DRY.
THIS IS THE FIRST TIME SINCE EARLY MAY 2012 THAT EXCEPTIONAL DROUGHT
HAS RETURNED TO WEST TEXAS AND SOUTHEAST NEW MEXICO.
RAINFALL OVER THE PAST 30 DAYS HAS BEEN MEAGER...AND SO WATER
SHORTAGES REMAIN...AND MANDATORY WATER USE RESTRICTIONS REMAIN IN
PLACE IN SOME LOCATIONS.
SUMMARY OF IMPACTS...
FIRE DANGER IMPACTS.
AS OF 10 MAY...ALL OF WEST TEXAS REMAINS UNDER AN OUTDOOR BURN BAN
EXCEPT DAWSON...ECTOR...MIDLAND...AND REEVES COUNTIES.
THE TEXAS FOREST SERVICE USES THE KEETCH-BYRAM DROUGHT INDEX (KBDI)
AS A SYSTEM FOR RELATING CURRENT AND RECENT WEATHER CONDITIONS TO
POTENTIAL OR EXPECTED FIRE BEHAVIOR. IT IS A NUMERICAL INDEX
CALCULATED DAILY. 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 0 TO 800...WITH 0
REPRESENTING A SATURATED SOIL AND 800 A COMPLETELY DRY SOIL. AS OF
12 MAY...THE KEETCH-BYRAM DROUGHT INDEX SHOWED VALUES RANGING FROM
NEAR 300 IN THE GUADALUPE MOUNTAINS TO NEAR 700 IN THE DAVIS
MOUNTAINS AND PORTIONS OF THE SOUTHEAST NEW MEXICO PLAINS. THE 400
TO 600 RANGE IS TYPICAL OF LATE SUMMER AND EARLY FALL. IN THIS
RANGE...LOWER LITTER AND DUFF LAYERS CONTRIBUTE TO FIRE INTENSITY
AND WILL BURN ACTIVELY. NOTE THAT FIRE DANGER CAN CHANGE QUICKLY
FROM DAY TO DAY AS WINDS AND RELATIVE HUMIDITY VARY. THE TEXAS
FOREST SERVICE ADVISES TO WATCH OUT FOR KEY CRITICAL WEATHER
THRESHOLDS OF WINDS ABOVE 15 MPH AND RELATIVE HUMIDITY BELOW 25
PERCENT. WHEN THESE THRESHOLDS ARE MET OR EXCEEDED...FIRE DANGER
WILL BE ELEVATED.
AGRICULTURAL IMPACTS...
ACCORDING TO THE TEXAS CROP WEATHER REPORT ISSUED 7 MAY BY THE TEXAS
A&M AGRICULTURE PROGRAM...IN FAR WEST TEXAS...A COLD FRONT BROUGHT
TRACES OF MOISTURE TO PARTS OF THE AREA. ON 3 MAY...MOST OF THE
AREA RECORDED LIGHT FREEZING CONDITIONS. THE AREA IS ON ALERT FOR
WILDFIRE DUE TO DRY CONDITIONS AND HIGH WINDS. LIVESTOCK PRODUCERS
CONTINUED TO PROVIDE SUPPLEMENTAL FEED FOR CATTLE. SOME RANCHERS
WERE STARTING TO SELL CATTLE DUE TO LACK OF GRAZING. PASTURES
CONTINUED BE STRESSED DUE TO THE DROUGHT.
IN THE SOUTH PLAINS...MITCHELL COUNTY WAS LUCKY TO RECEIVE SOME
RAIN...THOUGH ACCUMULATIONS WERE IN THE TENTHS OF AN INCH. OTHER
COUNTIES REMAINED DRY. ANOTHER COLD FRONT BARRELED THROUGH THE
REGION 2-3 MAY...WITH DAMAGING WINDS OF UP TO 60 MPH...FOLLOWED BY
YET ANOTHER HARD FREEZE ON THE MORNING OF 3 MAY. WITH ALL THE LATE
FREEZES...MOST OF THE WHEAT IN THE DISTRICT WILL BE CUT FOR HAY
RATHER THAN HARVESTED. PRODUCERS CONTINUED TO PREPARE FOR SPRING
PLANTING...AND MOST ARE PRE-WATERING FIELDS. SOME PRODUCERS
EXPECTED TO BEGIN PLANTING COTTON WITHIN THE NEXT TWO WEEKS. THOUGH
SOIL TEMPERATURES WERE LOW...A COUPLE OF PRODUCERS PLANTED EARLY TO
ENSURE THE PRE-WATERING MOISTURE WAS NOT LOST. HOWEVER...WITH THE
FREEZES STILL OCCURRING...SOME WERE WAITING FOR THE SOIL TEMPERATURE
TO BECOME WARMER AND STAY CONSISTENT BEFORE PLANTING. RANGELAND AND
PASTURES STILL NEEDED RAIN. LIVESTOCK REMAINED MOSTLY IN FAIR
CONDITION...BUT SOME HERDS WERE BEING CULLED DUE TO THE CONTINUING
DROUGHT. STOCK-TANK WATER LEVELS WERE LOW.
CLIMATE SUMMARY...
RAINFALL FOR THE YEAR IS NEAR-NORMAL FROM A SWATH OF LAND EXTENDING
FROM SOUTHERN LEA COUNTY ALONG THE PECOS RIVER TO FORT
STOCKTON...AND IN ISOLATED POCKETS IN BREWSTER COUNTY. EVERYWHERE
ELSE IN WEST TEXAS AND SOUTHEAST NEW MEXICO IS BELOW NORMAL. EDDY
COUNTY...CULBERSON COUNTY...WEST JEFF DAVIS COUNTY...AND WESTERN
PRESIDIO COUNTY FARED THE WORST...WITH SOME LOCATIONS HAVING
RECEIVED JUST 5 PERCENT OR LESS OF NORMAL SINCE THE BEGINNING OF THE
YEAR.
SINCE 1 JANUARY...THE FOLLOWING PRECIPITATION AMOUNTS WERE REPORTED:
MIDLAND HAS RECEIVED 1.54 INCHES OF PRECIPITATION. NORMAL IS 2.98
INCHES.
CARLSBAD HAS HAD 0.90 INCHES OF PRECIPITATION. NORMAL IS AROUND
2.39 INCHES.
MARFA HAS HAD 1.17 INCHES OF PRECIPITATION. NORMAL IS AROUND 2.41
INCHES.
FORT STOCKTON HAS HAD 2.43 INCHES OF PRECIPITATION. NORMAL IS
AROUND 2.73 INCHES.
PRECIPITATION/TEMPERATURE OUTLOOK...
ACCORDING TO THE CLIMATE PREDICTION CENTER...OR CPC...ENSO-NEUTRAL
CONDITIONS ARE EXPECTED TO CONTINUE THROUGH SUMMER.
THE CPC OUTLOOK FOR MAY THROUGH JULY FOR WEST TEXAS AND SOUTHEAST
NEW MEXICO FORECASTS BELOW-NORMAL TO NORMAL PRECIPITATION AND
ABOVE-NORMAL TEMPERATURES.
THE LATEST U.S. SEASONAL DROUGHT OUTLOOK...ISSUED 2 MAY BY THE
CLIMATE PREDICTION CENTER...INDICATES DROUGHT CONDITIONS LIKELY TO
PERSIST OR DEVELOP ACROSS WEST TEXAS AND SOUTHEAST NEW MEXICO.
