DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
1200 PM CDT THU APR 25 2013 /1100 AM MDT THU APR 25 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 16
APRIL...SHOWS THAT DROUGHT CONDITIONS HAVE SLOWLY CONTINUED TO
DETERIORATE OVER THE PAST MONTH OR SO IN SOUTHEAST NEW MEXICO AND
WEST TEXAS. IN SOUTHEAST NEW MEXICO...EXTREME NORTHWEST EDDY AND
LEA COUNTIES WERE IN EXTREME DROUGHT. MOST OF THE REST OF THE
COUNTIES WERE IN SEVERE DROUGHT...AND SOUTHEAST EDDY AND SOUTH LEA
COUNTIES WERE IN MODERATE DROUGHT TO NO DROUGHT. 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...EXTREME DROUGHT HAS PERSISTED OR
DEVELOPED IN PORTIONS OF
SCURRY...MITCHELL...GLASSCOCK...REAGAN...AND TERRELL COUNTIES.
WESTERN CULBERSON...JEFF DAVIS...AND NORTHWEST PRESIDIO COUNTIES
WERE IN SEVERE DROUGHT...AS WERE MOST OF THE WESTERN LOW ROLLING
PLAINS...PERMIAN BASIN...AND TERRELL COUNTY. THE REST OF WEST TEXAS
WAS IN MODERATE DROUGHT TO ABNORMALLY DRY.
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 23 APRIL...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
24 APRIL...THE KEETCH-BYRAM DROUGHT INDEX SHOWED VALUES RANGING FROM
NEAR 300 IN THE GUADALUPE MOUNTAINS TO NEAR 700 IN AREAS FURTHER
EAST. 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 23 APRIL BY THE
TEXAS A&M AGRICULTURE PROGRAM...IN FAR WEST TEXAS...HIGHS RANGED
FROM THE MID 70S TO UPPER 80S. DRY...WINDY CONDITIONS MEANT
RED-FLAG WARNINGS FOR WILDFIRE REMAINED IN EFFECT FOR MOST OF THE
AREA. PASTURES SUFFERED AS THE DROUGHT BECAME MORE SEVERE.
MESQUITE...SAND SAGE...AND SHIN OAK WERE GREENING UP. ANNUAL WEEDS
AND WILDFLOWERS WERE SPROUTING IN BAR DITCHES AND LOW AREAS. COTTON
GROWERS CONTINUED PLANTING PREPARATIONS.
IN THE SOUTH PLAINS...CONTINUED SEVERE DROUGHT WITH HIGH WINDS AND
THREE LATE SEASON FREEZES DAMAGED DEVELOPING WHEAT. IN SOME
COUNTIES...THE FREEZE DAMAGE WAS SEVERE...WHILE IN OTHERS IT WAS
SURPRISINGLY BEEN LESS THAN EXPECTED. MOST WHEAT WILL EITHER BE CUT
FOR HAY...GRAZED...OR KILLED...AND PUT IN COTTON OR SORGHUM. SOME
COUNTIES REPORTED RUSSIAN WHEAT APHIDS IN FIELDS. PRODUCERS BEGAN
PRE-PLANT IRRIGATION ALONG WITH FERTILIZER AND HERBICIDE
APPLICATIONS. TEMPERATURES WERE ALL ACROSS THE BOARD WITH HIGHS ONE
DAY IN THE 90S AND LOWS THE NEXT INTO THE 20S. THERE WAS NO
MEASURABLE PRECIPITATION. RANGELAND AND PASTURES WERE IN FAIR
CONDITION...AS WERE LIVESTOCK WITH SUPPLEMENTAL FEEDING ON COOL/COLD
DAYS.
CLIMATE SUMMARY...
RAINFALL FOR THE YEAR IS AT OR ABOVE 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 1.53 INCHES OF PRECIPITATION. NORMAL IS 2.38
INCHES.
CARLSBAD HAS HAD 0.90 INCHES OF PRECIPITATION. NORMAL IS AROUND
1.85 INCHES.
MARFA HAS HAD 0.77 INCHES OF PRECIPITATION. NORMAL IS AROUND 1.80
INCHES.
FORT STOCKTON HAS HAD 2.19 INCHES OF PRECIPITATION. NORMAL IS
AROUND 2.44 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 APRIL THROUGH JUNE 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 21 MARCH BY THE
CLIMATE PREDICTION CENTER...INDICATES DROUGHT CONDITIONS LIKELY TO
PERSIST OR INTENSIFY ACROSS WEST TEXAS AND SOUTHEAST NEW MEXICO.
