DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
200 PM CDT THU MAY 30 2013 /100 PM MDT THU MAY 30 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 28
MAY...SHOWS DROUGHT CONDITIONS CONTINUED TO WORSEN OVER THE PAST
MONTH OR SO IN SOUTHEAST NEW MEXICO AND WEST TEXAS. IN SOUTHEAST
NEW MEXICO...NORTHWEST EDDY AND LEA COUNTIES WERE IN EXCEPTIONAL
DROUGHT. THE REST OF THESE COUNTIES WERE IN EXTREME TO MODERATE
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...EXCEPTIONAL DROUGHT HAD CREPT INTO THE WESTERN LOW ROLLING
PLAINS...EXTENDING FROM PORTIONS OF GAINES COUNTY EAST THROUGH
SCURRY COUNTY. THE REST OF THE WESTERN LOW ROLLING PLAINS...AND THE
NORTHERN HALF OF THE PERMIAN BASIN WERE IN EXTREME DROUGHT. THE
REST OF WEST TEXAS RANGED FROM SEVERE DROUGHT TO ABNORMALLY DRY.
BREWSTER AND PECOS COUNTY FARED THE BEST...AT ABNORMALLY DRY.
RAINFALL OVER THE PAST MONTH HAS BEEN SCANT...WATER SHORTAGES
REMAIN...AND MANDATORY WATER USE RESTRICTIONS REMAIN IN PLACE IN
SOME LOCATIONS.
SUMMARY OF IMPACTS...
FIRE DANGER IMPACTS.
AS OF 30 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
29 MAY...THE KEETCH-BYRAM DROUGHT INDEX SHOWED VALUES RANGING FROM
NEAR 300 IN THE GUADALUPE MOUNTAINS TO NEAR 700 IN THE DAVIS
MOUNTAINS. 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 29 MAY BY THE
TEXAS A&M AGRICULTURE PROGRAM...IN FAR WEST TEXAS...THE REGION
RECEIVED FROM A TRACE TO OVER 3.5 INCHES OF RAIN.
GENERALLY...CONDITIONS REMAINED HOT...DRY...AND WINDY. COTTON
PRODUCERS CONTINUED PLANTING IN SOME AREAS. IN OTHERS...EARLY
PLANTED COTTON BEGAN TO EMERGE. DUE TO LACK OF MOISTURE...RANCHERS
CONTINUED TO PROVIDE SUPPLEMENTAL FEED TO CATTLE OR WERE FURTHER
THINNING HERDS. PECAN GROWERS WERE IRRIGATING AND FERTILIZING
ORCHARDS.
IN THE SOUTH PLAINS...SEVERAL COUNTIES REPORTED RAIN. BORDEN COUNTY
GOT FROM 3 TO 4 INCHES IN MOST AREAS. MITCHELL COUNTY RECEIVED FROM
1.5 TO 2 INCHES...AND SCURRY COUNTY FROM 0.2 TO 4.5 INCHES.
PRODUCERS REMAINED OPTIMISTIC DESPITE DRY CONDITIONS...AND COTTON
PLANTING WAS IN FULL SWING. DRYLAND FARMERS WILL NEED RAIN FOR
CROPS TO EVEN EMERGE. IN MANY AREAS...RANGELAND AND PASTURE STILL
NEEDED A SIGNIFICANT RAIN.
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. PORTIONS OF
THE WESTERN LOW ROLLING PLAINS ARE ALSO NEAR-NORMAL. 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 1.56 INCHES OF PRECIPITATION. NORMAL IS 4.11
INCHES.
CARLSBAD HAS HAD 1.01 INCHES OF PRECIPITATION. NORMAL IS AROUND
3.31 INCHES.
MARFA HAS HAD 1.37 INCHES OF PRECIPITATION. NORMAL IS AROUND 3.11
INCHES.
FORT STOCKTON HAS HAD 2.87 INCHES OF PRECIPITATION. NORMAL IS
AROUND 3.81 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 JUNE THROUGH AUGUST FOR WEST TEXAS AND SOUTHEAST
NEW MEXICO FORECASTS BELOW-NORMAL PRECIPITATION AND ABOVE-NORMAL
TEMPERATURES.
THE LATEST U.S. SEASONAL DROUGHT OUTLOOK...ISSUED 16 MAY BY THE
CPC...INDICATES DROUGHT CONDITIONS LIKELY TO PERSIST OR DEVELOP
ACROSS WEST TEXAS AND SOUTHEAST NEW MEXICO.
