...DROUGHT INFORMATION STATEMENT...

...DROUGHT HAS REACHED EXCEPTIONAL LEVELS IN SOUTHEAST TEXAS...

SYNOPSIS...
A FAST UPPER LEVEL FLOW HAS HELPED TO KEEP STORM SYSTEMS WEAK AND
MOISTURE LEVELS LOW OVER THE PAST TEN DAYS ACROSS SOUTHEAST TEXAS.
AN UPPER LEVEL DISTURBANCE AND A COLD FRONT BROUGHT SOME HIT AND
MISS SHOWERS AND THUNDERSTORMS THIS PAST TUESDAY NIGHT...BUT THE
PRECIPITATION WAS MORE MISS THAN HIT WITH THE HEAVIEST RAINFALL
BEING 0.73 INCHES IN KINGWOOD. MOST LOCATIONS THAT HAD RAINFALL
RECEIVED JUST A FEW HUNDREDTHS OF AN INCH. THE LAST SIGNIFICANT RAIN
EVENT TO AFFECT SOUTHEAST TEXAS WAS ON MARCH 14TH.

FROM FEBRUARY 1ST TO APRIL 7TH...THE CITY OF HOUSTON (IAH) HAS
RECEIVED ONLY 1.48 INCHES OF RAIN...COLLEGE STATION (CLL) 1.30
INCHES...HOUSTON HOBBY (HOU) 1.12 INCHES...AND GALVESTON (GLS) 3.48
INCHES.

EVEN WITH THE RECENT LIGHT RAINS...THE DROUGHT HAS CONTINUED TO
WORSEN ACROSS ALL OF SOUTHEAST TEXAS. IN CONTEXT...AS OF APRIL 5TH
DROUGHT BLANKETED ALL OF TEXAS. THAT HAS NOT HAPPENED TO THE ENTIRE
STATE SINCE MARCH OF 2009. THE U.S. DROUGHT MONITOR SHOWED MUCH OF
THE NORTHERN THIRD OF SOUTHEAST TEXAS IN EXCEPTIONAL DROUGHT OR D-4.
THE AREA OF EXTREME DROUGHT D-3 CONDITIONS HAS EXPANDED SOUTH AND
NOW COVERS MOST OF THE REMAINDER OF SOUTHEAST TEXAS...EXCLUDING THE
IMMEDIATE COAST WHERE THERE WAS A SEVERE DROUGHT. THERE ARE 23
COUNTIES THAT COMPRISE AN AREA REFERRED TO AS SOUTHEAST TEXAS.

DROUGHT CONDITIONS WILL LIKELY REMAIN THE SAME OR WORSEN OVER THE
NEXT TEN DAYS. ABOVE NORMAL AFTERNOON TEMPERATURES WILL LIKELY
CONTINUE. HOWEVER...SLIGHTLY COOLER CONDITIONS WILL PERHAPS RESULT
IN NEAR NORMAL TEMPERATURES AFTER A PACIFIC FRONT MOVES THROUGH THE
AREA EARLY MONDAY AND THEN AFTER ANOTHER COLD FRONTAL PASSAGE ON
THURSDAY.

BELOW IS A LIST OF COUNTIES AND THEIR RESPECTIVE CLASSIFICATION AS
DESIGNATED BY THE U.S. DROUGHT MONITOR AS OF MARCH 29TH.

CLIMATE SUMMARY...
CONDITIONS HAVE BEEN QUITE DRY SINCE OCTOBER 2008. THE LAST TEN
WEEKS HAVE CONTINUED THIS TREND AND THE LONG RANGE OUTLOOK INDICATES
DRIER THAN NORMAL CONDITIONS TO PERSIST THROUGH JUNE. THE 6 TO 10
DAY AND 8 TO 14 DAY PRECIPITATION PROBABILITY INDICATES A DRY
SIGNAL SO IT APPEARS THAT LITTLE RELIEF IS IN THE OFFING. WARMER
THAN NORMAL TEMPERATURES SHOULD CONTINUE THROUGH THE END OF THE
MONTH AND THIS TREND WILL EXTEND AND MAY INTENSIFY THROUGH JUNE.

THE DRY PERIOD FOR SOUTHEAST TEXAS INTENSIFIED DURING THE AUTUMN OF
2010 AS A STRONG LA NINA PHASE DEVELOPED. ALTHOUGH THERE WAS A BRIEF
WINDOW WITH ABOVE NORMAL RAINFALL DURING LATE DECEMBER AND EARLY
JANUARY...THE OVERALL TREND SINCE OCTOBER HAS BEEN VERY DRY WITH
BELOW NORMAL RAINFALL. COLLEGE STATION HAS HAD ITS DRIEST PERIOD OF
RECORD BETWEEN OCTOBER AND MARCH WHEN ONLY 6.00 INCHES OF RAINFALL
WAS RECORDED. THIS IS 31.3 PERCENT OF NORMAL. THE NORMAL RAINFALL AT
COLLEGE STATION FOR OCTOBER 1 THROUGH MARCH 31 IS 19.17 INCHES. HERE
IS A LIST OF THE DRIEST PERIODS OF RECORD FOR OCTOBER 1ST THROUGH
MARCH 31ST.

SUMMARY OF IMPACTS...

AGRICULTURAL IMPACTS...
AGRICULTURAL CONDITIONS ARE DETERIORATING! THE REGION REMAINS VERY
DRY. PLANTING OF NEW FORAGES WERE PUT ON HOLD DUE TO A LACK OF
MOISTURE. STOCK WATER TANKS AND POND LEVELS WERE DROPPING
DRASTICALLY WITH SOME NEAR RECORD LOW LEVELS. WHEAT WAS NOT LOOKING
GOOD. RICE PLANTING CONTINUED DESPITE THE DRY CONDITIONS. TOPSOIL
MOISTURE DRIED OUT AND MANY FARMERS STOPPED PLANTING COTTON AND WERE
WAITING FOR RAIN BEFORE RESUMING.

RANGE LAND AND PASTURES CONTINUE TO DETERIORATE. LIVESTOCK PRODUCERS
WERE SUPPLEMENTING HAY TO MAKE UP FOR THE LACK OF GRAZING.

FOR MORE INFORMATION...SEE HTTP://AGRILIFE.ORG/TODAY (ALL LOWER
CASE).

FIRE DANGER IMPACTS...
100 HOUR FUEL MOISTURE WAS CRITICALLY DRY...GENERALLY LESS THAN 10
PERCENT FOR ALL AREAS OF SOUTHEAST TEXAS! SOME AREAS OF FROM HOUSTON
TO COLDSPRING TO MADISONVILLE TO NEAR BRENHAM WERE AT 4 PERCENT OR
LESS! THIS IS IS IN THE DRIEST 2-10 PERCENT OF RECORDS FOR THE
REGION. HIGH FIRE DANGER IS EXPECTED ACROSS SOUTHEAST TEXAS THIS
WEEKEND AND MAY RETURN AFTER THE COLD FRONT ON MONDAY. LARGE
WILDFIRES HAVE BURNED LARGE TRACTS OF LAND IN THE LAST 7 DAYS ACROSS
PARTS OF TEXAS.

UNSEASONABLY WARM TEMPERATURES AND LESS THAN NORMAL RAINFALL HAS
HELPED TO RAISE KEETCH-BYRAM DROUGHT INDICES ACROSS SOUTHEAST TEXAS.
VALUES BETWEEN 700 AND 800 ARE CRITICAL AND EXTREMELY DANGEROUS.
BELOW IS A TABLE WITH KBDI VALUES (4/08/2011).
