AS OF JULY 7 2009...THE U.S. DROUGHT MONITOR INDICATED THAT
EXCEPTIONAL DROUGHT CONDITIONS WERE AFFECTING PARTS OF JACKSON...
BURLESON...COLORADO...MATAGORDA AND WHARTON COUNTIES. EXTREME
DROUGHT CONDITIONS WERE AFFECTING PARTS OF BRAZOS...GRIMES...
MADISON...WALLER...WASHINGTON...HARRIS AND FORT BEND COUNTIES.
SEVERE DROUGHT CONDITIONS WERE AFFECTING PARTS OF TRINITY...
HOUSTON...WALKER...MONTGOMERY...LIBERTY...CHAMBERS...GALVESTON AND
SAN JACINTO COUNTIES. THE NEXT 5 TO 7 DAYS DON`T LOOK PROMISING FOR
RAIN SO DROUGHT CONDITIONS WILL LIKELY WORSEN.

FOR FURTHER CLARIFICATION...SEE EITHER (ALL LINKS IN LOWER CASE)
HTTP://WWW.DROUGHT.UNL.EDU/DM/DM_STATE.HTM?TX.S OR FOR THE ENTIRE
COUNTRY SEE...HTTP://WWW.DROUGHT.UNL.EDU/DM/MONITOR.HTML.

AGRICULTURAL IMPACTS...
THE LATEST SOIL MOISTURE ANOMALY GRAPHIC FROM THE CLIMATE PREDICTION
CENTER SHOWS EXCESSIVELY DRY SOIL CONDITIONS OVER ALL OF SOUTHEAST
TEXAS. THE JULY 7TH TEXAS A & M TEXAS CROP AND WEATHER REPORT
INDICATED THAT CATTLE PRODUCERS WERE AGGRESSIVELY CULLING COW HERDS
AND MARKETING CALVES EARLY. THE CONDITION OF CORN AND SORGHUM
CONTINUED TO DETERIORATE. POND LEVELS CONTINUE TO DROP. FOR MORE
INFORMATION...SEE HTTP://AGNEWS.TAMU.EDU (ALL LOWER CASE).

HYDROLOGIC IMPACTS...
RECENT RAINFALL HAS HELPED TO REPLENISH LAKE LIVINGSTON AND LAKE
HOUSTON BUT DRIER CONDITIONS OVER CENTRAL TEXAS HAS ALLOWED LAKE
LEVELS TO DROP AT LAKE SOMERVILLE AND LAKE TEXANA.

     WATERSHED                   CAPACITY

LAKE LIVINGSTON                  100 PERCENT
LAKE CONROE                       96 PERCENT
HOUSTON COUNTY LAKE               93 PERCENT
LAKE HOUSTON                     100 PERCENT
LAKE SOMERVILLE                   80 PERCENT
LAKE TEXANA                       64 PERCENT

FIRE DANGER IMPACTS...
A HIGH FIRE DANGER EXISTS OVER SOUTHEAST TEXAS. HIGH RELATIVE
HUMIDITY VALUES WILL ALLOW FOR SOME RECOVERY AT NIGHT BUT EXTREME
DAYTIME TEMPERATURES...AVERAGING 4 TO 6 DEGREES ABOVE NORMAL WILL
INCREASE THE FIRE WEATHER THREAT. DRY GROUND FUELS WILL ALSO
INCREASE THE THREAT FOR WILD FIRES.

AS OF JULY 9TH...RECENT RAINS HAVE HELP TO IMPROVE THE KEETCH-BYRAM
DROUGHT INDICES OVER PARTS OF SOUTHEAST TEXAS. THE KBDI WILL
INCREASE THIS WEEKEND AS TEMPERATURE SOAR TO NEAR 100 DEGREES AND RAIN
CHANCES DECLINE. BELOW IS A TABLE WITH KBDI VALUES (07/09/2009):

        600-700             500-600           400-500

(SEE THE LINK...ALL LOWER CASE HTTP://WEBGIS.TAMU.EDU/TFS/

RESTRICTIONS/ACTIONS...
ACCORDING TO THE TEXAS FOREST SERVICE WEB SITE ON JUNE 28 2009...
(HTTP://TFSFRP.TAMU.EDU/WILDFIRES/DECBAN.PNG)...A BURN BAN IS IN
EFFECT FOR THE FOLLOWING COUNTIES:

MADISON...WALKER...LIBERTY...CHAMBERS...MATAGORDA...HOUSTON...
BRAZORIA...HARRIS...AUSTIN...BRAZOS...POLK...SAN JACINTO...
WHARTON... MONTGOMERY...WALLER...AUSTIN...WASHINGTON...GRIMES...
JACKSON...TRINITY...FORT BEND...GALVESTON AND COLORADO COUNTIES.
CONDITIONS CONTINUE WILL DETERIORATE EVEN FURTHER THIS WEEKEND AND
EARLY NEXT WEEK.

WATER RESTRICTIONS ARE IN EFFECT FOR SOME COMMUNITIES INCLUDING
PEARLAND...THE WOODLANDS...CONROE...BAYOU VISTA...LEAGUE CITY...
SUGARLAND AND LA MARQUE.

RESIDENTS SHOULD REMAIN VIGILANT WHEN DOING ANY OUTDOOR ACTIVITIES
WHICH INVOLVE FIRE OR SPARKS...BY MAKING SURE WATER IS QUICKLY
AVAILABLE IF AN UNWANTED FIRE OR SMOLDERING BEGIN. FINALLY...
MOTORISTS SHOULD NOT DISCARD LIGHTED CIGARETTES FROM THEIR VEHICLES.

OUTLOOK...
A PERSISTENT AND STRONG UPPER LEVEL RIDGE OF HIGH PRESSURE WILL
GRADUALLY STRENGTHEN AND REMAIN ANCHORED OVER NORTHWEST TEXAS. THIS
WILL PROVIDE UNSEASONABLY WARM TEMPERATURES AND WILL SHUNT WEATHER
SYSTEMS TO THE EAST OF SOUTHEAST TEXAS. THERE IS A SLIGHT
POSSIBILITY THAT THE RIDGE COULD SHIFT FAR ENOUGH TO THE WEST TO
ALLOW A FEW STORMS TO CLIP THE EASTERN HALF OF THE REGION THIS
WEEKEND. THE OVERALL TREND IS FOR THE HEAT TO CONTINUE AND THE
DROUGHT TO WORSEN. FOR THOSE WHO RECEIVED RAIN THIS WEEK...CONSIDER
YOURSELVES LUCKY. FOR THOSE WHO DID NOT RECEIVE RAIN...IT APPEARS
THAT ANOTHER 5 TO 7 DAYS WILL PASS WITHOUT RAIN.

THE NEXT DROUGHT INFORMATION STATEMENT WILL BE BE ISSUED ON OR AROUND
JULY 16 2009.
