SPECIAL WEATHER STATEMENT
Issue Date: 500 AM CDT WED SEP 8 2010
Expiration: 100 PM CDT WED SEP 08 2010

FORECASTERS CONTINUE TO WATCH THE REMNANTS OF HERMINE AS IT MOVES
TOWARD WESTERN NORTH TEXAS AND OKLAHOMA. THE BRUNT TO THE STORM IS
EXPECTED THIS AFTERNOON THROUGH TONIGHT...WITH THE STORM AND ITS
MAIN IMPACTS EXITING NORTHERN OKLAHOMA ON THURSDAY. WHILE ANY
FLOODING EVENT MAY BE LIFE THREATENING...THERE ARE INDICATIONS THAT
FLOODING WITH THIS TROPICAL SYSTEM COULD BE EXCEPTIONALLY SERIOUS
FROM PORTIONS OF WESTERN NORTH TEXAS NEAR AND EAST OF WICHITA
FALLS...AND ALSO FROM SOUTH-CENTRAL AND CENTRAL OKLAHOMA.

TO BE SURE YOU ARE PREPARED...HERE ARE SOME OF THE MOST SIGNIFICANT
IMPACTS THAT ARE POSSIBLE...

FLOODING RAIN:
WE EXPECT TO SEE BROAD RAINFALL TOTALS OF MORE THAN TWO INCHES BY
THURSDAY MORNING...AND SOME LOCATIONS WILL SEE FIVE INCHES OR MORE.
IF RAIN BECOMES CONCENTRATED JUST EAST OF THE STORM CENTER ON
WEDNESDAY EVENING...WHICH WE ARE CURRENTLY ANTICIPATING...A
SIGNIFICANT FLASH FLOOD EVENT COULD UNFOLD ACROSS PORTIONS OF
CENTRAL OKLAHOMA. IF YOU LIVE IN A FLOOD PRONE AREA...YOU SHOULD
CARRY THROUGH WITH YOUR FLOOD SAFETY PLANS AND BE PREPARED TO SEEK
HIGHER GROUND.

STRONG WINDS:
MANY LOCATIONS COULD SEE SEVERAL HOURS OF STRONG WIND TODAY AND
TONIGHT...WITH SUSTAINED WINDS OF 20 TO 30 MPH AND HIGHER GUSTS.
WINDS THIS STRONG WOULD CAUSE TRAVEL PROBLEMS...BLOW AROUND LOOSE
OBJECTS AND CAUSE MINOR DAMAGE TO TREES AND STRUCTURES.

TORNADOES:
AS THE REMNANT CIRCULATION OF HERMINE MOVES OVER WESTERN NORTH TEXAS
AND WESTERN OKLAHOMA...CONDITIONS WILL BECOME MORE FAVORABLE DURING
THE LATE MORNING...AFTERNOON...AND EARLY EVENING FOR SOME OF THE
EMBEDDED THUNDERSTORMS TO PRODUCE BRIEF...WEAK TORNADOES. WHILE THE
CHANCES FOR TORNADOES MAY BE SMALL...YOU SHOULD BE READY TO ACT
QUICKLY IF YOU HEAR A TORNADO WARNING OR FEEL THREATENED.

YOU ARE ENCOURAGED TO CHECK YOUR LOCAL WEATHER OFTEN TO BE SURE YOU
ARE AWARE OF ANY FORECAST CHANGES AND KNOW HOW TO STAY SAFE.
