WASHINGTON...SOUTHERN GRIMES...NORTHWESTERN HARRIS...WESTERN
MONTGOMERY...EXTREME NORTHEASTERN COLORADO...WALLER AND AUSTIN
COUNTIES...

AT 1008 AM CDT...LIGHT TO MODERATE RAIN IS OCCURRING...WITH A FEW 
EMBEDDED HEAVY DOWNPOURS. STREET FLOODING IS BEING REPORTED IN 
WALLER AND BRENHAM. AUSTIN COUNTY SHERIFF REPORTS SEVERAL FLOODED 
ROADS ACROSS THE NORTHERN PART OF THE COUNTY. ALTHOUGH RAINFALL 
RATES HAVE SUBSIDED FROM EARLIER LEVELS THE GROUND IS SATURATES. 
THIS ADDITIONAL RAIN EVEN THOUGH MOSTLY LIGHT TO MODERATE WILL STILL 
RUNOFF AND CONTRIBUTE TO ONGOING FLOODING. PORTIONS OF THIS WARNING 
MAY NEED TO BE EXTENDED. DO NOT DRIVE INTO FLOODED ROADS!

SOME LOCATIONS THAT WILL EXPERIENCE FLOODING INCLUDE...
BRENHAM...KATY...JERSEY VILLAGE...TOMBALL...HEMPSTEAD...SEALY...
PRAIRIE VIEW...BELLVILLE...BROOKSHIRE...PINEHURST...WALLER...
MAGNOLIA...SAN FELIPE...PINE ISLAND...MONTGOMERY...PATTISON...
STAGECOACH AND TODD MISSION.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

DO NOT DRIVE YOUR VEHICLE INTO AREAS WHERE THE WATER COVERS THE
ROADWAY. THE WATER DEPTH MAY BE TOO GREAT TO ALLOW YOUR CAR TO
CROSS SAFELY.  MOVE TO HIGHER GROUND.

MOST FLOOD DEATHS OCCUR IN AUTOMOBILES. NEVER DRIVE YOUR VEHICLE
INTO AREAS WHERE THE WATER COVERS THE ROADWAY. FLOOD WATERS ARE
USUALLY DEEPER THAN THEY APPEAR. JUST ONE FOOT OF FLOWING WATER IS
POWERFUL ENOUGH TO SWEEP VEHICLES OFF THE ROAD. WHEN ENCOUNTERING
FLOODED ROADS MAKE THE SMART CHOICE...TURN AROUND...DONT DROWN.
