AT 722 PM CDT...NWS METEOROLOGISTS CONTINUED TO DETECT MODERATE TO 
OCCASIONALLY HEAVY RAINS OVER PARTS OF THE AUSTIN METRO AREA. 
DOPPLER RADAR ESTIMATED RAINFALL RATES OVER BURNET AND WILLIAMSON 
COUNTIES ARE MAINLY AROUND 1/2 INCH PER HOUR OR LESS. THESE RAINFALL 
RATES WILL NOT LIKELY PRODUCE NEW FLOODING...BUT COULD PROLONG 
EXISTING FLOODING ACROSS BURNET AND WILLIAMSON COUNTIES.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

EXCESSIVE RUNOFF FROM HEAVY RAINFALL WILL CAUSE FLOODING OF SMALL
CREEKS AND STREAMS...URBAN AREAS...HIGHWAYS...STREETS AND UNDERPASSES
AS WELL AS OTHER DRAINAGE AREAS AND LOW LYING SPOTS.

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.
