INTENSE RAINFALL OF OVER AN INCH ON 20 TO 40 MINUTES IS EXPECTED 
FROM THESE STORMS. DUE TO THE SATURATED CONDITIONS ALREADY ACROSS 
THE WARNED ARE FROM THE RAINFALL OF THE PAST FEW DAYS...THE RUNOFF 
FROM THESE NEW RAINS WILL CAUSE RAPID RISES ON AREA STREAMS AND 
CREEKS...AND THE INTENSE RAINFALL RATES WILL LIKELY LEAD TO STREET 
FLOODING IN ANY URBANIZED AREAS.

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.
