BULLETIN - EBS ACTIVATION REQUESTED
FLASH FLOOD WARNING
NATIONAL WEATHER SERVICE OKLAHOMA CITY OK
1250 AM CDT MON MAY 01 1995

THE NATIONAL WEATHER SERVICE IN OKLAHOMA CITY HAS ISSUED A
FLASH FLOOD WARNING EFFECTIVE UNTIL 315 AM CDT FOR PEOPLE IN
THE FOLLOWING COUNTIES

IN SOUTHEASTERN OKLAHOMA
     BRYAN...JOHNSTON AND MARSHALL

INCLUDING THE FOLLOWING LOCATIONS
     ALBANY...BROWN...CALERA...COBB...DURANT...EMET...FILLMORE
     ...KIERSEY...KINGSTON...LITTLE CITY...MADILL...MEAD...
     MILBURN...NIDA...OAKLAND...PLATTER...RAVIA...ROBERTA...
     RUSSETT...SILO...TISHOMINGO...TROY...UTICA AND WOODVILLE

AT 1250 AM CDT RADAR INDICATED THUNDERSTORMS PRODUCING TORRENTIAL
RAINFALL MOVING INTO MARSHALL...BYRAN AND JOHNSTON COUNTIES. THESE
STORMS WILL MOVE SOUTHEAST ACROSS THE AREA AND PRODUCE ONE TO TWO
INCHES OF RAIN. THIS RAIN WILL BE IN ADDITION TO THE AMOUNTS OF OVER TWO
INCHES THAT FELL EARLIER IN THE EVENING. FLASH FLOODING LIKELY WILL
RESULT.

BE ESPECIALLY CAUTIOUS AT NIGHT WHEN IT IS HARDER TO RECOGNIZE
THE DANGERS OF FLOODS AND FLASH FLOODS.  IF FLASH FLOODING IS
OBSERVED...ACT QUICKLY.  MOVE UP TO ESCAPE FLOOD WATERS.  DO
NOT STAY IN AREAS SUBJECT TO FLOODING WHEN WATER BEGINS RISING.
IT IS VERY DIFFUCULT AT NIGHT TO TELL HOW MUCH WATER IS ON
ROADS.  MOTORISTS SHOULD NOT DRIVE THROUGH WATER OF UNKNOWN
DEPTH.

DO NOT DRIVE YOUR VEHICLE INTO AREAS WHERE WATER COVERS THE
ROADWAY.  THE WATER DEPTH MAY BE TOO GREAT TO ALLOW YOUR CAR TO
CROSS SAFELY.  VEHICLES CAUGHT IN RISING WATER SHOULD BE
ABANDONED QUICKLY.  MOVE TO HIGHER GROUND.  REMEMBER...MOST
DEATHS IN FLASH FLOODING OCCUR IN AUTOMOBILES.  IT ONLY TAKES A
FOOT OR TWO OF FLOWING WATER TO WASH MOST CARS AWAY.
