AT 835AM...NATIONAL WEATHER SERVICE RADAR CONTINUED TO SHOW MODERATE TO
HEAVY RAINS MOVING OVER NORTHEAST LE FLORE COUNTY AND NORTHERN SEBASTIAN
COUNTY ARKANSAS. RADAR ESTIMATES AND SURFACE OBSERVATIONS INDICATE THAT
FROM 1 TO 2 INCHES OF RAIN HAS ALREADY FALLEN IN THIS AREA DURING THE

THERE WILL ALSO CONTINUE TO BE STREET FLOODING PROBLEMS IN AND AROUND
THE FORT SMITH AREA. THE POTEAU RIVER THAT RUNS THROUGH THE AREA WILL

PERIODS OF HEAVY RAIN.
 
MOST FLASH FLOOD DEATHS OCCUR IN AUTOMOBILES.  DO NOT DRIVE YOUR
VEHICLE INTO AREAS WHERE THE WATER COVERS THE ROADWAY.  THE WATER
MAY BE TOO DEEP TO ALLOW YOUR CAR TO CROSS SAFELY.  IF YOUR
