...A FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 330 PM MDT FOR

THUNDERSTORMS WITH VERY HEAVY RAIN ARE POSSIBLE LATER THIS 
AFTERNOON. ANY STORMS WILL SLOWLY MOVE NORTH AT 10 TO 15 MPH. IN 
ADDITION...ALREADY SATURATED GROUND FROM RECENT RAINS WILL MEAN THAT

THE THUNDERSTORM PRODUCING VERY HEAVY RAIN WILL AFFECT THE FOLLOWING 
LOCATIONS...QUEEN...STATE HIGHWAY 137 AND THE HORSE CANYON BURN SCAR 
AREA.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

EXCESSIVE RUNOFF FROM HEAVY RAINFALL WILL CAUSE FLOODING OF SMALL
CREEKS AND STREAMS...COUNTRY ROADS...AS WELL AS FARMLAND ALONG THE
BANKS OF CREEKS AND STREAMS.

BURN SCARS FROM RECENT FIRES HAVE INCREASED THE PROBABILITY FOR 
LOCALIZED HEAVY RUNOFF AND ROCKSLIDES. 

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.
