FLOOD STATEMENT
NATIONAL WEATHER SERVICE POCATELLO ID
1128 AM MDT THU APR 26 2012

...THE FLOOD WARNING CONTINUES FOR THE FOLLOWING RIVERS IN IDAHO...
 
  HENRY'S FORK AROUND ST. ANTHONY AFFECTING FREMONT AND MADISON COUNTIES
 
  HENRY'S FORK NEAR REXBURG AFFECTING MADISON COUNTY
 
.WIDESPREAD RAIN AND ISOLATED THUNDERSTORMS WILL PRODUCE PERIODS OF
HEAVY RAIN TODAY THROUGH FRIDAY EVENING.  SNOWMELT FROM THE RECENT
WARM TEMPERATURES COMBINED WITH THE RAINFALL WILL CAUSE THE HENRY'S
FORK TO GO INTO MINOR FLOODING FROM AROUND THE ST. ANTHONY AREA
DOWNSTREAM TO THE CONFLUENCE OF THE SNAKE RIVER.


PRECAUTIONARY/PREPAREDNESS ACTIONS...

 DEBRIS IN AND NEAR THE RIVER MAY START TO MOVE DOWNSTREAM AND
CAUSE ADDITIONAL CONCERNS.  DUE TO THE SNOWMELT...THE WATER
TEMPERATURES ARE EXTREMELY COLD AND POSE EVEN MORE DANGER TO
THOSE WHO MAY FALL IN.  HYPOTHERMIA IS LIKELY IF YOU GET WET.

 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.

 IF YOU LIVE NEAR THE RIVER YOU SHOULD BE AWARE OF THE
EXPECTED HIGH WATER AND TAKE ACTION TO PROTECT PROPERTY NOW.
