...A FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 445 PM MDT FOR
NORTHWESTERN BONNEVILLE...EXTREME EAST CENTRAL BUTTE...CENTRAL
BINGHAM AND SOUTHWESTERN JEFFERSON COUNTIES...

AT 336 PM MDT...LOCAL LAW ENFORCEMENT OFFICIALS REPORTED SEVERAL 
PARKING LOTS AND ROADS FLOODED IN THE CITY OF BLACKFOOT.  

LOCATIONS IN THE WARNING INCLUDE BUT ARE NOT LIMITED TO SOUTHEAST 
INL...BLACKFOOT AND ROSE.  

PRECAUTIONARY/PREPAREDNESS ACTIONS...

EXCESSIVE RUNOFF FROM HEAVY RAINFALL WILL CAUSE FLOODING OF SMALL
CREEKS AND STREAMS...URBAN AREAS...HIGHWAYS...STREETS AND UNDERPASSES
AS WELL AS OTHER DRAINAGE AREAS AND LOW LYING SPOTS.

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. MOVE TO HIGHER GROUND.

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.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
154 PM MDT WED AUG 6 2014

.DISCUSSION...VERY MOIST LOW PRESSURE SYSTEM REMAINS CENTERED
OVER THE TWIN FALLS AREA THIS AFTERNOON. A DEFORMATION ZONE
EXTENDS NORTHEAST OF THE LOW...BANKED UP AGAINST THE CENTRAL
MOUNTAINS. MODERATE TO HEAVY RAIN IS FALLING IN THIS ZONE WITH
RAINFALL AMOUNTS UP TO AN INCH. SOUTH OF THE DEFORMATION
ZONE...THUNDERSTORMS ARE DEVELOPING. AS WAS THE CASE
YESTERDAY...THESE STORMS ARE PACKING HEAVY RAIN WITH AMOUNTS OF 1
TO 2 INCHES LIKELY IN THUNDERSTORMS. THE LOW WILL MOVE SLOWLY EAST
TONIGHT AND BE OVER EASTERN IDAHO ON THURSDAY. TOMORROW LOOKS TO
BE VERY MUCH A REPEAT OF TODAY...EXCEPT THE LOW WILL BE SHIFTED
OVER THE SOUTHERN HIGHLANDS ON THURSDAY. IT WILL NOT EXIT THE
REGION UNTIL FRIDAY. THEREFORE A FLASH FLOOD WATCH IS IN EFFECT
FOR ALL OF SOUTHEAST IDAHO UNTIL THURSDAY NIGHT.

SLIGHTLY DRIER AIR WILL WORK INTO THE REGION BEHIND THE LOW FOR
FRIDAY AND BEYOND. HOWEVER THERE WILL STILL BE ISOLATED TO SCATTERED
THUNDERSTORMS AROUND...ESPECIALLY IN THE MOUNTAINS. THINK THE FLASH
FLOODING THREAT WILL BE OVER ON FRIDAY THOUGH.
