FLOOD WARNING
Warning Issue Date: 112 PM MST FRI JAN 01 2010
THE GALLATIN RIVER REMAINED OVER IT BANKS DUE
TO A MAJOR ICE JAM NEAR BIG SKY...INCLUDING AREAS ALONG HIGHWAY
191 AT RAINBOW RANCH ROAD. LITTLE CHANGE HAS OCCURRED IN
THE OVERALL LEVEL OF FLOODING AND ICE BUILDUP ALONG THE RIVER OVER
THE LAST 24 HOURS.
* IMPACTS...WHEN THE ICE JAM BREAKS...THERE IS THE POTENTIAL FOR
A SIGNIFICANT AMOUNT OF WATER TO RUSH DOWN THE GALLATIN
RIVER QUICKLY...CAUSING MORE FLOODING PROBLEMS
DOWNSTREAM. ADDITIONALLY...THERE IS THE POTENTIAL THAT DAMAGE
COULD OCCUR ALONG THE SHORELINE AND TO BRIDGES CROSSING THE
GALLATIN RIVER...FROM ICE AND OTHER DEBRIS WASHING DOWN THE RIVER.
ANYONE WHO LIVES ALONG THE GALLATIN RIVER FROM THREE FORKS TO BIG
SKY...SHOULD PREPARED TO MOVE QUICKLY SHOULD FLOODING OCCUR.
ANYONE WHO PLANS RECREATION ACTIVITY ON THE GALLATIN RIVER SHOULD BE
PREPARED FOR POSSIBLE ICE OR DEBRIS FLOW...WHEN THE ICE JAM BREAKS.
A FLOOD WARNING MEANS THAT FLOODING IS IMMINENT OR HAS BEEN REPORTED.
ALL INTERESTED PARTIES SHOULD TAKE NECESSARY PRECAUTIONS IMMEDIATELY.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
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.
FLOOD WATERS ARE MOVING DOWN THE GALLATIN RIVER FROM BIG SKY TO
THREE FORKS. THE FLOOD WARNING WILL REMAIN IN EFFECT UNTIL THE ICE
JAM BREAKS.
