HYDROLOGIC STATEMENT
NATIONAL WEATHER SERVICE GREAT FALLS MT
1146 AM MST SUN JAN 5 2014
...ISOLATED ICE JAMS MAY IMPACT RIVERS ACROSS CENTRAL MONTANA THROUGH
MID-WEEK...
RAPIDLY CHANGING TEMPERATURES FROM ABOVE FREEZING TO BELOW ZERO HAVE
CAUSED ICE JAMS TO DEVELOP ALONG NUMEROUS RIVERS...CREEKS AND SMALL
STREAMS THIS WEEKEND. ADDITIONAL RAPID CHANGES IN TEMPERATURE ARE
ANTICIPATED IN THE COMING DAYS AS THE ARCTIC AIRMASS OVER THE REGION
MOVES EAST AND WARMING CHINOOK WINDS DEVELOP ACROSS CENTRAL MONTANA. 
ICE JAMS ARE UNPREDICTABLE...AND THEY CAN DEVELOP AND BREAK UP
RAPIDLY. ANYONE WHO LIVES...WORKS OR RECREATES ALONG WATERWAYS
SHOULD STAY ALERT FOR RAPID FLUCTUATIONS IN WATER LEVELS OVER THE
NEXT FEW DAYS.
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 IF YOU SEE RAPID CHANGES IN WATER
LEVELS.
TO REPORT FLOODING...HAVE THE NEAREST LAW ENFORCEMENT AGENCY RELAY
YOUR REPORT TO THE NATIONAL WEATHER SERVICE FORECAST OFFICE.
