HYDROLOGIC STATEMENT
NATIONAL WEATHER SERVICE MISSOULA MT
213 PM MST SUN DEC 21 2008
...THE NATIONAL WEATHER SERVICE IN MISSOULA CONTINUES A RIVER
STATEMENT FOR ICE FORMATION IN SMALL STREAMS AND RIVERS IN WESTERN
MONTANA AND NORTH CENTRAL IDAHO...
COLD TEMPERATURES WILL CONTINUE ACROSS WESTERN MONTANA AND
NORTH CENTRAL IDAHO.  THIS WILL LEAD TO MORE ICE BUILD UP IN
AREA SMALL STREAMS AND RIVERS.  FREEZE-UP ICE JAMS COULD RESTRICT THE
FLOW OF WATER IN SOME LOCATIONS. IF FREEZE-UP ICE JAMS GET LARGE
ENOUGH THEY WILL BEGIN TO BACK UP WATER INTO LOW LYING AREAS NEXT TO
THE RIVER AND CAUSE LOW LAND FLOODING.
IN MONTANA...COUNTY OFFICIALS HAVE REPORTED WARM SPRINGS CREEK IN
DEER LODGE COUNTY IS CAUSING SOME MINOR FLOODING IN THE
WASHOE PARK AND DEER PARK AREAS. THERE ARE ALSO REPORTS OF ICE ON THE
BITTERROOT RIVER DIVERTING WATER INTO LOW LYING FIELDS. STAY TUNED
FOR FURTHER UPDATES.
IN IDAHO...A NATIONAL WEATHER SERVICE TRAINED WEATHER SPOTTER REPORTS
NUMEROUS ICE JAMS FORMING IN THE SALMON RIVER. THE DEADWATER AND
NORTH FORK AREA HAS ICE JAMS BUILDING...ICE JAMS ARE ALSO FORMING
NEAR THE 4TH OF JULY CREEK AREA AND ARE BACKING WATER INTO FIELDS IN
THAT AREA. THE ICE JAM NEAR 4TH OF JULY CREEK IS ABOUT 12 MILES
NORTH OF THE TOWN OF SALMON. THESE ICE JAMS ON THE SALMON RIVER WILL
CONTINUE TO GROW INTO NEXT WEEK AS THE COLD AIR MASS REMAINS IN
PLACE. NO MAJOR FLOODING IS EXPECTED AT THIS TIME...ONLY MINOR LOW-
LAND FLOODING TO AREAS ADJACENT TO THE RIVER IS EXPECTED.
STAY TUNED TO DEVELOPMENTS BY LISTENING TO NOAA WEATHER RADIO OR YOUR
LOCAL TV OR RADIO STATIONS. INFORMATION CAN ALSO BE OBTAINED FROM OUR
