...INCREASED RISK OF ICE JAM FLOODING AS AIR SUB ZERO TEMPERATURES
MODERATE...
WHERE: SALMON RIVER 8 TO 13 MILES NORTH OF SALMON
WHEN: DURING THE SECOND HALF OF JANUARY, PARTICULARLY ONCE AIR
TEMPERATURES WARM NEAR FREEZING
WHAT: RECENT SUB ZERO TEMPERATURES HAVE ALLOWED RIVER ICE TO DEVELOP
WITHIN THE SALMON RIVER JUST NORTH OF SALMON, IDAHO. TRAINED RIVER
SPOTTERS HAVE NOTED TWO DISTINCT AREAS OF ICE BUILD-UP: NEAR 8 MILES
NORTH OF SALMON, AND NEAR 12 MILES NORTH OF SALMON. THE CONTINUATION
OF SUB ZERO TEMPERATURES AND THE EVENTUAL WARM-UP OVER THE NEXT
COUPLE OF WEEKS WILL ALLOW RIVER ICE TO MOVE AROUND AND MAY QUICKLY
JAM UP WATER FLOW, RESULTING IN LOWLAND FLOODING.
MORE INFORMATION WILL BE PROVIDED AS RIVER ICE CONTINUES TO
PROLIFERATE AND TEMPERATURES BEGIN TO WARM.
