Water levels around ice jams are notoriously unpredictable, and can change quickly with little or no warning. Anyone living or recreating near the river should pay close attention over the next few days and prepare for additional changes in water levels.

Heavy rain may fall on a deep primed snowpack leading to the melt increasing. Flows in rivers may increase quickly and reach critical levels. ...FLOOD WATCH IN EFFECT FROM WEDNESDAY EVENING THROUGH LATE THURSDAY NIGHT... * WHAT...A combination of melting snow and rain may result in flooding of area creeks and streams.
