Above is the 5 day total precipitation forecast for December 17-22.
Friday December 21 - Wednesday December 26
A series of weather systems will move across northern California during this six day period bring periods of rain and snow in the higher elevations. The heaviest precipitation is expected Saturday night through the day Sunday. The outlook is calling for the potential of 1 to 2 inches of rain during this period. Thus there is a potential for the mountain passes to be impacted by snow.
Snow level will be near 4,000 feet on Friday and Saturday and lower to near 3,500 feet on Sunday and remain near 3,500 feet through Wednesday.
Potential impacts with mid to late-December precipitation
Due to the saturated soil, all the main stem rivers will have rapid rises.The tributary creeks and small rivers will also have significant rises and flows.Rock and mudslides along highways and county roads in mountainous terrain.
Power outages are possible due to strong winds and blown down tree branches.
Potential for hazardous driving conditions due to snow accumulation on mountain passes and higher elevation roadways with the colder systems.
