January 2, 2017 – Moisture from the Pacific will interact with a cold upper low just off the Pacific Northwest coast and bring periods of heavy rainfall to interior northern California. Heavy rainfall and increasing snow levels will result in runoff of rain and melting snow into small streams, creeks and main stem rivers.
The National Weather Service in Sacramento has issued a flood watch for the west slope northern Sierra Nevada and adjacent foothills generally below 5000 feet.
Heavy rain is expected from Tuesday evening into Thursday morning.
Mountains and foothills: A total 4 to 7 inches of rain is expected through early Thursday with the heaviest totals over the western slopes of the Sierra Nevada Tuesday evening through Wednesday night.
