After a recent storm produced destructive winds over 100 mph, another round of strong winds on Sunday may cause additional damage and power outages.

- Additional rainfall totals of 3 to 5 inches (locally higher) are expected in coastal ranges and foothills of northern California and southwest Oregon through this weekend.
- Additional heavy snowfall is expected from the central Sierra Nevada northward into Cascades. Snowfall totals will be measured in feet in the highest elevations of the Sierra.
- Depending on how persistent the rain is, flooding could become widespread. Significant rises on rivers and streams are also likely. The National Weather Service has issued flood watches for parts of northern California, including Sacramento, the Bay Area and Redding, as well as parts of western Oregon.
- Mudslides and rockslides are probable, and may become numerous, particularly near burn areas.
- Strong winds at times could down trees in some areas, particularly where soils are recently saturated or where trees have been weakened by the multi-year drought. High wind watches and warnings have been posted for portions of the Pacific Northwest, for Sunday, where locally damaging winds will be possible. Wind advisories have been issued for portions of California through early Saturday, including the San Francisco and Los Angeles metro areas.
- Our forecast rain and snow map through Monday illustrates the expectation of several inches of rain in the lower elevations and feet of snow in the mountains. The heaviest amounts are focused from northern and central California into the Northwest.
