Wet, windy weather to return tonight, stay until next week

From the National Weather Service:
Dry weather continues across Northern California through this afternoon. River and stream levels are still elevated and will be slow to recede. The next weather system is set to arrive late tonight into Thursday, with lighter showers Friday through the weekend. The precipitation forecast for these storms do not appear to be as high as last week's storms. Those storms last week have left the region highly vulnerable, so amplified impacts will be possible with additional rainfall. Potential is increasing for a stronger, wetter storm with stronger winds early next week. A continued wet pattern is expected through next week.

Impacts
Flooding issues linger, water levels will be slow to recede
Renewed flooding concerns by late this week
Hazardous mountain travel this weekend
Gusty winds may bring downed trees and cause power outages

Forecast Confidence
High through the weekend
Medium for stronger, wetter storm Monday-Tuesday

Timing and Strength
Dry weather today through this afternoon
Most rivers have crested at this time, but flood waters will be slow to recede
Use this period to assess damages, clean-up ahead of next storms
