Saturday into Sunday Storm (Jan. 7/8):
Beginning late tonight, Friday, Jan. 6, a moderate-strength system is expected to start impacting Santa Rosa with a couple of rounds of rainfall from Saturday through Sunday morning, as this will be another period of strong and gusty winds, though not as strong as what we experienced earlier in the week. A brief break in the rain late Sunday afternoon is expected.
Monday into Tuesday Storm (Jan. 9/10):
The storm arriving late Sunday, Jan. 8, will be the stronger system with the potential for greater impacts Monday and Tuesday. This system is expected to produce significant amounts of rainfall. In addition, winds are expected to strengthen, and with our saturated soil, even moderate gusts (versus strong gusts) will be of concern as it is easier for trees to come down in these conditions. Downed trees can lead to power outages, threaten lives, and exacerbate flooding, as trees and branches can clog waterways. This storm will be monitored by the National Weather Service (NWS), Sonoma County and City officials.
Flood Watch Issued (Jan. 7 - 10):
NWS has issued a Flood Watch for the greater Bay Area, which includes the North Bay. The Flood Watch will go into effect tomorrow, Saturday, Jan. 7, at 4 a.m. and is expected to end on Tuesday, Jan. 10, by 4 p.m. The NWS could upgrade the Flood Watch to a Flood Warning based on the conditions, as up to seven inches of rain is possible locally through Tuesday.

What to Expect:
- Downed trees are especially concerning following the amount of rainfall we have had and given how saturated the soil is. Expect tree debris potentially blocking roads or damaging property.
- Power outages are likely. If you spot a downed power line or a tree down into a power line, please call 9-1-1 to report it.
- Mud or landslides are possible. If you witness the beginning of a slide or see a partial slide, please call 9-1-1 to report it.
- Flooding, especially in areas with poor drainage.
- Standing water in roadways is also likely. Turn around, don’t drown. Don’t drive through standing or moving water.
- High-intensity rain may cause debris flows in the Glass Fire burn scar area.
Safety Tips During a Storm:
- Avoid unnecessary travel. Purchase groceries and supplies in advance for fewer trips during the storm.
- If you must travel, allow more travel time and slow down to a speed safer for the conditions.
- Do not drive into flooded areas. If floodwater rises around your car, abandon the car, and move to higher ground if you can do so safely. You and the vehicle could be quickly swept away.
- Do not walk in moving water. Six inches of moving water can make you fall. If you must walk in water, walk where the water is not moving.
- Never drive over a downed power line.
- The use of candles during a power outage is discouraged. If you do use them, do not leave candles unattended.
