Summary
Forecasters are predicting more rain today, and advise community members to be on the lookout for flooding and the impacts of high winds. New precipitation amounts between a half and three quarters of an inch possible, with widespread wind gusts 35-45 mph and isolated gusts 50+ mph along the coast. Excessive runoff may result in flooding of creeks, streams, and other low-lying and flood-prone locations. Creeks and streams may rise out of their banks. Flooding may occur in poor drainage and urban areas. Damaging winds may blow down trees and power lines. Widespread power outages are expected and roadways could be blocked by downed trees.

Please note that the safety of our citizens is the first priority of City work crews, and that replenishing the sand pile and bags may become a lower priority during a storm event. If you have questions or comments please call your local Department of Public Works.
During the storm
- Avoid unnecessary travel. Strong winds and wet roads make travel risky, and possible flooding may prevent you from returning home. Staying home is the safest option until the storm passes. If its an emergency, allow emergency responders to come to you.
- Use extra caution when driving. If you MUST leave your home, drive carefully: slow down, keep both hands on steering wheel, turn on head lights, allow extra space between vehicles, and watch for downed tree branches, trees, and powerlines. Allow extra time in case of detours away from flooded roadways.
- Do not walk or drive around barricades or through standing water. Turn around, do not drown. If it’s an emergency, allow emergency responders to come to you.
- Stay away from downed power lines. Always assume a fallen power line is live and do not touch it with your hand or other object. Call 9-1-1 immediately to report the fallen line.
- Mariners / Houseboats should remain in port. Strong winds and cause hazardous seas which could capsize or damage vessels.
- Monitor Emergency.MarinCounty.org for the most up-to-date weather and emergency information.

- If traffic signals are out or flashing red, come to a full stop at every intersection, and proceed as you would at a four-way stop.
Mudslides
