Reminder to residents: Be prepared for storm hazards

Continued risk of flooding and mud, debris flows in 2020 wildfire burn scar areas

Santa Rosa, CA  –  October 22, 2021  –  The National Weather Service announced today a Flash Flood Watch for the North Bay, including Sonoma County, ahead of an atmospheric river forecast to arrive on Sunday, Oct. 24. This weather system is expected to bring four to six inches of rain to parts of the county, with some wetter areas and higher elevations seeing as much as nine inches of rain.

Residents living in and around wildfire burn scar areas are at higher risk of flash floods, rock falls and mud and debris flows and are reminded to be prepared for these hazards associated with storms. To help residents assess potential hazards and be prepared, the County of Sonoma has created Rain Ready Maps for the Glass Fireand for the LNU Lightning Complex (or Walbridge and Meyers fires).

Property owners are advised to use erosion control techniques, such as installing wattles and rock bags, and clearing fire-related debris from creeks and drainages to reduce flooding. For additional erosion prevention information, visit srcity.org/RainReady. Rain preparedness information can also be found online for the unincorporated areas of Sonoma County in the LNU Lightning Complex and Glass Firewebpages on socoemergency.org.

It is equally important to remain alert to possible threats and be prepared to evacuate if you receive an emergency alert or warning for your designated evacuation zone. If anyone feels in danger, they should never wait for an evacuation notice to leave their home. Don’t hesitate to evacuate. Know your zone – look up your evacuation zone online at socoemergency.org/get-ready/evacuation-map/.

Residents should be advised of the following safety information:

Be prepared to go

Pack emergency supply bags and identify what you would want to save in an emergency. Consider the 6 P’s: People and pets, important papers, prescriptions, pictures, personal computers and plastic/paper money.

Create an evacuation plan and include two possible evacuation routes.

Maintain awareness of potential hazards

Flash flooding: Normally, rainfall is absorbed by vegetation and soils, reducing runoff. However, wildfires remove vegetation and may leave soil unable to absorb water, creating potential flash flood conditions. Flood risk remains significantly higher until vegetation is restored — up to five years after a wildfire.

Mud and debris flows: Debris and ash, along with other sediments, can be picked up in flood waters and form mud and debris flows.

Report flooding or mud and debris flows by calling 9-1-1.
