Sonoma County residents will receive test emergency warning alerts on their landline and cell phones in the evening of Sep. 11.
Sonoma County Emergency Services will use the SoCo Alert system to send the test alert around 6 p.m. No action by residents is required. Residents may sign up for the alerts at www.socoalert.com.
On Sep. 12, federal Wireless Emergency Alerts will be tested between 10 a.m. and noon in Healdsburg, Guerneville, Penngrove, Roseland, and the Glen Ellen-Kenwood areas.
The test alerts on Sep. 12 will be sent to cell phones unless the cell service has been turned off or if there is not a compatible smartphone available.
Sonoma County and Santa Rosa officials will be asking residents for feedback on the reach of these alerts, and a link to provide feedback will be provided at the time of the alert.
County officials also will test the Emergency Alert System over local media on Sep. 12. Local radio and television stations will send a test alert around noon.
Residents may call (707) 565-3856 with any questions about the alerts during the test.
