A massive power outage has left approximately 5,000 residents without throughout central Marin. Police reports estimate that power is out in all of San Anselmo, Fairfax, Ross, San Rafael, parts of Larkspur and Corte Madera and parts of unincorporated Marin County.

Police in Novato and Mill Valley said they had not yet received any calls of outages, but San Anselmo police officers said outages have been reported as far away as Cotati and Monterey County.

PG&E representatives didn't have an estimate on when power would be restored and are currently attempting to determine the extent and cause of the outage. Power in some areas of San Rafael has already been restored.

Residents are advised to use extreme caution as many traffic lights have been affected, including along Sir Francis Drake Boulevard and around the Civic Center.
