Earlier we received reports of a quarter acre vegetation fire on the west side of Panoramic Highway and Muir Woods Road. The fire was slow moving and there was no immediate threat to structures. Marin County Fire, Mill Valley Fire and other agencies responded and reported that the forward progress has been stopped. Aircraft has been canceled and the fire is under investigation. 32 personnel are on scene to "mop up" - which means extinguishing or removing burning material.
There is a power outage impacting parts of Mill Valley. PG&E is investigating the cause. Go here for more info: https://m.pge.com/#outages
