There is a new grassroots organization of homeowners in the North Bay of CA (Sonoma, Napa, and Lake Counties) that have tech backgrounds that have started a non-profit and developed an app & website to provide the public with immediate information/intel on fires in these three counties.
I came across it last night during the flurry of 10 new starts in our County and was extremely impressed. I can see this catching on quickly to other counties. There is no charge, fees, advertising associated with the app, it is strictly public emergency information.

Disclaimer I am not affiliated nor do I know anyone involved with this project. I just happened upon it last night and thought it would be useful to others.
