Estimated fire map for the Silverado. As always this is for discussion and it not meant as a tactical tool, it is for discussion and orientation and was created solely from remote sensing with no on site validation.

That’s about right for Fremont on a cold Santa Ana.

From radio traffic…fire in backyards west of portola parkway

That is the same section of homes that burned in the last 2 fires ORC has had in there. It always follow the exact same foot.

I have seen SCE weather stations and wonder how accurate they are. Their setup does not comply with NWS guidelines. I look for NWS approved sites or CDEC sites just for accuracy.

ABC7 Is saying new reports from officials is approx. 500 Acres revising from the earlier report of 2,000 acres.

Just saw this “new” start. Don’t see any aircraft overhead, not even an air attack. Grounded due to wind?
