Everyone that lives in California (and thus the evac zone) would know to check CalFire (ie, www.fire.ca.gov) for any wildfire maps before looking at any other source because it would be the most accurate and most up to date.

Wildfires are such a common thing (car off the side of the state/interstate hwy, brush fire set off by a homeless encampment in public land, massive forest fire, etc - all would be on CalFire; for a local building fire you would have to check local authorities). We all know if we see smoke to check CalFire to get the details and if it's heading our way. It even shows things happening in Mexico and nearby states in case it's heading towards us.

Could be dishonest opportunistic propaganda from this guy

This, or someone completely unfamiliar with California
