On evac planning... it’s worth packing a cooler full of ice, & frozen water bottles, in case the car overheats and you have to pull the hot air from the engine into the passenger compartment to keep moving. Hot winds outside, Heater blowing on full blast = heat exhaustion & delirium very quickly. The last 4 forest fires I was in 3 of the vehicles overheated after less than an hour. All 3 newer cars, computers couldn’t process the info coming at them, and crapped out. Easy peasy, lemon squeezy... soak your head & shirt & seat, stick ice in your bra and pockets , and repeat when you dry out. The worst was every 10 minutes or so, 60C melts and evaporates fast. Some lasted half an hour to an hour, more in the 50C range. I’d have been a hot mess without the cooler.
Stay safe out there.
