I am S100 certified for forest fire fighting. I took the course when I lived in a small city where a forest fire was getting very close to the city. The fires generate their own weather and that sometimes means the fire goes in unpredictable directions. The super heat comes in 3 forms. Radiant, convection and conduction but the convection and radiant heat are the worst of them in this situation. I heard from a experienced wildland forest fire fighter that at a distance of 1500 feet (457m) they could not stand the heat of the candling trees as the fire's superheated air and radiant heat caused trees in the fire path to spontaneously ignite without a flame applied. The description included vivid terms that defined a hurricane like/roaring tornado thing that carried burning branches and even entire burning trees around in the air currents. Weather reports are critical but eyes on the fire are the best method of predicting the airflows and such. The fireproof tents that fighters are equipped with in Canada are called, "Shake and bake tents." Canada does not issue these tents because by this time the fighters are supposed to be long gone from the fire's path of destruction and because the tents do not protect enough for a viable shelter as can be seen in some USA fire fighters' deaths when they took shelter in the shake and bake tents. So get out fast if a forest fire is coming and no sightseeing because you may well be in something that is inescapable or worse if that is even possible.Take care - those wild fires can move fast and unpredictably. Make sure you have an escape route planned. A boat and the ocean are probably particularly effective
(I've been listening to a "True Survival" podcast series - at least three episodes of which involved people trapped by wildfires. In all cases all the forecasts said it wouldn't get near them.)
