One of the main differences I was thinking about compared to fires on the mainland is the size of the fire crew on the island is the size you have to work with. Getting additional manpower and gear isn't as easy as driving there.
Absolutely. Another factor is that there aren’t numerous highly organized, dedicated wildfire suppression crews like hotshot crews, smokejumpers, large wildfire engines (like Forest Service, BLM, CalFire, etc), or air tankers and retardant bases. But most important, when 60 mph winds blow on dry vegetation, none of that stuff I mentioned will be effective in preventing the spread, they can only be used on evacuation and point protection. Aircraft would be grounded.
I don’t think that Hawaii gets this combination of dry vegetation and 60 mph winds very often. For sure sugar cane fields wouldn’t have been lit during those sort of conditions. Hawaii has a wildfire history but not catastrophic as this, largely because of unusual conditions. I think that’s the case anyway.
Another thing I thought of is when I’ve been to west Maui, the (few) highways have been routinely jammed in the morning and evening. I would think that has been a factor, as well as the rural nature of many areas and roads.
