Californian fire ecologist Chad Hanson has given me some of the main developments since I last spoke to him yesterday. He tells me the most striking aspect right now for him is seeing the scale of destruction.
“What we have seen are entire neighbourhoods which have been wiped out,” he says. “Homes gone, businesses gone.
Hanson says the “devastation is kind of hard to get your mind around. Five people have been killed – it could have been hundreds.”
Since first responders realised that conditions would prevent them from containing the fires, they focussed their efforts on evacuating residents instead.
“They did an extraordinary job.”
Hanson says there is a prediction of another Santa Ana wind event next week.
“There is no rain predicted between now and then,” he adds. “It’ll be even drier and if we have another Santa Ana event” then any remaining or new fires that could spark up.
