CNN's chief climate correspondent, Bill Weir, has visited stricken Lahaina, and had this to say:

It looks like a bomb went off in Lahaina town. All the iconic buildings are either flattened or just scorched skeletons of their former self. Flames came so fast, entire structures went up in a matter of minutes. Anything in the town center here is just completely devastated. The fire was so hot, it burned everything all the way to the ground. [It's] just lifeless, smoky, and sooty devastation where Lahaina town used to be.
