In such firestorms, many buildings are doomed by embers, which may be lofted for hundreds of yards then fall like snowflakes. These burning bits of debris find ways to penetrate interiors, which are typically filled with furniture, rugs, paneling and other volatile materials.
“Embers will exploit any vulnerability in a home — and once they get inside and ignite, it is very unlikely to survive,” said Kelly Pohl, a researcher at Headwaters Economics.
