We still don鈥檛 know the cause, but by night鈥檚 end, flames from 听were sweeping down from the hills of wine country and into Bay Area suburbs鈥擧ealdsburg, Redwood Valley, and Santa Rosa.听
For twelve long hours, the Diablo winds howled. Flames leaped from brush to home, unbeknownst to sleeping families, utterly impossible for firefighters to control. The embers raining down were unquantifiable. 鈥淵ou don鈥檛 count the number of raindrops in a downpour,鈥 says Mark Finney, a research forester with the National Forest Service. Every planter box, pine needle, garden, or roof touched by the blizzard of flames ignited. More than and overnight. Thousands of residents and visitors evacuated. At least . Six hundred and seventy others remain missing. With the winds forecast to return tonight, and increase again in severity this weekend, the disaster rages on.
Just how bad are the Napa fires? 鈥淭hese things aren鈥檛 unprecedented at all,鈥 says Finney. True. But for now, these fires have few modern rivals.
