GREENVILLE, Calif.  — A 3-week-old wildfire engulfed a tiny Northern California mountain town, leveling most of its historic downtown and leaving blocks of homes in ashes as crews braced for another explosive run of flames Thursday amid dangerous weather.

The Dixie Fire, swollen by bone-dry vegetation and 40 mph (64 kph) gusts, raged through the northern Sierra Nevada community of Greenville on Wednesday. A gas station, church, hotel, museum and bar were among the fixtures gutted in the town dating back to California’s gold rush era where some wooden buildings were more than 100 years old.
