A wildfire in Lake Tahoe, Calif., that has destroyed at least 220 homes and forced about 1,000 people to flee their neighborhoods along the Lake’s southern edge as of Monday is anticipated to incur more than $25 million in insured losses, according to estimates by risk modeling company Air Worldwide Corp. The fire, which is believed to be caused by human activity, was approaching 2,500 acres and was 10 to 15 percent contained as of press time, Lt. Kevin House of the El Dorado County Sheriff’s Department told the Associated Press. No injuries have been reported.
