Firefighters battling an arson blaze that is racing toward thousands of homes in Foothill Ranch were forced this afternoon to abandon a mountain peak where they hoped to make a last-ditch stand.
Forty-foot-tall flames and smoldering embers were bearing down on the Lake Forest neighborhood and residents were evacuating after fire officials’ pleas for water-dropping helicopters went unheeded.
The Santiago Fire was deliberately set in three areas next to the 241 toll road about 6 p.m. Sunday, and it exploded quickly, fueled by dense vegetation and fierce Santa Ana winds, fire investigators said. The blaze has scorched more than 15,000 acres near Santiago Canyon and is now threatening Portola Hills
