Raked by ferocious Santa Ana winds, explosive wildfires northwest of Los Angeles and in the city's foothills burned a psychiatric hospital and scores of homes Tuesday and forced the evacuation of tens of thousands of people.
One of the blazes broke out Monday in Ventura County and grew wildly to more than 70 square miles (180 square kilometers) in a matter of hours, county Fire Chief Mark Lorenzen said. It was fanned by winds clocked at well over 60 mph (96 kph) that grounded firefighting helicopters and planes.
A smaller fire erupted on the northern edge of Los Angeles, threatening the Sylmar and Lakeview Terrace neighborhoods, where residents scrambled to get out as heavy smoke billowed over the city, creating a health hazard for millions of people.
Just weeks ago, wildfires that broke out in Northern California and its famous wine country killed 44 people and destroyed 8,900 homes and other buildings.
Fires aren't uncommon in Southern California this time of year before the winter rains set in, when the vegetation is tinder dry and winds blast the region.
The early official count was that at least 150 structures burned in the Ventura County fire, but it was sure to go higher. Mansions and modest homes alike were in flames. The Vista del Mar Hospital, which treats patients with mental problems or substance abuse, including veterans with post-traumatic stress syndrome, smoldered after burning overnight.
Aerial footage showed dozens of homes in one neighborhood burned to the ground and a large subdivision in jeopardy as the flames spit out embers that could spark new blazes.
More than 27,000 people were evacuated and one firefighter suffered bumps and bruises in a vehicle accident in Ventura County. Authorities initially reported one death, but then retracted that, saying a dead dog but no person was found in an overturned car.
The fire erupted near Santa Paula, a city of some 30,000 people about 60 miles (97 kilometers) northwest of Los Angeles known for its citrus and avocado orchards and farm fields along the Santa Clara River.
