The Alisal Fire charred over 24 square miles (62 km2) of dense chaparral in Santa Ynez Mountains, west of Santa Barbara. Wednesday night, containment was 5%
Although the area along the Pacific coast is not heavily populated, officials from fire departments said that the blaze was a danger to more than 100 homes and ranches.
Rancho del Cielo was being protected by fire crews. It was previously owned by Ronald Reagan and Nancy Reagan. The ranch covering 688 acres (278 hectares) where Reagan hosted world leaders is high up in the mountains, above the flames that feed on dense chaparral grasses.
According to staff reports, the fire was approximately a half-mile away (0.8 km) Wednesday evening. However, that section was not as active, according Jessica Jensen. She is vice president and chief executive officer of the Young America's Foundation which operates the ranch.
"We are grateful that there has not been any fire activity on the Reagan Ranch property. Jensen stated that the Ranch is in a stable position and sent an email to The Associated Press.
According to conservative youth organizations, the area had not burned since 1955.
The foundation stated that fire engines were present on ranch property and that fire retardant would be applied around the structures. It also noted that the ranch has two lakes, and helicopters have filled up with water.
Crews also protected Exxon Mobil Corp.'s gas processing plant in a canyon that was surrounded by flames.
Andrew Madsen, spokesperson for the U.S. Forest Service, stated that the highway might remain closed until the weekend.
More than a dozen helicopters and air tankers dropped water to help firefighters working in rugged terrain. However, changing winds can cause aircraft to be grounded, according to Jim Harris, Los Padres National Forestfire Chief.
Harris stated that "as the winds shift it's most dangerous and crucial time of the fire because the fire will change direction towards us."
According to the National Weather Service, there will be another round of notorious Sundowner winds in south Santa Barbara County Wednesday night. Other parts of California are also expected to face increased fire danger.
Red flag warnings are expected to be in effect for the interior of Northern California due to gusts and low humidity on Thursday. A fire weather watch was also issued Friday by forecasters in Southern California due to the possible development of Santa Ana winds.
Pacific Gas & Electric stated that it will likely need to turn off electricity in 13 Northern California counties Thursday in order to prevent wildfires being started by wind damage to powerlines. About 25,000 customers had lost power due to Monday's winds. The utility has just restored power.
According to the California Department of Forestry and Fire Protection, wildfires in California have destroyed nearly 3,900 homes and businesses, and scorched close to 3,900 square miles (10.101 kilometers) of land.
Wildfires are becoming more difficult to combat because of a historic drought in the American West, which is linked to climate change. It has already killed millions of trees in California. Scientists believe that climate change has made West more dry and warmer over the past 30 years. This will make wildfires more destructive and more extreme in the West.
