Thomas Fire is 89 percent contained

The massive Thomas Fire that burned 281,620 acres in Ventura and Santa Barbara counties is 89 percent contained, as of Wednesday morning, according to Cal Fire.

Now the largest wildfire in California history, the Thomas Fire destroyed 1,063 structures and damaged 280. Approximately 775 single-family homes were destroyed.

On Dec. 4, the Thomas Fire ignited north of Santa Paula near highways 150 and 126. Santa Ana winds fueled the blaze, pushing it into Santa Barbara County and leading to the destruction of multiple expensive homes in Montecito.

Currently, very little active heat remains, and fire officials do not expect any more forward progress of the blaze. However, the area west of Cherry Creek Road still contains large sections of fuel that officials believe will burn when certain weather conditions return.

Hotspots also remain in the Bear Heaven area of Ventura County. Likewise, about 30 oil seep fires have ignited in the Upper Ojai area and continue to burn. Authorities have ordered a foam product that may help extinguish the oil seep fires.

Officials have called off all mandatory evacuations. Some sections of the Los Padres National Forest remain closed, though.

Air quality is now good in most of Santa Barbara County and moderate in most of Ventura County, according to Cal Fire. Officials are encouraging visitors to come to Santa Barbara, Ventura and surrounding areas during the upcoming New Year’s holiday.

Investigators have yet to determine the cause of the Thomas Fire.
