Flames ripped through brush and woodland on hills above the Californian city of Santa Barbara early on Tuesday.
According to Reuters, authorities have issued an evacuation for residents in northern areas of the city.
The fire broke out in Los Padres National Forest Monday afternoon and spread to cover 3,100 acres by the evening.
The blaze dubbed the “cave fire”, started near East Camino Cielo and Painted Cave Road in the forest.
Firefighters from neighboring areas are in Santa Barbara attempting to help local firefighters with the fast-moving blaze.
According to officials, the fires are stoked by high winds and are not contained.
The office of Governor Gavin Newsom is said to be closely monitoring the blaze.
