The vegetation fire burning in a rural area between Arroyo Grande and Nipomo held at 244 acres Thursday, while containment grew to 75 percent, Cal Fire said.
The fire started just before 2 p.m. Wednesday in the 4900 block of Huasna Townsite Road, according to Cal Fire.
Cal Fire spokesman Chris Elms said Thursday morning the agency had “a lot of ground and air resources working very hard to complete containment while the weather is in our favor.”
By Thursday night, forward progress had been stopped and firefighters continued to build and strengthen containment lines and put out hot spots, according to Cal Fire.
Steep terrain and heavy vegetation in the area made access and containment line construction difficult, Cal Fire said.
Elms said he anticipates crews working on scene through Friday.
