One of California’s largest wildfires this year has slowed dramatically, with firefighters saying that the Oak Fire west of Yosemite National Park is at least 64% contained.

But one fact announced by Cal Fire is perhaps more reflective of the progress in battling the blaze: The fire did not grow Saturday night after spreading by just four acres the previous day. And containment has increased by 12 percentage points from Saturday morning to Sunday morning.

As of 7:45 a.m. Sunday, the fire had burned 19,244 acres since it started July 22 along Highway 140 and Carstens Road, near the town of Midpines in Mariposa County, forcing thousands to flee. And on Sunday, crews continued to voice optimism in their bid to corral the blaze.

“We’re expecting to make good progress today,” said Capt. Jaswant Singh, a Cal Fire spokesman, on Sunday afternoon.

According to Cal Fire, the fire has destroyed 182 structures and damaged 10 more, and nearly 3,800 firefighting personnel have been deployed to get it under control. Additionally, more than 250 PG&E utility poles and accompanying equipment in the area will require replacement, leaving more than 450 customers without power as of 6 a.m. Sunday.

Road closures remained on Triangle Road at Darrah Road; the Lushmeadows area and Triangle Road toward Highway 140 are inaccessible as of Sunday. Jerseydale Road and its side roads remain closed. Residents have been granted access to Silva and Carleton roads, as well as Carstens Road.

An evacuation center remains in operation at Mariposa Elementary School, 5044 Jones St. in Mariposa. Authorities are also setting up a local assistance center for residents affected by the fire at the Mariposa High School gymnasium starting today and running through Wednesday from 9 a.m. to 7 p.m., at 5074 Old Highway N.
