Update: Hardin Fire Containment Grows As Heat Intensifies Today In Napa Valley

NAPA VALLEY, CA — Firefighters gained the upper hand on the Hardin Fire Tuesday, increasing containment to 65 percent after the wildfire scorched 79 acres near Hardin Road and Pope Canyon Road in Napa County, according to CAL FIRE.

Crews will continue reinforcing containment lines and extinguishing remaining hot spots as temperatures are expected to approach or exceed 100 degrees.

Forty firefighters were assigned to the fire this morning, supported by five engines, one hand crew, and two water tenders.

The Hardin Fire ignited about 2:40 p.m. Monday near Hardin and Pope Canyon roads in Pope Valley and spread rapidly through dry grass before firefighters launched an aggressive ground and air attack.

Crews increased containment after the fire grew from early estimates of 30 to 40 acres to its final mapped size of 79 acres on Monday, CAL FIRE reported.

Authorities temporarily closed Silverado Trail near Highway 128 during the firefighting effort. Fire officials have not determined the cause of the fire, and no evacuation orders or warnings were issued.

The Hardin Fire was one of two wildfires that challenged firefighters in the North Bay on Monday. In neighboring Sonoma County, the Ledson Fire reached 45 percent containment by Tuesday morning after prompting evacuation orders for hundreds of residents in Kenwood.

The fire burned near North Pythian Road at the northern end of Sonoma Valley on the western slopes of the Mayacamas Mountains, just west of the Sonoma-Napa county line, where crews battled flames spreading across steep terrain before gaining the upper hand overnight.
