Firefighters stopped the spread of two wildfires Monday in Northern California’s wine country, while authorities downgraded an evacuation order near Santa Rosa to a warning.

The Hardin Fire burned 55 acres near Hardin and Pope Canyon roads in Napa County’s Pope Valley, according to the California Department of Forestry and Fire Protection. Firefighters stopped its forward progress by 5:10 p.m., and the fire was 35% contained.

No evacuation orders or warnings were reported for the Hardin Fire.

About 25 miles southwest, the 14-acre Ledson Fire remained 10% contained near Highway 12 and North Pythian Road, east of Santa Rosa.

The Sonoma County Sheriff’s Office ordered residents in evacuation Zone SON-3H3 to leave. The order remained listed as active on Cal Fire’s incident page as of 4:05 p.m.

An evacuation order for Zone SON-3H3 was downgraded to a warning by Monday evening. Under the warning, people who need additional time to leave – including those with pets or livestock – were advised to evacuate.

Firefighters had stopped the Ledson Fire’s forward progress and placed hoses around its perimeter. Crews continued strengthening containment lines after air tankers and bulldozers helped surround the flames.

No injuries or structural damage had been reported in either fire as of Monday evening.

The causes of both fires were under investigation.

The fires broke out before a heat advisory scheduled to take effect Tuesday across the North Bay’s interior mountains and valleys.

The National Weather Service forecast widespread highs in the 90s, with some locations reaching the low 100s. The advisory was scheduled to remain in effect until10 p.m. Tuesday.
