CALISTOGA, Calif.—Firefighters in Northern California on Tuesday struggled to make headway against two wildfires, one of them threatening wineries and towns in the Napa Valley, and a second that killed three people closer to the Oregon border.

The three fatalities in the so-called Zogg Fire in Shasta County, about 200 miles (322 kms) north of San Francisco, were reported by the local sheriff.
