Major fires expanded rapidly Tuesday, driving evacuations from Canada’s Okanagan region to communities near California’s Big Sur coast.
PENTICTON, BRITISH COLUMBIA — Fast-growing wildfires in British Columbia and California expanded dramatically Tuesday, forcing thousands of people from their homes and stretching firefighting resources as hot, dry conditions complicated efforts to slow the flames.
The most serious emergency was unfolding in British Columbia, where the Bald Range wildfire had burned about 156 square kilometers, or 60 square miles, near Okanagan Lake after starting Aug. 7. About 20,000 people fled affected communities, including Summerland and Peachland, while officials confirmed that an 80-year-old woman died while trying to escape the fire in the Meadow Valley area. Homes and other properties have been destroyed, but authorities said dangerous conditions have prevented a complete damage assessment.
The fire’s rapid spread prompted British Columbia to declare a provincial state of emergency Aug. 8. Provincial officials said stronger winds pushed the fire into the Summerland area shortly after it began, causing significant property losses and leaving some people temporarily isolated behind the fire perimeter. Summerland, a community of roughly 12,000 people about 185 miles east of Vancouver, remained heavily affected as firefighters worked in steep terrain where burning embers were starting new fires beyond the main perimeter.
About 100 firefighters from Mexico were expected to arrive Tuesday to reinforce crews already battling the Bald Range fire. Roughly 100 wildfires were burning across British Columbia, with about half considered out of control, according to provincial fire officials. Authorities were also watching for additional lightning-caused fires in the central Interior and Okanagan region. The province has arranged more than 1,000 hotel rooms in Penticton, Kelowna and West Kelowna for evacuees, along with nearly 1,000 group-lodging beds.
Farther south, California was confronting several rapidly expanding fires. The Bug Fire, burning in Lassen and Sierra counties near the Nevada line, had grown to 44,304 acres by Tuesday morning and was only 4% contained. The fire had been listed at 16,680 acres Monday evening, meaning its mapped footprint more than doubled overnight. Evacuation orders and warnings remained in effect in neighboring Washoe County, Nevada. The fire started Saturday afternoon east of U.S. Route 395 and south of Bringman Road, and its cause remained under investigation.
The Bug Fire’s growth has been particularly sharp since it was first reported at about 50 acres Saturday. Within hours it had reached thousands of acres, and by Sunday evening officials placed it at 11,405 acres. By early Monday it had reached 15,000 acres before another major increase was recorded overnight. The Bureau of Land Management’s Carson City District has jurisdiction over the fire, while California authorities are also posting updates because the blaze involves Lassen and Sierra counties.
Along California’s central coast, the Timber Fire near Big Sur also continued to grow. The fire was mapped at 2,000 acres Tuesday morning with 5% containment, up from 800 acres early Monday. It began Sunday southeast of Loma Vista in Monterey County and has burned through steep, rugged terrain that has made access difficult for ground crews. Nearly 500 personnel, along with helicopters, engines, bulldozers and water tenders, were assigned to the response.
Evacuation orders remained in place for several zones along the Big Sur coast, while additional areas were under warnings. State parks in the Big Sur area were closed, and an evacuation shelter and temporary evacuation point were operating at Carmel Middle School. Firefighters said the blaze remained east of Highway 1 Tuesday morning. Crews concentrated on protecting structures near the highway in the Ventana area while cutting brush, setting up water systems and securing routes for emergency equipment.
Firefighters faced additional complications overnight near Big Sur because a heavy marine layer limited helicopter visibility at lower-elevation water sources. Officials said the northern and eastern sides of the fire remained active, with isolated trees torching and flames making uphill runs. Warmer and drier conditions were expected over the eastern part of the fire during the first half of the week, while a small chance of thunderstorms was forecast for Wednesday afternoon and evening. The cause of the Timber Fire remained under investigation.
The emergencies come during an active August fire period across western North America. California listed more than a dozen active incidents Tuesday, including the 10,339-acre Gann Fire in Calaveras County and the 2,410-acre Antelope Fire in Kern and San Luis Obispo counties. State officials said vegetation will continue drying through the summer, with normal to above-normal significant-fire potential expected in parts of Northern California through September.
Fire crews in both countries remained focused Tuesday on containment, evacuations and structure protection. British Columbia authorities had not completed a full assessment of losses around the Bald Range fire, while the Bug and Timber fires remained only lightly contained. Officials said changing weather, dry vegetation and difficult terrain could continue to affect firefighting operations as crews work to keep the fires from spreading into additional communities.
