Police said the Meadow Valley resident was leaving with a family member when she reportedly died suddenly. The RCMP confirmed her death was connected to the Summerland, or Bald Range, wildfire and said no other fatalities were known at that time. David Eby, the premier of British Columbia, expressed deep sadness over her death.

The fire began on Friday near Okanagan Lake and expanded rapidly. By late Sunday it had burned more than 13,600 hectares, equivalent to 33,600 acres, according to the BC Wildfire Service. Officials classified it as out of control.

The speed and reach of the incident required evacuations by air as well as by road. Emergency workers airlifted 50 people to safety on Saturday as overnight evacuation orders spread, CTV News reported. The provincial emergency came while firefighting teams were managing a large number of other incidents: more than 100 wildfires were active across British Columbia as of late Sunday.

Prime Minister Mark Carney thanked firefighters and other emergency personnel for sustained work to protect communities. He said the federal government was prepared to assist British Columbia and expressed concern for residents who had been forced from their homes.

Forecast conditions created the possibility of further outbreaks. The wildfire service warned of a high likelihood of lightning-caused ignitions, particularly in the central Interior and the Okanagan. Those areas were receiving little rainfall along with dry lightning, a combination capable of starting fires without providing enough precipitation to slow them.

Researchers with World Weather Attribution had previously assessed the broader fire season. They found that climate change driven by human activity doubled the likelihood of the extreme fire conditions behind Canada's wildfires that year. That assessment concerned the conditions supporting the season, rather than serving as a direct determination of how the Summerland fire began.

The woman's death placed a human toll alongside the evacuation and land-area figures. She was attempting the same departure required of tens of thousands of residents when she died, while another 50 people needed aircraft to escape.

With the Summerland fire still uncontrolled, officials faced simultaneous demands: protecting evacuated communities, containing a blaze already covering more than 13,600 hectares and preparing for lightning that could ignite additional fires. The absence of other reported deaths did not lessen the continuing danger to residents, responders and property across the affected region.
