Massive wildfires near Clinton merge, forming Big Bar complex and generating own weather system.

Four wildfires near Clinton, British Columbia have merged into a single massive complex — and it is now large enough to create its own weather, according to BC Wildfire Service. The combined fires, now called the Big Bar complex, cover an estimated 88,812 hectares across the Thompson-Nicola and Squamish-Lillooet Regional Districts.
The complex includes the Pear Lake, Fiftynine Creek, French Bar Creek, and Bonanza Creek wildfires. Fires of this size can generate pyroconvective activity — meaning the heat creates its own wind, clouds, and lightning, making them far harder to control, Abbotsford News reported.
The Fiftynine Creek fire has reached Highway 97 near Chasm, a small community north of Clinton. The fire jumped previously established containment lines and is actively burning close to the road. It is also pushing northward, raising concerns about further spread along the highway corridor, according to North Delta Reporter.
Highway 97 is one of British Columbia's main interior routes. Any disruption there can affect travel and supply chains across a wide area. Officials have not yet confirmed whether the highway has been fully closed, but the fire's proximity to it remains a serious concern.
The Village of Clinton has suffered confirmed structure losses from the fire complex. The exact number of affected properties has not yet been assessed, The Progress reported. Crews and officials are still working to get a full picture of the damage.
The Pear Lake fire is expected to keep growing. Severe drought conditions in the area are drying out vegetation, giving the fire more fuel. Drought makes fires burn hotter, spread faster, and become harder to stop with standard firefighting methods.
At 88,812 hectares, the Big Bar complex is large enough to behave like a weather system. Intense heat from a fire this size pushes air rapidly upward, forming tall columns of smoke and cloud. This can produce unpredictable wind shifts, dry lightning, and firebrands that spark new ignitions far from the main fire, according to Mission City Record.
These self-generated weather effects make firefighting far more dangerous and unpredictable. Crews can lose containment lines quickly when winds suddenly change direction. The BC Wildfire Service is actively monitoring the complex as conditions remain extreme across the region.
The Bonanza Creek wildfire, burning in the Squamish-Lillooet Regional District, is the fourth fire folded into the Big Bar complex. Its inclusion stretches the fire's footprint across two regional districts, complicating coordination between local emergency teams, Castlegar News noted.
Evacuation orders and alerts are in place across affected areas. Residents are urged to follow updates from their local emergency programs. The BC Wildfire Service has not yet given a containment timeline for the complex given the active and rapidly changing conditions.
