Erratic winds, lightning make Boston Bar firefighting efforts challenging

Hot, windy weather and the threat of dry lightning have made firefighting efforts near Boston Bar in B.C.'s Fraser Canyon more dangerous, the wildfire service says.

B.C. Wildfire Service (BCWS) information officer Julia Carinci said challenging weather conditions are increasing the risk to those working on both the Brunswick Creek and Ainslie Creek wildfires. known together as the Brunswick complex.

"Right now, for the safety of our crews, we are going to switch our tactics for the next 24 to 48 hours and focus primarily on structure defence and protection," said Carinci. "So, moving away from the flanks of the fires that are active for the safety of our crews."

'Up in flames'

Fernando Valanta, who was staying at a friend's house in Boston Bar, said the fire near town exploded in size over night.

"What we saw last night was an entire mountain disappearing in front of our eyes in minutes, trees looking like Q-Tips doused in gasoline just going up in flames," he said.

Valanta left when the evacuation order was issued, ending up at the evacuee reception centre in Chilliwack.

"As we were heading toward Hell's Gate, we could see the end of it. It was scary," he said. "The last couple of days, the way things have been unfolding, everyone was on edge. Everyone is concerned for their house."

An area motel owner told CBC News the smoke is so thick around Boston Bar that, at times, it's impossible to breathe.

Gurvinder Badyal said her Canyon Alpine Motel, which is outside the evacuation zones, is hosting 35 firefighters.

"We have sprinklers on our property and on the adjacent property," she said. "It's scary and safe at the same time. The [Ainslie Creek] fire has moved to the other side of the mountain from us. So we're feeling safer."
