The B.C. Wildfire Service says the Mount Underwood fire is displaying aggressive behaviour, forcing a nearby road closure. Meera Bains reports. “It grew massive,” said Huu-ay-aht First Nations Chief Councillor John Jack, chair for the Alberni-Clayoquot Regional District, speaking on CBC’s On The Island Tuesday morning.He noted the fire has grown larger than the nearby Wesley Ridge fire was at its height.The road between Bamfield, an unincorporated community with about 300 year-round residents, and Port Alberni is closed in both directions due to the wildfire, according to DriveBC.Jack said people are advised to use the Cowichan route if they need to get to the Bamfield area.Christi Howes, fire information officer with the B.C. Wildfire Service (BCWS) said there are no threats to Port Alberni or Bamfield at this time, but she stressed the need for people who are not residents to stay away from Bamfield.”We don’t want to add any additional pressures to the community by having extra people trying to get there, either by road or by trail,” she said.On Tuesday, the BCWS said the blaze was displaying Rank 4 and Rank 5 fire behaviour — meaning it was an extremely vigorous surface fire and burning to the tops of trees.Jack said residents of Bamfield and Anacla, a Huu-ay-aht First Nations community, are resilient and used to restricted access.”Being cut off from the Port Alberni area is always a bit of a concerning situation for them, but they’re no strangers to using gravel roads to get to where they need to go,” Jack said.”That being said, the power is out — and it’s out indefinitely. And that’s perhaps the most concerning thing.”In a 7:15 a.m. update Tuesday, B.C. Hydro said a crew had been assigned to the outage, but no time was given for when the power may return. It’s been down since about 6 p.m. Monday. The fire cut off power to more than 500 people near Port Alberni Monday evening. (Tseshaht First Nation/Facebook)Jack recommended residents be prepared by making a “72-hour kit,” having a plan for staying in place, and monitoring verified information sources.Howes said structural protection has been put in place for private campgrounds, mills and log-sorting facilities in the area.She said crews are expecting wind and rain in the forecast.”It’s a dynamic situation and we will be watching the weather very closely,” she said.The cause of the fire is under investigation.The Mount Underwood fire grows just after the Wesley Ridge fire, burning northwest of Nanaimo, was downgraded from “out of control” to “being held.”Howes said the Wesley Ridge fire remains “adequately resourced.”There are currently 97 active wildfires in B.C.ABOUT THE AUTHORLauren Vanderdeen is a web writer for CBC British Columbia.
