A wildfire burning in a rural area north of Miramichi has grown. As of Saturday afternoon, New Brunswick’s Department of Natural Resources (DNR) said the fire is now approximately 240 hectares. That’s up from 160 hectares Saturday morning, and 65 hectares Friday afternoon. “Fire protection has been placed around several camps and a communications tower as a precaution,” said DNR’s update Saturday. The wildfire broke out Wednesday and was initially estimated to be around 20 hectares. Highway 8 near Miramichi was shut down Friday around 5 p.m. between Route 450 and Oldfield Road due to the wildfire. At the time, New Brunswick RCMP said Russellville Road and McHardy Road were also closed, with traffic being diverted toward Neguac. “Over the next several days, the province is expected to remain under extreme fire weather conditions, with high winds, high temperature, and low humidity. It is a very dangerous situation with the state of fuels (ignitable materials in the forests),” said DNR. It said two skimmer aircraft from Quebec have arrived to assist that can “land on and scoop water from lakes or other bodies of water, then drop it on wildfires.” DNR also noted two fires that ignited on Friday in St. Paul and near Harvey are now under control. Meanwhile, the province is restricting some forestry operations due to the high wildfire risk. A provincewide burn ban also remains in place. The cause of the fire is under investigation.
