Residents of Thunder Bay are learning that Smoke in northwestern Ontario is expected to remain a challenge for the regional capital residents despite the temperaturedropping to a high of 25 Con Thursday.
“Smoke is obviously the biggest concern for people in northwestern Ontario because of the forest blazes to the northwest of Thunder Bay, and there’s good news and bad news,” stated Peter Kimbell, a notice preparedness meteorologist with Environment Canada. With an orange air quality notice in effect, Kimbell explained, the air is polluted and smoky, making it “hazardous for people’s health.” “People who are the most vulnerable are the very young, the very old [and] people with health conditions. So if at all possible, they should stay inside and wear masks." An orange advisory is released when the Air Quality Health Index is forecast to reach or has reached the highest-risk category (AQHI of 10+).
However, he remarked, there may be a slight improvement in air quality on Friday, as the wind might shift slightly to the south. “We also have a 60 per cent chance of showers in the forecast, which is also good because the precipitation tends to scour the atmosphere of the smoke particles." Nonetheless, Kimbell added, the wildfires are unlikely to go away, and if the wind shifts to the northwest again, the smoke would likely return. “The fire hazard is expected to remain high to extreme across the region over the next 36 hours,” noted Victoria Lee, an information officer with Ontario’s Aviation, Forest Fire and Critical incident Services (AFFES), in a written statement. “Hot, dry and windy conditions are forecast throughout northwestern Ontario and may contribute to increased fire behaviour and fire intensity on existing blazes.” Accommodations filling up as wildfires spur more evacuations in northwestern Ontario “Our focus continues to be on priority areas where fire suppression efforts are most likely to be successful, with top priorities being the protection of wildland firefighting personnel and public safety, critical infrastructure and capturing, where possible, new wildfires,” Lee declared.
“Generally, tomorrow [Friday] we probably would expect five, maybe 10, millimetres in some areas, but most areas won’t get very much,” Kimbell remarked, adding that localized thunderstorms may at most get 20 to 30 millimetres.
“Waterbombers and bucketing helicopters were active on multiple wildfires across the region yesterday [Wednesday], working to reduce fire intensity and slow fire growth.” “Several wildfires have grown significantly in the past 24 hours as dry, windy conditions in the northwest region persist,” Lee shared. “FireRanger crews, supported by waterbombers and bucketing helicopters, have had success suppressing smaller wildfires in parts of the region experiencing less intense fire behaviour.” “April was actually fairly wet in the northwest, but May was about 25 to 50 per cent below normal precipitation, and June and the first half of July have been even drier than that,” Kimbell indicated. “So it’s been very dry going forward, which is a very paramount part of why the forest blazes have started.” However, with the showers on Friday, he indicated, the Lakehead will have a high of 21 C as opposed to the warm temperatures of late. “Generally, tomorrow [Friday] we probably would expect five, maybe 10, millimetres in some areas, but most areas won’t get very much,” Kimbell remarked, adding that localized thunderstorms may at most get 20 to 30 millimetres. Despite the precipitation being welcome in the northwest to help put out the blazes, Kimbell advised against, it could trigger more thunderstorms. “Thunderstorms, if they occur, produce a lot of rain, but they produce a lot of rain in a very localized fashion,” Kimbell noted. “So they’re not always terribly helpful because they’re not over a wide area and they also carry the risk of igniting more forest blazes, which would generate more smoke.” While the community will have to see what happens Friday, he confirmed, Environment Canadadoesn't expect significant precipitation on a sustainable basis going forward. “Sunday, 30 per cent chance of showers, Monday, 40 per cent chance of showers, [but] no big dumps of a lot of rain. That’s what we need and we don’t see that in the future yet." Nicky Shaw is a reporter for CBC the Lakehead region.
