More hot weather forecast as Canada battles fires and smoke billows south
Canadian officials are warning of tough days ahead for fighting growing wildfires in Saskatchewan and Manitoba with hot and dry weather in the weekend forecast. The wildfires have forced thousands to evacuate in the two prairie provinces, with both this week declaring states of emergency.Smoke from the fires has triggered air quality alerts in Canada and as far as Chicago, where forecasters say the smell of smoke will be noticeable by Friday evening. There are also air quality advisories in place in parts of the US Upper Midwest, including Michigan, Minnesota, and Wisconsin.
"Conditions maybe unhealthy for sensitive groups and there is a possibility that hourly levels could reach the unhealthy range for a short period of time," the state of Michigan said on Friday. The advisories in Michigan and Wisconsin are currently in place through Saturday morning. Residents in northern Minnesota have been warned smoke could reach levels "unhealthy for everyone", with the rest of the state facing air quality that could effect those in sensitive groups. That alert runs through Monday evening. There are 15 wildfires burning in Saskatchewan as of Friday, with the Canadian Interagency Forest Fire Centre (CIFFC) classifying conditions in the province as extreme. Seven of those fires are not contained, according to data from the province.In Manitoba, there is a total of 22 fires burning, according to the province's fire situation report, with four classified as out of control. Thousands of people from 16 communities had been forced to evacuate in Saskatchewan this week as a result of the fires. Similar evacuations took place in Manitoba, affecting 17,000 people.All residents of Flin Flon, Manitoba, a community of about 5,000, have been told to leave by midday on Friday due to a large blaze threatening the town. Danielle Desjardins, a meteorologist with Environment and Climate Change Canada based in Winnipeg, told the BBC that the forecast for both provinces does not spell relief any time soon, with hot and dry conditions expected to continue into the weekend.
A cold front is expected to hit some parts of Saskatchewan, bringing with it some rain, but its current forecasted path narrowly misses the regions where the fires are burning."The bad news about this cold front is it's going to be windy," said Ms Desjardins, adding that the wind, coupled with the heat and lack of rain, are prime conditions for wildfire spread.She said Saskatchewan has been "extremely dry" since March, and is experiencing abnormally warm weather for May that has pushed temperatures to above 30C (86F). She added that anecdotally, "it's one of the worst (wildfire seasons) in recent years for Saskatchewan".How climate change worsens heatwaves, droughts, wildfires and floodsCanada experienced its worst wildfire season on record in 2023, when over 42 million acres (17.3m hectares) burned - an area larger than all of England - and more than double the previous record. Smoke from those wildfires blanketed cities south of Canada's border into the US, including New York City.But the 2023 fires were more acutely felt in Alberta, British Columbia, the Northwest Territories, Nova Scotia, Ontario and Quebec. This year, it is Saskatchewan and Manitoba that are seeing the largest fires to date.Fires happen naturally in many parts of the world. It is difficult to know if climate change has caused or worsened a specific wildfire because other factors are also relevant, such as changes to the way land is used.But climate change is making the weather conditions needed for wildfires to spread more likely, the IPCC, the UN's climate body, says.

Air quality alerts in Minnesota due to Canadian wildfire smoke
An air quality emergency has been issued in a Minnesota city, warning residents that any exposure could lead to serious health effects. Minneapolis and its suburbs are currently experiencing 'Very Unhealthy' air due to toxic wildfire smoke drifting in from Canada. Several large wildfires have been burning across British Columbia, Saskatchewan, and Manitoba over the past week. Blaine, a suburb, currently has the worst air quality in the United States, followed by nearby Saint Paul, Minneapolis and Savage. More than 3.6 million Americans are under the alerts. All of Minnesota is under some level of air quality alert, which officials say will remain in effect through midday Wednesday. Meteorologists warn that due to the size and scope of the Canadian wildfires, Minnesota is likely to face intermittent smoky skies for several more days. Smoke from over 160 active Canadian wildfires is also creating public health concerns in Wisconsin, Iowa and Nebraska. These areas are experiencing conditions classified as from 'Unhealth' to 'Unhealthy for Sensitive Groups,' posing risks to pregnant women, children, the elderly, and those with respiratory conditions. The US Air Quality Index (AQI) considers a value of 50 or below to be 'good' air quality. But current readings in Blaine have reached 253, placing it deep in the 'Very Unhealthy' range. Saint Paul sits at 234, Minneapolis at 210, and Savage at 204, all of which are also hazardous to health. These elevated levels are expected to persist through Tuesday afternoon, before gradually dropping into the 100s, a range still considered 'Unhealthy for Sensitive Groups,' through Wednesday. The official air quality forecast indicates that conditions are expected to improve to healthy levels by Thursday. Eastern Iowa, from Burlington to Maquoketa, is currently experiencing unhealthy air quality, according to the Iowa Department of Natural Resources. Parts of northern and western Iowa are listed under a moderate air quality ranking. The region's AQI is ranging from 151 to 200, while moderate levels sit from 51 to 100. Meteorologists said showers and thunderstorms are expected in the coming days that will push some of the smoke out of the area. Brooke Hagenhoff, a National Weather Service meteorologist in Des Moines, told Des Moines Register : 'With this incoming system, that's going to help push a lot of the smoke off to the east, so with that we should start to see improvement as far as the haziness in the sky the past several days.' The wildfire smokes is also concentrating in a small region of Nebraska around Blair and Blakely Township where levels are 'Unhealth for Sensitive Groups.' The Canadian province of Manitoba declared a state of emergency on Wednesday, triggering mass evacuations in the area. Manitoba Premier Wab Kinew said: 'This is the largest evacuation Manitoba will have seen in most people's living memory.' 'The military is being called for help here because of the sheer scale of the 17,000 folks that we move relatively quickly.' So far this year, Manitoba has had 102 fires, which officials say is 'well above' the province's average of 77 by this time. Separately, wildfires in Alberta province have prompted a temporary shutdown of some oil and gas production and forced residents of at least one small town to evacuate . That region was affected on Wednesday by wildfires spanning 11.2 square miles near Chipewyan Lake, a small community in the northern part of the province approximately 81 miles west of the oil sands hub of Fort McMurray.

Canadian wildfire smoke spreads into US Midwest
DULUTH, Minnesota, June 3 (Reuters) - Smoke from wildfires burning in three Canadian provinces is spreading into the U.S. Upper Midwest, stirring memories of the severe pollution that drifted south from Canada two years ago during that country's worst fire season on record. The particulate matter pollution caused by the smoke is already drifting into Minnesota and neighboring states. It is expected to make its way to New York and other East Coast cities in coming days, posing a health risk to the tens of millions who live in those regions. "Airborne particulate matter is the most serious environmental health risk we know of," said Doug Brugge, a public health researcher at the University of Connecticut School of Medicine. "It causes cardiovascular, respiratory and neurological harm, and these plumes of smoke are at very high levels compared to what we're usually exposed to in the U.S." Scores of wildfires have swept across Canada since the start of May, forcing thousands of evacuations and disrupting crude oil production in the country. There were more than 200 active fires as of Monday, 106 of which were out of control, according to the Canadian Interagency Forest Fire Centre. So far, 1.9 million hectares (4.7 million acres) have burned, mostly in the provinces of Alberta, Saskatchewan and Manitoba. Still, the current crisis does not yet come close to rivaling 2023, when 17 million hectares burned. One of the worst spots in the U.S. for air quality on Tuesday morning as a result of the fires was Ely, Minnesota, near the Manitoba border. It registered a "hazardous" air quality index reading of 336, according to IQAir, a website that monitors air quality around the world. An air quality rating of below 50 is considered to be "good," and readings between 100 and 300 are deemed "unhealthy" to "very unhealthy," while higher than that is considered "hazardous," according to the website. In Duluth, Minnesota, the rating stood at 309 at midmorning Tuesday, while in Flin Flon, Manitoba, about 800 miles (1,300 km) to the north and in one of the areas where the Canadian wildfires are concentrated, the AQI was at 359. In IQAir's list of the world's major cities, Minneapolis ranked as second worst air quality, with a 210 reading, trailing only Kuwait City, which led the list with a 318 reading. Children, the elderly and people with chronic cardiac, respiratory and other illnesses are most vulnerable to the effects of the smoke, especially those with cardiovascular problems, according to Brugge. "The risk of hospitalization and death is low in people who are healthy and at a young age," he said, adding that there is still evidence that air pollution exposure increases blood pressure and inflammation for those people. Experts have said that particulates from wildfire smoke enter most buildings in high concentrations, although the problem is greater in older structures. The concentration of wildfire pollutants indoors is on average about half of what it is outdoors, but if a building is not well sealed, the concentration may be up to 70% of what it is outside, experts have said. The U.S. Environmental Protection Agency advises that during wildfire smoke events, people avoid indoor activities that put more fine particles into the air, such as smoking cigarettes, frying or broiling food, burning candles or incense, and vacuuming without a HEPA filter. Exposure to wildfire smoke may also increase lung cancer patients' risk of dying from their disease, particularly among non-smokers, although the effect may be mitigated by certain cancer treatments, according to a large California study presented last month. Nonetheless, some farmers believe the effects of the fires are not all negative. In online forums like Facebook, some farmers have said some of their best yields ever came from years with a heavy pall of wildfire smoke from Canada. The smoke can protect vulnerable crops from scorching sunlight, they think.
