Chicago weather: Air quality alert called for a 2nd straight day as Canadian wildfires continue
An air quality alert is in effect until midnight Thursday for the Chicago area as Canadian wildfires continue, officials said.
The Illinois Environmental Protection Agency declared an Air Pollution Action Day because widespread ozone and or particulate levels are expected to be at or above the unhealthy for sensitive groups category.
Officials said wildfire smoke is expected to continue to affect those levels Thursday and Friday, officials said. The same air alerts were also issued on Wednesday.
Current morning conditions at O'Hare International Airport are mostly cloudy with haze at 60 degrees. At Midway Airport, conditions are foggy and misty at 61 degrees.
On Thursday, highs in the upper 50s are expected.
Plumes of smoke are blanketing large swaths of the U.S. and parts of Europe, which presents risks for those breathing it.
The Midwest, Northeast and Great Lakes regions of the U.S. have 'very unhealthy' air quality, according to the Environmental Protection Agency, and experts say people should take precautions. Read more here.

Wildfires force another 1,000 residents from their homes in the Canadian province of Manitoba
WINNIPEG, Manitoba (AP) — Wildfires forced another 1,000 people to flee their homes in Manitoba, one of two Canadian provinces under a state of emergency that has led to thousands of evacuations. Smoke from Canadian wildfires has worsened air quality in eastern Canada and the U.S. The fires have forced thousands of Canadians to flee their homes and sent smoke as far as Europe. The town of Snow Lake, Manitoba issued a mandatory evacuation order for its residents Friday as a large wildfire threatens the area. That fire, which has now grown to more than 3,000 square kilometers (1,058 square miles), has already forced out all 5,000 residents of the city of nearby Flin Flon and a thousand more in surrounding cottages and homes. When the Snow Lake evacuees are added in, Manitoba has about 19,000 displaced from their homes. There are 27 total fires in the province of Manitoba, eight of them out of control. Manitoba Premier Wab Kinew said evacuees have found a place to stay with friends or family, in hotels or in congregate shelters. Saskatchewan Premier Scott Moe, premier of the neighboring province, said two people were charged with setting wildfires. He said one of them was charged in relation to a fire around La Ronge, Saskatchewan, which has forced 7,000 people to flee their homes. There are 24 active wildfires burning in the province of Saskatchewan, forcing between 10,000 and 15,000 people from their homes. 'Many if not virtually all of the fires that we're dealing with in Saskatchewan, although not intentionally, are human caused. Some of those have been intentionally human caused,' Moe said. The province is also under a state of emergency, making it easier for different levels of government to coordinate a response. Moe said they are in daily contact with the federal government but have not yet asked for the military to help airlift out evacuees as they have so far been able to get them out by road.

Trump's immigration, trade policies could cost tourism industry $12B: report
The US economy could lose out on billions of dollars this year as President Trump's policies hamper the tourism industry, according to a report. The administration's mass deportation efforts, costly trade war, anti-LGBTQ legislation and, most recently, a travel ban on 12 countries have hammered foreign arrivals and spurred anti-US boycotts. The backlash from foreign visitors is expected to cost the US economy a whopping $12.5 billion this year, according to the World Travel & Tourism Council. Advertisement However, the organization's estimates have been vastly off the mark in the past. It predicted that growth in the country's travel sector would slow significantly in 2017 after Trump's surprising first election victory, but the number of visitors actually jumped amid a worldwide upswing in tourism. 3 The US economy could lose out on billions of dollars this year as the tourism sector is hammered by policy changes. AP Though Trump has made clear his frustrations with the trade deficit, the projected decline in tourism would only worsen the issue, as spending by foreign visitors in the US is counted toward our exports, according to a Bloomberg report. Advertisement The White House did not immediately respond to The Post's request for comment. Foreign arrivals to the US by air have plunged 2.5% so far this year through April compared to the year before, according to the US International Trade Administration. The largest drop came in March, when arrivals fell 10% after Trump unveiled hefty tariffs on Canada, China and Mexico. Those tariffs, combined with Trump's call to annex Canada as the 51st state, have prompted frustrated Canadians to call for a travel boycott and to stop buying US products. Advertisement Figures on Canadian tourism have not been released by the US yet, but Canada's statistics bureau said trips across the border tumbled 15% in April for the third straight month of decline. Research firms have scaled back their expectations for US tourism this year since Trump took office. Tourism Economics now expects just 66 million visitors – above previous expectations of 79 million – as policy changes prompt travelers to book trips elsewhere, according to Bloomberg. 3 Venezuelan migrants arrive after being deported from the United States at Simon Bolivar International Airport. REUTERS The largest reversal will likely come from Canadians, with visits expected to plunge 20% this year, followed by a nearly 6% drop from western Europe, Tourism Economics said. Advertisement Air carriers like Air France, British Airways and Lufthansa have started to cancel long-haul flights to popular US cities while travel sites like Airbnb, and Expedia have warned that their earnings could be hit hard this year. At least a dozen foreign nations have advised their citizens to use caution when traveling to the US due to the risk of being detained by immigration officials. Others have warned transgender and nonbinary citizens that they could run into trouble using their passports after Trump signed an executive order recognizing 'male' and 'female' as the only two sexes. Global air bookings to the US from May 1 to July 31 are 11% lower than the same time last year, according to Tourism Economics. 3 President Trump departing the White House on Friday for a weekend trip to New Jersey.

The US is the only economy expected to suffer a tourism revenue decline this year out of the nearly 200 economies tracked by the WTTC.

With record-breaking snowmelt, is the western US at risk for wildfires like those in Canada?
DENVER – A rapid snowmelt across the western United States is setting records for how quickly the frozen precipitation is disappearing and also raising alarms about future wildfire activity. According to the National Integrated Drought Information System, many mountainous regions in states such as Colorado, Utah, Nevada, and New Mexico saw near- to above-average snowfall, but now many of the same basins are experiencing drought. The rapid loss of snowpack, combined with elevated evaporation rates, can quickly dry out soils and vegetation, creating ideal conditions for wildfires. "Snowmelt this time of year is common, but such rapid melt rates are not normal," experts with NIDIS stated. "In some instances, above-normal temperatures such as these can cause snow to sublimate (transition from a solid to a gas) and reduce runoff into streams and reservoirs." Examples of snowless mountains include Wolf Creek Pass in Colorado and Baldy Mountain in Arizona. Canadian Wildfires Bring Poor Air Quality, Hazy Skies, Red Sunsets Across Central, Eastern U.s. Large sections of Canada have also seen a shorter snowmelt period, which has coincided with an uptick in wildfire activity. According to the Canadian Interagency Forest Fire Centre, more than 200 wildfires continue to burn across the country, with nearly 6.4 million acres destroyed since the beginning of the year. While the figures appear to be staggering, they are still far short of 2023, when some 37 million acres burned, setting records for the country's worst fire season on record. The previous record-breaking season led to significant smoke infiltration of the U.S., impacting air quality readings for millions of residents across North America. Similar plumes of smoke have been observed during recent weeks, but due to the jet stream, most of the particles have remained elevated well above the surface. A pattern shift would undoubtedly allow more of the hazardous air to reach the surface, leading to health concerns in addition to visibility issues. With a lack of snow and fire dangers increasing across the western U.S., it might only be a matter of time before firefighters are racing to contain wildfires from the Desert Southwest to the Northern Rockies. Because of the general west-to-east wind flow across the U.S., any large wildfire that pops up in the West naturally sends smoke eastward, potentially impacting a large chunk of the country. Before And After Images Show The Extent Of Wildfire Damage Around Los Angeles So far, the U.S. has been experiencing only an average wildfire season, but some of the worst months are still ahead. According to the National Interagency Fire Center, 1.2 million acres have burned in 2025, which is below last year's figure, which was in excess of 2 million through the first five months of the year. Outside of Florida, most counties facing drought conditions are in the western U.S., with nearly a third of the nation officially in significant deficit, according to data from the U.S. Drought Monitor. As the calendar year heads deeper into summer, forecasters expect drought conditions to expand in many locations west of the Mississippi River, including in the Northern Plains and throughout article source: With record-breaking snowmelt, is the western US at risk for wildfires like those in Canada?
