Code Orange air quality alert declared for southwestern Pennsylvania on Thursday
Officials say hazy sunshine through low-level Canadian wildfire smoke, high temperatures and light southwest winds will produce significant ozone concentrations.
On air quality action days, young children, the elderly, and those with respiratory problems, such as asthma, emphysema, and bronchitis, are especially vulnerable to the effects of air pollution and should limit outdoor activities.
Residents and businesses within the Air Quality Action Day areas are strongly encouraged to voluntarily help reduce ozone air pollution by:
Driving less by carpooling or using public transportation;
Combining errands to reduce vehicle trips;
Limiting engine idling;
Refueling cars and trucks after dusk; and
Conserve electricity by setting air conditioning to a higher temperature and turning off lights that are not in use.

Map Shows Flash Flood Threat Affecting Millions on Friday
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. National Weather Service (NWS) meteorologists have warned that millions of people across three states are at risk for heavy rain that could lead to flash floods on Friday. Why It Matters On Thursday, torrential rain pummeled the Northeast, prompting the governors of New York and New Jersey to declare states of emergency as flash floods overwhelmed busy roads at peak travel time. Now, although much of the U.S. is expecting some sort of rainfall on Friday, the heaviest downpours are shifting south. What To Know On Thursday night, the NWS posted a map on Facebook showing the main weather threats, which included flash floods, facing the U.S. on Friday. "Scattered thunderstorms and heavy rainfall are expected to bring the potential for flooding across the Carolinas, Southern Plains, and the front-range of the Rockies on Friday," the post said. "Fire weather concerns will persist in the northwestern Great Basin on Friday due to isolated dry thunderstorms. Air quality will continue to be impacted through Saturday in the Midwest due to smoke from the Canadian wildfires." A map from the National Weather Service shows the most likely areas for flash flooding on Friday are in Texas and the Carolinas. A map from the National Weather Service shows the most likely areas for flash flooding on Friday are in Texas and the Carolinas. National Weather Service According to the map, all of South Carolina, much of North Carolina and east-central Texas had the highest risk of seeing rainfall heavy enough to cause flash floods. Meanwhile, rain and thunderstorms are expected across the Pacific Northwest, central U.S., South and Northeast. Despite the forecast, the only flash flood warning in place on Friday morning around 10:30 a.m. Eastern time was for the Tulsa, Oklahoma, forecast region. Bob Oravec, the lead forecaster at the NWS Weather Prediction Center, told Newsweek that heavy rain could begin in the Carolinas in the early afternoon, with thunderstorms peaking between 6 to 8 p.m. In Texas, the storms are expected to begin later in the night and peak around 3 or 4 a.m. Saturday. "The risk has definitely pressed southward from where it was yesterday," Oravec said. "Right now, there's really not much on the radar, but as the afternoon goes on there's a frontal boundary that's lying across central southern North Carolina into northern South Carolina that will be the focusing mechanism for the thunderstorms this afternoon." What People Are Saying A National Weather Service forecast issued on Friday said: "A front extending from the southern Mid-Atlantic southwestward to the Southern Plains will move southward to northern Florida westward across the Gulf Coast and then northwestward across Texas to the Southern High Plains by Sunday. "The front will trigger showers and thunderstorms, accompanied by heavy rain, over parts of the southern Mid-Atlantic. ... The associated heavy rain will primarily create localized areas of flash flooding, with urban areas, roads, small streams, and low-lying areas being the most vulnerable." The forecast continued: "Additionally, showers and thunderstorms with heavy rain will develop along and near the boundary over parts of the Southern Plains and Southern High Plains. Therefore, the WPC has issued a Slight Risk (level 2/4) of excessive rainfall over two areas of the Southern Plains and Southern High Plains through Saturday morning. The associated heavy rain will primarily create localized areas of flash flooding, with urban areas, roads, small streams, and low-lying areas being the most vulnerable." What Happens Next Rain is expected to continue across the U.S. throughout the weekend. Residents in the high-risk areas should monitor local weather guidance as the storms arrive.

Millions Urged To Monitor Wheezing, Dizziness
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. Air quality alerts were in effect for nine states on Friday, with officials urging residents in some affected areas to monitor for potential health effects caused by pollution. Why It Matters According to the Environmental Protection Agency (EPA), studies have linked particle pollution exposure to various health effects, including respiratory symptoms—such as coughing and wheezing, the development of asthma and increased susceptibility to respiratory infections. Regarding ozone pollution, the EPA says exposure to ozone may irritate the respiratory tract, cause airway inflammation and aggravate existing conditions—such as asthma, emphysema and chronic bronchitis. What To Know The alerts spanned the entirety of Minnesota, Wisconsin, Michigan, Illinois and Iowa as well as an eastern portion of Nebraska and the St. Louis metropolitan area in Missouri because of smoke from wildfires in Canada. "Monitor for symptoms such as wheezing, coughing, chest tightness, dizziness, or burning in nose, throat, and eyes," an alert relayed by the National Weather Service (NWS) said. "Reduce or eliminate activities that contribute to air pollution, such as outdoor burning, and use of residential wood burning devices," it continued. In Minnesota, local authorities said northerly winds would carry heavy smoke from wildfires across Manitoba and Saskatchewan into the state, lingering through Saturday afternoon, when some improvement was forecast. Meanwhile, air quality alerts had been issued for Colorado and Texas because of ozone pollution. These covered Colorado's Douglas, Jefferson, Denver, western Arapahoe, western Adams, Broomfield, Boulder, Larimer and Weld Counties. In Texas, the Dallas-Fort Worth area was affected. In Colorado, ozone concentrations that were potentially unhealthy for sensitive groups—including children, older adults and those with preexisting medical conditions—were most likely from the western suburbs of Denver, northward along the foothills and the I-25 urban corridor to the Fort Collins area, officials said. In Texas, weather conditions were predicted to be conducive to high levels of ozone air pollution in the Dallas-Fort Worth area. Residents were advised to take steps to help prevent pollution, such as reducing vehicle use. What People Are Saying The National Weather Service in Omaha/Valley, Nebraska, wrote on X on Thursday: "The hazy skies today are a result of Canadian wildfire smoke, which is expected to linger in the area through Friday afternoon. The smoke is leading to moderate to unhealthy air quality, especially for sensitive groups." NWS Chicago wrote on X on Thursday: "Poor air quality due to wildfire smoke is expected to continue through tomorrow and will be at unhealthy levels for everyone in some locations. Consider limiting prolonged outdoor activity." NWS Twin Cities, Minnesota, wrote on X on Wednesday: "Wildfire smoke sticks around through the beginning of the weekend, before storm chances return late Sunday into Monday." AccuWeather meteorologist Brandon Buckingham previously told Newsweek: "Ozone is a secondary pollutant, meaning it's not emitted directly from sources, but is formed through chemical reactions. These reactions require sunlight and higher temperatures, making warmer months more prone to ozone formation. When air is stagnant, pollutants don't get dispersed, allowing ozone to build up to unhealthy levels." What Happens Next At the time of writing, the latest of the alerts were in effect through Saturday. The NWS issues regular forecast updates on its website.

Chicago, Minneapolis smothered with worst air quality in world as Canadian wildfire smoke returns
Several wildfires burning across the northwestern Canadian provinces are again sending vast amounts of smoke into the upper Midwest and northeastern US, swamping the area with unhealthy air quality – some of the worst in the world, according to some metrics. Northerly winds began pushing smoke south into Minnesota, Wisconsin and Michigan on Thursday. Advertisement Air Quality Alerts are in effect for Iowa, Minnesota, Michigan, Wisconsin, Missouri, Illinois and northern Indiana, covering more than 100 million Americans in major cities such as Minneapolis, Chicago, Milwaukee and Detroit. Photos from Minneapolis early Thursday morning showed a thick haze blanketing the region. Air quality indices in Wisconsin have pushed into the 'very unhealthy' range and are now some of the unhealthiest in the nation as of late Thursday morning, according to IQAir. On Thursday morning, six of the top 10 worst air quality readings in America were all in Wisconsin. Advertisement And as of 11:30 a.m. CT, Chicago and Minneapolis had two of three of the worst air quality indices in the world among major cities, according to IQAir. Purple or very unhealthy air quality means that anyone could experience difficulties when being outside for any period of time. 3 Air quality alerts issued through Saturday. Fox Weather 3 Chicago had the worst air quality in the world for a few hours on Thursday. WGN News / YouTube Advertisement 3 The air quality is expected to improve this weekend. WGN News / YouTube The FOX Forecast Center said by Friday, the smoke will push further even south into Illinois, Missouri and will also impact the interior Northeast. In addition to reducing air quality, the smoke may decrease visibility in some areas. Air quality in Minnesota and Wisconsin is expected to improve by Saturday. Advertisement The fires burning in Saskatchewan, Alberta and Manitoba have been ongoing all summer, and it's not the first time the smoke has pushed south into the US this summer. Just last week, smoke from the wildfires impacted air quality in the Northeast, where air quality alerts were posted in New York City and Boston.
