Smoke from Canada wildfires prompt air quality alerts in US: See map
Over 750 wildfires are burning throughout Canada, with more than 500 labeled out of control, according to the Canadian Interagency Forest Fire Centre. Over 16 million acres of land have been scorched by blazes, making this year's wildfire season one of Canada's worst on record.
Smoke from the blazes has crossed into the United States, bringing hazy skies to multiple states and major metropolitan areas, including New York City. As of Aug. 6, the Environmental Protection Agency labeled air quality throughout the Plains, Midwest and Northeast regions as "unhealthy for sensitive groups," including the city of Chicago.

Washington state is in NOAA's 'view line' for the northern lights tonight
Stargazers in Washington state could get a rare and mesmerizing glimpse of the northern lights today, Aug. 7, and Friday, Aug. 8, according to forecasts by the National Oceanic and Atmospheric Administration Space Weather Prediction Center. New forecast maps show Washington well inside the agency's "view line" for the aurora borealis on both days. NOAA's aurora view line map represents the southernmost areas where the northern lights may be seen on the northern horizon. Cloud conditions across the state are also looking favorable during the darkest portions of the night today. National Weather Service predictions show sky cover percentages of 33% or lower from much of Western and Eastern Washington, including Bellingham, Bremerton, Seattle, Olympia, Vancouver, Spokane, and Walla Walla. Here's more on the northern lights and the best time to see the colorful display in the night sky. What is the best time to see the northern lights in Washington? The best time to view the northern lights in Washington is typically after nightfall from 11 p.m. to 3 a.m., according to AuroraAdmin. The northern lights, viewable on the northern horizon, can last from several minutes to several hours, depending on the severity of solar activity. "The exact duration of the auroras depends on factors such as the intensity of the solar storm, atmospheric conditions, and the strength of the aurora display," the AuroraAdmin website explains. "Keep in mind that while some auroras are brief, others can offer an extended and breathtaking show, adding to the captivating experience of the Washington night sky." Experienced stargazers also know that moving away from city lights and other light pollution increases the chances of getting a good night sky view. The AuroaAdmin website says to be on the lookout for bursts of white light or flickering that looks like clouds. "Especially in areas like Seattle with some light pollution, you are more likely to see predominant greens and reds," the website states. "For a more immersive and vibrant experience, consider capturing long exposures with a camera to reveal the true brilliance of the auroras." Will it be cloudy tonight? Cloud cover predictions from the National Weather Service show mostly clear conditions tonight and into the early morning hours of Friday, Aug. 8. At 2 a.m., the sky cover percentage is forecast to be 29% in Bellingham. It is 33% in Seattle, 15% in Olympia, 3% in the Vancouver area, 7% in Yakima, 24% in Spokane, and 23% in Omak. The weather agency's sky cover map predicts the "expected amount of opaque clouds (in percent) covering the sky valid for the indicated hour." Generally speaking, cloud cover percentages around 30% or lower are considered to be "good" for viewing the night sky, according to What causes the northern lights? The auroras are natural light displays in Earth's sky that are famously best seen in high-latitude regions of the Northern and Southern hemispheres. The phenomenon is caused when electrically charged particles from space enter Earth's atmosphere and collide with molecules and gases like oxygen and nitrogen, causing the atmospheric particles to gain energy. The particles release that energy in the form of light to return to their normal state, according to the University of Alaska at Fairbanks Geophysical Institute website, which tracks the phenomenon. As auroras form, Earth's magnetic field redirects the particles toward the poles through a process that produces a stunning display of rays, spirals, and flickers that have fascinated humans for millennia. Whether hues of green, red, blue, and even pink dance about in the sky depends on the altitude where the collisions occur, as well as the composition and density of the atmosphere at the time.

Feds take steps to fill vacancies at the National Weather Service
Weather Service will hire 450 people, but experts say it won't help fill critical vacancies during current hurricane and wildfire season. The National Weather Service has taken steps to begin filling some of the more than 550 positions left vacant by federal cutbacks and early retirements since Inauguration Day. Earlier in the summer, the agency received an emergency hiring exemption to fill 126 of its vacant positions and has begun to post those jobs on But in an all-hands meeting on Aug. 4, weather service employees learned the agency has since received permission to hire a total of 450 people by September 2026, said two long-time weather service veterans who retired earlier this year. The mass exodus of workers this winter and spring, as the Trump administration aimed to shrink the federal budget and bureaucracy, prompted widespread concern across the weather service staff, many members of Congress and the broader weather forecasting community. Vacancy rates were as high as 40% in some weather service offices, USA TODAY previously reported. Several weather service forecast offices began closing overnight because they could no longer staff the typical 24/7 operations and weather balloon launches to gather critical data were interrupted. While the new hires are "good news," it doesn't mean clear sailing for the beleaguered agency in the months ahead, given the complicated federal hiring process and the need to train new employees, said Brian LaMarre, who retired earlier this year as meteorologist-in-charge of the weather service office in Ruskin/Tampa, Florida, after more than 30 years with the agency. "That still doesn't backfill to what the agency was on January 1, but it's a good step," LaMarre said, noting it will take months to fill posts now vacant and those created by promotions. In an email to USA TODAY, the agency declined to comment, confirm or deny the information that emerged from its employee meeting Aug. 4. In that meeting, employees were told the meteorologist, hydrologist and electronics technician positions have all been exempted from an ongoing federal hiring freeze, said Alan Gerard, another 30-plus year veteran meteorologist who retired earlier this year. Gerard now writes the "Balanced Weather" blog on Substack. In July, President Donald Trump extended that freeze through Oct. 15. Mass job cuts hit NOAA, the agency that oversees hurricane center and weather service The agency also has been given direct hiring authority, a step that typically allows federal agencies slightly more flexibility with the federal hiring rules, Gerard said. Hiring new people to fill critical positions is "good news, but it's not going to help in any concrete way for many months," he said. Considering the time it takes to hire and train new people, these steps "aren't going to help for this hurricane and wildfire season." The weather service isn't just meteorologists So far, the first positions to be advertised are for electronics technician openings, which were among the 126 "critical vacancies." That's especially good news, LaMarre said. The importance of the technicians was overlooked in the initial flurry of reports about the terminations of probationary employees and the consternation over the massive departures at the weather service, he said. The technicians are responsible for maintaining and repairing the all-important radar systems and other equipment used to make forecasts, he said, not only at the weather service forecast offices but also at airports where the weather service has agreements with the Federal Aviation Administration to maintain radar equipment. "These are critical operations pieces," he said. "The publicity is often on the meteorologists, but the technicians are the foundation of what's done." LaMarre said it's also good news that hydrologists will be among those hired. It could allow the agency to follow through on a plan to place hydrologists in state emergency operations centers, to assist in forecasting flood events. They'd already done that in Virigina and were about to do it in Texas, he said.

Here's where the Trump team is scrubbing climate data
In 2024, the United States experienced 27 weather and climate disasters that each topped $1 billion in damages. That's according to a website maintained by NOAA, which maps the costly disasters including heat waves, wildfires and tropical cyclones. Last year was the fourth-costliest on record for U.S. climate and weather disasters, the agency announced Jan. 10. That website won't be updated with this year's data. Advertisement A red banner across the top of the page now states, 'In alignment with evolving priorities, statutory mandates, and staffing changes, NOAA's National Centers for Environmental Information (NCEI) will no longer be updating the Billion Dollar Weather and Climate Disasters product.'
