Wildfire smoke is expected to blanket large parts of the U.S. again this week, with the Pacific Northwest being the most affected region. The National Weather Service has issued forecasts indicating that smoke from dozens of fires currently burning in the area will spread across the northern U.S. and reach parts of the South.

The situation is expected to worsen as wind patterns carry the smoke further south. Officials warn that air quality could deteriorate significantly, posing health risks to residents, especially those with respiratory conditions. The fires, which have been ongoing in the Pacific Northwest, continue to burn under dry conditions, making containment difficult.

Authorities are urging people to limit outdoor activities and monitor air quality updates. While the exact impact varies by location, the forecast suggests that multiple states will experience reduced visibility and unhealthy air conditions. (ca.news.yahoo.com)
