Wildfire Smoke and Hot

Created by the NWS Missoula WFO

Dry conditions are expected to persist across the Northern Rockies for the foreseeable future. With deep southwesterly flow transporting smoke from active fires in Washington and Oregon, air quality will likely remain poor, and it may get worse before it gets better. We remain locked into a synoptic setup featuring elevated fire weather conditions. Specifically hot, dry, and breezy weather. This pattern continues to stream smoke into the region, degrading air quality and reducing visibility. - Stay cool and limit outdoor exposure when smoke is thickest. - Check in on vulnerable neighbors, friends, and family, especially those without air conditioning or with respiratory ailments. - Always check the back seat for pets or children.

A split-screen graphic. The left side has a tan background with rust-colored boxes containing white text that reads "Hot & Smoky Northern Rockies - for the foreseeable future". It lists impacts: "Degraded Air Quality - Most susceptible: young, elderly, those with respiratory ailments," "Decreased Visibility - Aviation, Periodic impacts to road travel," and "Hot Weather Reminders: Always check the back seat, and never leave pets or children in cars. Drink plenty of fluids, avoid strenuous activity during the hottest part of the day." The right side shows a satellite image of the Western US with white arrows pointing to thick smoke plumes moving into the region, labeled "Increasingly active wildfires in Oregon and Washington". The NWS Missoula logo and text are at the bottom.
