PORTLAND, Ore. (KOIN) — Flood advisories, watches and warnings are in effect for a large portion of the state, especially the Willamette Valley, as thunderstorms roll through. But the unhealthy air will continue to linger in the area through at least the middle of Saturday.
There is a possibility of thunderstorms throughout Friday which would trigger flash floods in the areas severely burned by the wildfires. There will be heavy rains at times but lessening later Friday and into Saturday, which would have some scattered light showers.
Major concerns for flash flooding are still out across the Cascade foothills due to heavy rain in the thunderstorms. A Flash Flood Watch in place until 9 p.m.
This area has not seen rain in almost a month. This system will help clear out the smoke and will improve the air quality. As of Friday morning, the air in the Portland metro had improved to the “unhealthy” level.
But the Air Quality Alert was extended for most parts of Oregon until 6 p.m. Saturday.
Air quality has greatly improved and will continue to do so for the coast and valley. Areas east of Eugene and Salem, as well as central and Eastern Oregon will continue with patchy and dense smoke through the weekend due to proximity to the wildfires.
