Not only is this Washington State summer abnormally dry, it's also bringing extended fire-smoke visits back to Seattle.

Today's "smoke veil" comes from Canada, specifically the hundreds of wildfires that are currently burning in British Columbia. (If you think it's bad here, check out Vancouver, BC.) So when is the smoke leaving?

According to the Washington Smoke Information blog, "westerly winds should return on Wednesday" and blow the fire smoke back out of here.

Meanwhile, on the other side of the mountains, according to the blog, "residents in the northern parts of Central and Eastern Washington are experiencing severe smoky conditions due to both local and regional wildfires that are currently burning. Monitors are showing Unhealthy to Very Unhealthy air quality from Wenatchee to Spokane, with no clearing expected in the near-term forecast."

Wildfires, a scientist told The Atlantic last year, are a "canary in the coal mine" when it comes to effects from climate change. That same scientist helped draft a paper, published in the Proceedings of the National Academy of Sciences two years ago, which found that over the last three decades, wildfires in the US have burned double the area they would have absent climate change.
