Sunset over D.C. on Tuesday. (ep_jhu via Flickr )

Smoke from dozens of wildfires burning in Canada and Alaska has been filtering into the lower 48 this week, and reached the Mid-Atlantic on Tuesday. There’s a good chance that if you look toward the horizon today, you’ll notice a slight, brown-ish, orange-ish haze, and our sunsets may continue to be enhanced be extra pink thanks to all the particulates.

“Hot spots” on satellite imagery show a large swath of wildfire activity stretching from the Yukon and the Northwest Territories down through Alberta and Saskatchewan covering an area of approximately 400,000 square miles.

NOAA says smoke from the “enormous amount” of wildfires up north has congealed into one massive plume that stretches as far south as the Southeast U.S., and now covers much of the eastern U.S. A deep trough in the jet stream is carrying the smoke across about 3,000 miles, dipping into the south and then turning north up the East Coast.

Sunsets and sunrises have been looking a bit more pink and orange than normal as the particles in the smoke filter the light to favor those colors. Tuesday night’s sunset was enhanced, and we suspect that we’ll see at least one more glowing sunset as the jet stream lifts north over the D.C. area today.
