August 19, 2013 - Have you wondered why it has been looking quite hazy outside the past few days? This is due to smoke from large wildfires that continue to burn over Idaho, northwestern Wyoming, western Montana, southern Washington, Oregon, and northern California. The largest of these fires in Idaho has reached over 100,000 acres in size. Westerly upper level winds continue to transport the smoke over northeast Wyoming into western South Dakota. The image below is a satellite derived fire and smoke analysis from the morning of Monday, August 19. The red dots represent active fires, the lavender color represents dense smoke, the yellow colors represent moderately dense smoke, and the green colors are thin smoke.
