AREAS OF DENSE FOG ACROSS THE EASTERN HALF OF THE UPPER PENINSULA EARLY THIS MORNING... Webcams, surface observations, and satellite imagery show that areas of dense fog have developed over portions of Delta, Alger, and Schoolcraft counties. Expect the dense fog to spread into Luce County too later this morning. Therefore, if you hit an area of dense fog, be sure to slow down and use your low-beam headlights. The fog should erode away right after sunrise.
