Dense Fog Drops Visibility to Near Zero in Michigan’s Upper Peninsula and Flint for a Fourth Straight Morning as Saginaw Stays Socked In
FLINT, MI — Michigan is waking up under a thick blanket of dense fog for the fourth straight morning on Friday, October 23, as calm winds and high surface humidity continue to create ideal conditions for fog formation across the state. Visibility is expected to fall under one mile and even below half a mile in many inland areas, with some locations seeing no visibility at times. The fog forecast is valid from 12:00 AM to 9:30 AM EDT, and the densest fog is expected across the Upper Peninsula.
Upper Peninsula Faces the Worst Conditions
The most dense fog is focused across the central and eastern Upper Peninsula, where visibility may drop to none at times. This zone includes areas near Grand Marais, Naubinway, and the interior of the eastern U.P., stretching toward the Mackinac region.
Surrounding areas, including Marquette, Iron River, Escanaba, and Sault Ste. Marie, are expected to see visibility under half a mile. Farther west, Houghton falls into the under 2 miles zone, while Ironwood remains generally clear.
Northern Lower Michigan Under Thick Fog
Much of Northern Lower Michigan will also see dense fog with visibility under half a mile. Communities such as Cheboygan, Gaylord, Cadillac, West Branch, and Mt. Pleasant are within this zone.
Areas near the Lake Michigan shoreline, including Traverse City and Ludington, fall into the under 2 miles category, while Alpena and Oscoda along Lake Huron may see visibility under 2 miles as well.
Flint Area Could See Near Zero Visibility
In Mid-Michigan, a pocket of near zero visibility is expected near Flint, where fog could be extremely dense at times. Surrounding areas, including Saginaw, Lansing, Jackson, Pontiac, and Adrian, are expected to see visibility under half a mile.
The Thumb region, including Sandusky, also falls into the under half a mile category, while Port Austin and St. Clair may see visibility under 2 miles.
Southwest Michigan Mostly Clear
Southwest Michigan will be the least affected part of the state. Areas near Muskegon, Holland, Kalamazoo, and Niles are expected to remain generally clear. Grand Rapids and Coldwater may see some patchy fog, with visibility under 2 miles at times.
Detroit is expected to see visibility under 2 miles, with an area of none at times possible farther southeast near the metro region.
Fog May Drift In and Out Quickly
The fog will not stay in one place throughout the night. Instead, it may drift around over the overnight hours, meaning some areas could be clear for a time before fog rolls in suddenly. Drivers should be prepared for rapid changes in visibility.
Driving Safety in Dense Fog
Drivers are urged to slow down, use low-beam headlights, and leave extra distance between vehicles. High beams should be avoided, as they reflect off fog and reduce visibility further. Morning commuters should allow extra travel time until the fog lifts after sunrise.
