Watch a wall of dense fog creep across Lake Michigan

Two fishermen on Lake Michigan caught more than a big fish yesterday. On camera, they captured a massive fog bank making its way across the lake. Andrew Ballard and his father Spencer were out for a leisurely day of fishing near Platte Bay, just south of the Sleeping Bear Dunes, when the weather phenomenon came at them.

“The wind was about 20 mph, the waves got bigger and the temperature really dropped. Visibility dropped to about 30 feet, and you lost direction,” Ballard told The Detroit News.

The National Weather Service describes it as advection fog – when warm, moist air moves horizontally over a cold surface.

The Ballards eventually made it back to shore but had to rely on their GPS to get them there.

Here’s a view of the same fog bank taken from Manistee, Michigan.
