Timelapse shows desne fog rolling across Albany, N.Y.

On Thursday morning, September 5, timelapse footage from the NYS Mesonet at the University of Albany captured fog rolling through Albany, New York.

The fog blanketed the campus before dissipating a few hours later. Local authorities warned motorists of "locally dense" fog. It's no surprise to see fog across Upstate New York. Fall is the Northeast's foggiest season for interior locations.

Fog forms when the air cools, and moisture condenses into tiny water droplets near the ground. One of the foggiest places in the U.S. is Cape Disappointment, near Ilwaco, Washington, which experiences over 100 foggy days annually.
