Delta crews in the Detroit Metropolitan Wayne County Airport and others across the Great Lakes Region are working diligently to keep flights operating safely during the ongoing winter storm. Runway treatment and other safety precautions have been a difficult but key process in this ongoing operational effort.

Snowfall has lightened in the Chicago area, and DTW is currently under diversion alert for the time being, although the moderate to heavy snow is forecasted to diminish at approximately 5 p.m. ET with light snow predicted for the remainder of the night.

A winter weather waiver has been issued for affected cities including Chicago-Midway, Chicago-O'Hare, Cleveland, Detroit and Milwaukee to allow customers to make a one-time change to their travel plans without incurring a fee.
