Lightning in Oscoda County, Michigan

A family was on a tubing outing on the Au Sable River. A thunderstorm rapidly developed, and they attempted to exit the river and find shelter. They were just out of the river, when three individuals were struck by lightning. Two women were pronounced dead at the scene. A man was transported to a hospital in Saginaw in critical condition. He would survive, but require a 10-day hospital stay, and considerable physical therapy after that. The survivor had no recollection of the incident.

Thunderstorms developed over North Central and Northeast Lower Michigan, thanks to a humid and unstable airmass.
