A strong mid-latitude cyclone intensified over the Lake Superior region on 24 September 2010. This storm produced wind gusts as high as 42 knots (48 mph), which caused some tree damage and some minor coastal flooding in parts of the Upper Peninsula of Michigan.

AWIPS images of 4-km resolution GOES-13 6.5 µm water vapor channel data (above) showed the evolution of the cyclone as it intensified during the day.
