On April 4, a Tropical Depression formed just to the East of Milwaukee, Wisconsin. One moved slowly southeast, and shortly after started to curve Northeast. One eventually made landfall near Kalamazoo, Michigan, bringing flooding and minor damage. One crossed through Central Michigan as a remnant low, bringing heavy rains and flooding. the Remnants of TD One dissipated to the Southeast of Traverse, Michigan. One caused a minor $300,000 USD in damage and no deaths. One boat sank as a result of TD One, but nobody died or was injured. Tropical Depressions cannot be retired so TD One was not.

|Peak intensity||95 km/h (60 mph) (1-min) 997 hPa (mbar)|
On June 20, a Tropical Depression formed to the Southeast of Green Bay, Wisconsin.

On September 29, a Tropical Depression formed just to the Northeast of Milwaukee, Wisconsin. Three briefly made landfall in Eastern Wisconsin, but caused no damage or deaths before heading back out into the water. Three eventually became Tropical Storm Doreen and then Cyclone Doreen. Doreen narrowly missed landfall in Michigan and became the first Cyclone of the year to enter Lake Huron.

Doreen eventually made landfall in Canada, causing Catastrophic damage of $3.1 Billion USD in Damage and 37 deaths. Doreen crossed over into lake Ontario and made a 2nd landfall, causing minimal damage before dissipating while north of Montreal. Doreen was so Catastrophic that the name "Doreen" was retired and replaced with the name "Brandee" for the 2028 Great Lakes Cyclone Season.
