Tropical cyclones normally threaten the states during the summer and fall, with their main impact being rainfall. [3] Although Hurricane Agnes was barely a hurricane at landfall in Florida, its major impact was over the Mid-Atlantic region, where Agnes combined with a non-tropical low to produce widespread rains of 6 inches (150 mm) to 12 inches (300 mm) with local amounts up to 19 inches (480 ...
Because of the large range of difficulty that exists beyond Class IV, Class V is an open-ended, multiple-level scale designated by class 5.0, 5.1, 5.2, etc. Each of these levels is an order of magnitude more difficult than the last. That is, going from Class 5.0 to Class 5.1 is a similar order of magnitude as increasing from Class IV to Class 5.0.
In the state of Michigan there are over 11,000 lakes that are 5 acres or larger. With this much water in the state, Michigan is more susceptible to flooding. "Changing the climate is likely to increase the frequency of floods in Michigan. Over the last half century, average annual precipitation in most of the Midwest has increased by 5 to 10 ...

The faster the water flows, the more likely a rapid will form. [3] Rapids are categorized in classes, generally running from I to VI. [2] A Class 5 rapid may be categorized as Class 5.1-5.9. While Class I rapids are easy to navigate and require little maneuvering, Class VI rapids pose threat to life with little or no chance for rescue. [5]
The 2013 Grand Rapids flood lasted from April 12 to 25, 2013, affecting multiple areas in the Grand Rapids metropolitan area. [2] [3] Sudden heavy rainfall, saturation of the ground from rainwater and the flow of tributaries caused the Grand River to rise dramatically, with the river cresting at 21.85 feet (6.66 m) in Grand Rapids on April 21, 2013.

The impact of climate change on water quality is less likely to be beneficial. Warmer temperatures tend to cause more algal blooms, which can be unsightly, harm fish, and degrade water quality. Severe storms also increase the amount of pollutants that run off from the land into the water, further increasing the risk of algal blooms. [2]
