Overview

Numerous thunderstorms developed across southern Lower Michigan during the evening of May 7, 2024. Many thunderstorm cells exhibited some rotation, and a couple of strongly rotating storms produced tornadoes during parts of their life cycle. One of the tornadoes cut a path across the city of Portage and in portions of adjacent townships in Kalamazoo County. Large hail also fell from some of the storms in southern Michigan, in some cases up to 4 inches in diameter. Information about the Portage tornado is below. Information about other tornadoes in southern Michigan is available from NWS Northern Indiana. |
