Monsoonal moisture will bring a flash flooding threat to the Desert Southwest. Sweltering heat persists from the Plains to the southern Mid-Atlantic through tonight. Read More >

Overview

A line of severe thunderstorms moved through Western Lower Michigan during the early morning hours of June 25, 2024. Extensive wind damage occurred along the Lake Michigan lakeshore, starting near Pentwater and Silver Lake in Oceana County, and spreading south-southeast through Muskegon County, where Whitehall and Muskegon were particularly hard-hit by winds measured between 60 and 70 mph, estimated in some spots to be over 80 mph. Some hail ranging from dime to quarter size was reported as well, but the main impacts came from wind damage to trees and powerlines that then resulted in power outages affecting many thousands.

After storms passed, winds remained strong and erratic in direction thanks to a "wake low" phenomenon that occurred behind (or in the wake of) the exiting storms. Large and rapid pressure changes associated with the wake low produced fluctuations in the height of water levels along the southeastern and southern Lake Michigan shoreline.
