Grand Rapids, Michigan, is facing a combination of high humidity and ozone pollution this Saturday, creating hazardous air conditions as temperatures climb into the 90s. The combination of high heat and poor air quality can make outdoor activities unsafe, especially for those with respiratory issues.
Air Quality Advisory and Health Risks
The Michigan Department of Environment, Great Lakes, and Energy (EGLE) has issued an Air Quality Advisory for several western Michigan counties, including Kent, Ottawa, Muskegon, Allegan, and Van Buren. The advisory warns that ground-level ozone could reach levels that are unhealthy for sensitive groups, such as individuals with asthma or other respiratory conditions. Residents are advised to limit outdoor activities and avoid activities like refueling vehicles or using gas-powered lawn equipment until the air quality improves.
Hot Weather and Thunderstorm Risk
The National Weather Service in Grand Rapids is forecasting temperatures to reach the low to mid-90s on Saturday, with a heat index nearing 95°F. A 30% chance of thunderstorms is possible by the afternoon, particularly east of U.S. 131. While the storms are expected to be scattered, lightning could still pose a significant risk, so outdoor activities should be closely monitored.
