The National Weather Service has issued a heat advisory and hazardous weather alert for Macomb County, while the Michigan Department of Natural Resources and Environment has issued an air quality alert.
Increasing heat and humidity will lead to temperatures in the upper 90s today and Wednesday, according to the NWS. Temperatures are expected to remain high overnight and a second day spent in the 90s will provide a "dangerous heat stress index," according to the NWS.
The heat advisory will remain in effect until midnight Wednesday.
The NWS recommends the following:
- Stay in an air-conditioned room when possible.
- Stay out of the sun whenever possible.
- Check on relatives and neighbors, especially the elderly.
- Do not leave children or pets unattended in vehicles.
In addition to the high temperatures, isolated thunderstorms have led the NWS to issue a hazardous weather alert for Macomb County.
As the atmosphere becomes increasingly hot and unstable, isolated thunderstorms could be seen Tuesday night, according to the NWS. While severe weather is not expected, any thunderstorm that does develop is capable of producing wind gusts up to 45 mph, small hail and brief heavy rainfall.
From Wednesday through Monday, scattered showers and thunderstorms could return and strong or severe thunderstorms could strike late Wednesday into Thursday, according to the NWS.
Due to the air quality alert, the DNRE is uring people and business to avoid activities which lead to ozone formation, such as refueling vehicles or topping off when refueling, using gas-powered lawn equipment and charcoal lighter fluid.
The DNRE encourages car pooling, biking to work, delaying or combining errands and using water-based paints.
Strenuous outdoor activity should be limited and persons with respiratory diseases such as asthma should remain indoors whenever possible.
