People and businesses are urged to avoid activities which lead to ozone formation. These activities include refueling vehicles or topping off when refueling, using gasoline-powered lawn equipment, and using charcoal lighter fluid. It is recommended that active children and adults, and persons with respiratory diseases such as asthma, limit prolonged outdoor exertion.
The National Weather Service’s excessive heat warning also continues today and remains in effect until 8 p.m. Friday.
Heat index values will top 100 again in many locations, with the highest values southeast of Grand Rapids. Temperatures are expected to remain around 90 through the weekend, except only into the mid 80s along the Lakeshore, with humidity levels remaining high.
Those prone to heat stress will need take frequent breaks, especially when shade or air conditioning is not available. Strenuous outdoor activity may lead to heat injuries such as heat stroke, heat exhaustion or heat cramps.
Take extra precautions if you work or spend time outside. When possible, reschedule strenuous activities to early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke, wear lightweight and loose-fitting clothing when possible, and drink plenty of water.
Local governments remind residents that there are options available for people to keep cool during the heat. This includes Grand Haven, where officials said their public buildings are open during business hours; and the Village of Spring Lake, which is offering Barber School from 8 a.m. to 5 p.m. The Salvation Army, 310 N. Despelder St. in Grand Haven, is also open as a cooling center from 9 a.m. to 4 p.m.
