The CDC/NWS HeatRisk Experimental Tool is forecasting a multiple day heat event starting Monday, June 17 and potentially going through Friday, June 21. The forecast is updated regularly.
All counties are forecasted to experience some level of heat risk ranging from Minor (Yellow) to Extreme (Magenta). Forecasted areas most at risk:
- Monday June 17: Major heat risk level (red) for the majority of the Lower Peninsula.
- Tuesday June 18: Extreme heat risk level (magenta) for following counties: Antrim, Allegan, Barry, Berrien, Branch, Cass, Calhoun, Clare, Clinton, Genesee, Grand Traverse, Gratiot, Hillsdale, Ionia, Ingham, Isabella, Kalamazoo, Kent, Mecosta, Midland, Montcalm, Ottawa, Osceola, Saginaw, Saint Joseph, and Van Buren. Check the HeatRisk map for updates. Major heat risk level (red) for most of the remaining Lower Peninsula. Moderate heat risk level (orange) for the Upper Peninsula, western and northeastern areas.
- Wednesday June 19: Extreme level heat risk (magenta) for most of the southern half of the Lower Peninsula. Major level heat risk (red) for the majority of the remaining Lower Peninsula south of Otsego County.
Major (red) and extreme (magenta) levels of heat affects anyone without effective cooling and/or adequate hydration. Impacts likely in some health systems, heat-sensitive industries and infrastructure. Moderate (orange) level of heat affects most individuals sensitive to heat, especially those without effective cooling and/or adequate hydration. Most sensitive groups include: pregnant people, older people, children, people with chronic conditions (ex. cardiovascular disease, respiratory illness such as asthma, diabetes), those on certain medications (ex. diuretics, some antipsychotics, some antidepressants, some antihypertensive agents), people who live alone, and those who may be more exposed to heat including: outdoor workers, low-income individuals, unhoused individuals, individuals without air conditioning, and individuals who exercise outside.
Tips:
- Watch out for heat illness symptoms in yourself, co-workers, and neighbors during hot weather. Symptoms of heat-related illness vary, but may include: heavy sweating, muscle cramps, weakness, confusion, disorientation, slurred speech, dizziness, headache, nausea, vomiting, fainting, tiredness, and high body temperature.
- Fans are effective only if indoor temperatures are less than 90°F. With indoor temperatures above 90°F, a fan can increase body temperature.
