The Missouri Department of Health and Senior Services is hoping that people will heed a warning about heat just a couple days before the official start of summer. Wednesday is Summer Safety Day. At least 19 people died in Missouri as a result of heat-related causes in 2018. That includes five children who were left in hot vehicles. Three of those incidents occurred on the Fourth of July, and included a five-year old girl in Moniteau County, two sisters, ages two years and seven weeks, in Clay County. SEMA, the National Weather Service, and the DHSS encourage everyone to pay attention to forecasts plan accordingly when you’re going to be participating in outdoor activities.
