With more hot, humid weather blanketing the region for the next couple of days, the Chatham-Kent Public Health Unit has issued another heat warning. 
Officials say people should do what they can to keep cool, and keep an eye on vulnerable friends, family, or neighbours.
Heat-related illness can affect the elderly, very young, people with chronic illnesses, and even healthy people if they take part in strenuous activities and don’t take precautions.
A heat warning is issued when three or more consecutive days are forecast to have a daytime high temperature of 31°C or more or a Humidex greater than 42°C.
