With hot and humid weather in the forecast for Wednesday, Environment Canada has issued a special weather statement for Chatham-Kent and Windsor-Essex.
Environment Canada says daytime temperatures are expected to reach 34 degrees Celsius with humidex values reaching 45 degrees.
Overnight low temperatures on Wednesday night of 23 degrees Celsius will provide minimal relief from the heat.
The weather agency is advising people to drink plenty of water even before they feel thirsty and to spend more time in cool places.
"Check on older family, friends, and neighbours," read the statement. "Make sure they are cool and are drinking water. Never leave people or pets inside a parked vehicle."
Forecasters say a heat warning will not be required, as daytime temperatures will not reach the criteria for a heat warning.
"Heat warnings require hot and humid conditions (temperatures of 31 degrees Celsius or humidex values of 42) to last for two days, including the overnight low in between to be 21 degrees Celsius or higher," read the statement.
