Another day, another heat warning in Windsor-Essex.
Although areas near the lakes could be slightly cooler than regions further inland, hot and humid air continues to bring deteriorating air quality and can result in the Air Quality Health Index approaching the high risk category.
Residents are reminded to watch for the effects of heat illness including swelling, rash, cramps, fainting, heat exhaustion, heat stroke and the worsening of some health conditions.
Drink plenty of water even before you feel thirsty and stay in a cool place.
