Heat Warning in effect for:
Goderich - Bluewater - Southern Huron County
Listowel - Milverton - Northern Perth County
Stratford - Mitchell - Southern Perth County
Wingham - Blyth - Northern Huron County
First heat event of the season continues this week.
Temperatures will peak again to near the thirty degree mark in many areas today. While temperatures Thursday will continue to be above normal, they will be a little lower than today due to more cloud cover and perhaps an isolated shower or thunderstorm in the afternoon.
Humidex values in the mid to upper thirties will prevail again this afternoon.
A cold front will deliver considerably cooler and less humid air to Southern Ontario on Friday.
Extreme heat affects everyone.
The risks are greater for young children, pregnant women, older adults, people with chronic illnesses and people working or exercising outdoors.
Drink plenty of water even before you feel thirsty and stay in a cool place.
Never leave people or pets inside a parked vehicle.
Heat warnings are issued when very high temperature or humidity conditions are expected to pose an elevated risk of heat illnesses, such as heat stroke or heat exhaustion.
