WEST CARLETON – Environment Canada has issued a spring heat warning, an ominous sign for such an early date in a spring that has already seen very little rain.

“Humidex values reaching 35 are expected for the next three days,” Environment Canada released in a statement this afternoon (May 25). “The first heat event of the season is expected to run from Tuesday through Thursday.”

High daytime temperatures in the low thirties are expected Tuesday afternoon and temperatures are forecast to be similar Wednesday and Thursday. Humidex values in the mid to upper thirties are also expected.

Showers and cooler temperatures are expected late Thursday or Thursday night.

“Extreme heat affects everyone,” Environment Canada said. “The risks are greater for young children, pregnant women, older adults, people with chronic illnesses and people working or exercising outdoors.”

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.
