Just as summer wanes, we are now under a heat warning from Environment Canada.
Unlike in previous years, this warning is expected to last about a day.
It will be hot and humid Tuesday, but a cooler air mass is expected to move in shortly thereafter.
Here’s the latest from Environment Canada:
Heat Warning in effect for:
- Chatham-Kent – Rondeau Park
- Windsor – Leamington – Essex County
A hot and humid airmass is expected to affect portions of southwestern Ontario and the Golden Horseshoe on Tuesday. Humidex values near 40 are forecast for Tuesday afternoon. A cold front will sweep across the area Tuesday night bringing a return to near seasonal temperature values for the remainder of the week.
While extreme heat can put everyone at risk from heat illnesses, health risks are greatest for
– older adults
– infants and young children
– people with chronic illnesses such as breathing difficulties, heart conditions or psychiatric illnesses
– people who work in the heat
– people who exercise in the heat
– people without access to air conditioning and
– homeless people.
Drink plenty of liquids especially water before you feel thirsty to decrease your risk of dehydration. Thirst is not a good indicator of dehydration.
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.
Environment Canada meteorologists will update alerts as required, so stay tuned to your local media or Weatheradio. Email reports of severe weather to firstname.lastname@example.org or tweet with the hashtag #ONStorm.
