Four day heat warning in effect for Mississauga, Brampton, and Halton
Published September 3, 2023 at 12:20 pm
A heat event is expected today (Sept. 3) in Mississauga, Brampton and Halton with a possibility of extending into Wednesday.
According to Environment Canada, over the next 3 to 5 days the humidex values are anticipated to reach 34, posing potential health risks to residents.
“A hot airmass is expected to affect the area beginning today and persisting through at least mid-week,” the statement read.
Daytime temperatures for today will hover around 29 to 32 degrees Celsius, with expectations of rising to approximately 31 to 35 degrees Celsius as the week progresses.
Although the temperatures will be in the high thirties, the Weather Network predicts it will feel somewhere between 41 and 43 degrees Celsius with hottest days being Tuesday and Wednesday.
In certain rural areas, overnight temperatures might dip just below alert thresholds.
Environment Canada mentions that the combination of high humidex values and daytime highs is notably unusual for early September.
Additionally, the hot and humid conditions may lead to deteriorating air quality, potentially pushing the Air Quality Health Index into the high-risk category.
The elevated heat poses greater risks especially for young children, pregnant women, older adults, individuals with chronic illnesses, and those engaged in outdoor work or exercise.
Residents are advised to look out for signs of heat-related illnesses, such as swelling, rashes, cramps, fainting, heat exhaustion, heat stroke, and exacerbation of pre-existing health conditions.
Environment Canada included some helpful tips on how residents can beat the heat:
- Drink plenty of water even before you feel thirsty and stay in a cool place.
- Check on older family, friends and neighbours. Make sure they are cool and drinking water.
- Never leave people or pets inside a parked vehicle.
- Outdoor workers should take regularly scheduled breaks in a cool place.
The arrival of a cold front later this week is expected to bring relief from the ongoing heat, although the exact timing remains uncertain.insauga's Editorial Standards and Policies advertising
