Humidex may reach 40 Thursday and Friday: Environment Canada

Deteriorating air quality may also cause the Air Quality Health Index to move closer to the high-risk category

Environment Canada has issued a heat warning for most of southern Ontario, including our region. Humidex values ​​are expected to reach the 40s in many areas on Thursday and Friday. Deteriorating air quality is also a possibility, which could lead to the Air Quality Health Index approaching the high-risk category.

Below is the full version of the Environment Canada alert:

Heat warning issued by:
• Newmarket – Georgina – Northern York Region
• Vaughan – Richmond Hill – Markham
• Orillia – Lagoon City – Washago

Current Details:
Warm and humid conditions are expected Wednesday through Friday.

Temperatures on Wednesday are expected to reach 30 degrees Celsius. Thursday, while slightly cooler, will be very humid with humidex values ​​in the upper 30s. Friday is expected to be very warm with humidex values ​​reaching the 40s in many areas. Low temperatures in the low 20s will provide little relief from the heat. Expect cold weather on Saturday.

Areas near lakes can be expected to remain cooler than inland areas.

Hot and humid air can worsen air quality and approach the high-risk category of the Air Quality Health Index.

Watch out for the effects of heat illness: swelling, rashes, cramps, fainting, heat exhaustion, heat stroke, and worsening of certain health conditions.

Drink plenty of water before you feel thirsty and stay in a cool place.

Check with older family members, friends, and neighbors. Make sure they are cool and drinkable

Never leave people or pets inside a parked vehicle.

Outdoor workers should take regularly scheduled breaks in a cool place.
