Residents are warned of two weather advisories impacting southern Ontario today (July 14).
Environment Canada meteorologists are tracking a severe thunderstorm near Osborne Corners that can produce strong wind gusts. The storm is moving east at 40 km/h and poses hazards, including 90 km/h wind gusts and the potential for a tornado.
The following areas are affected:
- Mississauga
- Brampton
- Halton

- Paris
- St. George

Strong wind gusts can toss loose objects, damage weak buildings, break tree branches, and overturn large vehicles.
Severe thunderstorms can also produce tornadoes.
“Take cover immediately if threatening weather approaches. Lightning poses a significant risk, so remember, when thunder roars, go indoors,” Environment Canada notes on its website.
A second advisory has been issued. A hot and humid airmass is expected to bring heat and humidity to southern Ontario beginning today and possibly continuing into Tuesday.
Daytime temperatures will hit 30 C, with humidex values near 40, providing little relief at night as temperatures will remain around 20 C.
This can lead to deteriorating air quality, with the Air Quality Health Index approaching high-risk levels. A cooler airmass is anticipated to arrive Tuesday night.

Environment Canada says extreme heat can affect everyone’s health.
Individuals are urged to drink plenty of water regularly to avoid dehydration, even before they feel thirsty.
Wearing a wide-brimmed, breathable hat or umbrella is also encouraged to limit direct sun exposure.
Never leave people, especially children or pets, inside a parked vehicle. Consult a health professional about how medications or health conditions can increase heat risk. Opt for cool, light meals and avoid using the oven.
