Conditions are favourable for the development of dangerous thunderstorms that may be capable of producing damaging wind gusts and damaging hail.

Scattered thunderstorms are expected to move eastward across portions of the regions later this afternoon and this evening.

Very large hail can damage property, break windows, dent vehicles and cause serious injury. Very strong wind gusts can damage buildings, down trees and blow large vehicles off the road. Remember, severe thunderstorms can produce tornadoes. Lightning kills and injures Canadians every year. Remember, when thunder roars, go indoors!

Severe thunderstorm watches are issued when atmospheric conditions are favourable for the development of thunderstorms that could produce one or more of the following: large hail, damaging winds, torrential rainfall.

The Office of the Fire Marshal and Emergency Management recommends that you take cover immediately if threatening weather approaches.

A heat event continues for the Canada Day long weekend.

A hot and humid airmass is currently in place across the area. Daytime high temperatures in the low thirties are expected again today, with humidex values in the mid to high thirties. Low temperatures overnight are expected to be in the high teens to low twenties providing little relief from the heat.

Hot temperatures are expected to persist through most of the week.

Extreme heat affects everyone.

The risks are greater for young children, pregnant women, older adults, people with chronic illnesses and people working or exercising outdoors.

Watch for the effects of heat illness: swelling, rash, cramps, fainting, heat exhaustion, heat stroke and the worsening of some health conditions.

Never leave people or pets inside a parked vehicle.

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to or tweet reports using #ONStorm.
