At 7:43 p.m. EDT, Environment Canada meteorologists are tracking a line of severe thunderstorms capable of producing very strong wind gusts, up to nickel size hail and heavy rain.

Doppler radar indicates a broad line of thunderstorms from near Stratford to Windsor moving southeastward at 70 km/h. These thunderstorms are producing intense lightning and are capable of producing wind gusts up to 90 km/h.

Strong wind gusts can toss loose objects, damage weak buildings, break branches off trees and overturn large vehicles. Lightning kills and injures Canadians every year. Remember, when thunder roars, go indoors!

Severe thunderstorm warnings are issued when imminent or occurring thunderstorms are likely to produce or are producing 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.

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