Hot, sticky tropical air means a threat of thunderstorm development later today. A very warm tropical air mass has pushed into the area from the gulf states bringing with it a lot of humidity. Environment Canada has not issued a heat warming for this area however we are in the watch box for severe thunderstorms until Monday morning.

1:07 PM EDT Sunday 05 August 2018

Severe thunderstorm watch in effect for:

Sault Ste. Marie – St. Joseph Island

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

Thunderstorms are expected to move into the region from Michigan later this afternoon, mainly after 3 PM EDT. These thunderstorms will have the potential to produce damaging wind gusts as well as large hail.

The threat of severe weather will diminish early 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. 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.
