Severe Thunderstorm Watch Issued

8

With the heat and humidity now in place, so are the ingredients for thunderstorms. Hot conditions are expected to last through much of the upcoming weekend and all next week. Some storms in these conditions can grow to severe levels. This will be the pattern for the next 48 to 72 hours.

8:50 PM EDT Friday 29 June 2018
Severe thunderstorm watch in effect for:

Agawa – Lake Superior Park
Sault Ste. Marie – St. Joseph Island
Searchmont – Montreal River Harbour – Batchawana Bay
Areas of thunderstorms over and just east of Lake Superior will track slowly east and southeastward across portions of the regions this evening and overnight.

Some of these storms will be capable of producing damaging wind gusts of 90 to 100 km/h, large hail, torrential downpours and frequent lightning.

Strong wind gusts can toss loose objects, damage weak buildings, break branches off trees and overturn large vehicles. Remember, severe thunderstorms can produce tornadoes. Heavy downpours can cause flash floods and water pooling on roads. 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.
