On Wednesday June 10 at 12:30 p.m. Environment Canada issued a severe thunderstorm watch for:

  • Bracebridge - Gravenhurst

  • Huntsville - Baysville

  • Port Carling - Port Severn

  • Town of Parry Sound - Rosseau - Killbear Park

Conditions are favourable for the development of dangerous thunderstorms that may be capable of producing damaging wind gusts, large hail and heavy rain. Isolated severe thunderstorms may develop this afternoon into this evening. The main threats are wind gusts of 100 km/h which may cause local power outages and torrential downpours. Large hail is possible. Very strong wind gusts can damage buildings, down trees and blow large vehicles off the road. Remember, severe thunderstorms can produce tornadoes. Heavy downpours are likely to 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. Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to or tweet reports using #ONStorm.
