Coming Our Way: Thunderstorms, Wind Gusts, Downpours

Watches

10:35 AM EDT Sunday 18 June 2017
Severe thunderstorm watch in effect for:

  • Niagara Falls – Welland – Southern Niagara Region
  • St. Catharines – Grimsby – Northern Niagara Region

Numerous thunderstorms are expected to affect much of southern Ontario this afternoon and early evening. Damaging wind gusts and torrential downpours giving rainfall amounts in excess of 50 mm are the main threats.

Large hail can damage property and cause injury. Strong wind gusts can toss loose objects, damage weak buildings, break branches off trees and overturn large vehicles. 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.

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to ec.cpio-tempetes-ospc-storms.ec@canada.ca or tweet reports using #ONStorm.
