Severe thunderstorm watch in effect for:
- Niagara Falls – Welland – Southern Niagara Region
- St. Catharines – Grimsby – Northern Niagara Region
Conditions are favourable for the development of severe thunderstorms that may be capable of producing strong wind gusts and heavy rain.
Slow moving thunderstorms in the area have the potential of producing locally heavy downpours.
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 firstname.lastname@example.org or tweet reports to #ONStorm.
