‘Dangerous’ Thunderstorms Possible

Watches

ISSUED AT: 10:52 AM EDT Tuesday 16 August 2016
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 dangerous thunderstorms that may be capable of producing damaging wind gusts and torrential rain.

Risk of localized damaging winds from thunderstorms.

Scattered thunderstorms are expected to develop over portions of the regions today. Some of these storms will have the potential to become severe with damaging winds and torrential downpours.

There will also be the risk for an isolated tornado.

The threat for storms will end over southwestern Ontario by mid afternoon, over the Golden Horseshoe late this afternoon, and over eastern areas early this evening.

Very strong wind gusts can damage buildings, down trees and blow large vehicles off the road. 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 storm.ontario@ec.gc.ca or tweet reports to #ONStorm.
