8:25 AM EDT Thursday 13 July 2017
Severe thunderstorm warning in effect for:
- Niagara Falls – Welland – Southern Niagara Region
- St. Catharines – Grimsby – Northern Niagara Region
At 8:25 a.m. EDT, Environment Canada meteorologists are tracking an area of severe thunderstorms capable of producing strong wind gusts, up to nickel size hail and heavy rain.
Thunderstorms from Sarnia to Woodstock will continue over the next few hours and are moving southeastward to Hamilton and Niagara. Heavy rain with near 50 millimetres in an hour and wind gusts to 90 kilometres per hour are the main threats. Total rainfall amounts in excess of 50 millimetres are possible this morning in localized areas.
Take cover immediately, if threatening weather approaches. Heavy downpours are likely to cause flash floods and water pooling on roads. Fast-moving water across a road can sweep a vehicle away. Avoid driving through water on roads. Watch for possible washouts near rivers, creeks and culverts.
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 using #ONStorm.
