A severe thunderstorm watch has been issued for Niagara.
Environment Canada saying that conditions are favourable for the development of severe thunderstorms that may be capable of producing strong wind gusts and heavy rain.
Thunderstorms are expected to develop this afternoon and could persist into the overnight hours.
These thunderstorms will be capable of producing wind gusts of 90 km/h and locally heavy rainfall.
While 30 mm of rain is in the forecast, total rainfall amounts near 50 mm are possible in areas where multiple thunderstorms occur.
EC officials saying that severe thunderstorms can produce tornadoes and heavy downpours can cause flash floods and water pooling on roads.
They are reminding residents that lightning kills and injures Canadians every year. Remember, when thunder roars, go indoors!
