Environment Canada has issued a severe thunderstorm watch for Waterloo region and Wellington County, saying wind gusts of up to 100 kilometres per hour are possible Monday morning and afternoon.
“Conditions are favourable for the development of severe thunderstorms that may be capable of producing strong wind gusts, large hail and heavy rain,” the weather agency said in the alert.
In addition to wind, the agency said “torrential downpours” are also possible, which could dump between 25 to 50 millimetres of rain on the region in one hour.
Other things to watch out for in a thunderstorm include:
- Large hail, which can damage property and cause injury.
- Strong wind gusts, which can toss loose objects into the air, damage weak buildings and break branches off trees.
- Lightning, which can be fatal.
According to the agency’s alert, the thunderstorms are occurring across Ontario as a cold front moves through the province from the northwest.
The severe weather is expected to end late Monday, giving way to partly cloudy skies and an overnight low of 13 C.
