Alerts in Effect
Severe Thunderstorm WatchIssued at 10:52 Sunday 25 June 2017
Conditions are favourable for the development of strong thunderstorms that are capable of producing significant hail.
Scattered thunderstorms are forecast to develop in regions to the east of Lake Huron and south of Georgian Bay a little later this morning. They will spread eastwards into eastern Ontario this afternoon.
Many of the thunderstorms are expected to produce hail, some of which will likely be 1 to 2 centimetres in size. Given the cool temperatures and favourable atmospheric conditions, the hail may be abundant and nearly cover the ground at times. The main concern is damage to tender crops and plants.
Isolated strong wind gusts to 90 km/h are also possible.
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.
