Alerts for: Dufferin - Innisfil


9:09 PM EST Sunday 19 November 2017
Snow squall warning in effect for:

  • Shelburne - Mansfield - Northern Dufferin County

An intense snow squall band is developing off of Lake Huron this evening and is expected to slowly shift northward tonight. Snowfall rates of a few centimetres per hour are likely under this band.

Local snowfall amounts of 10 to 20 centimetres are likely tonight.

The snow squall activity is expected to end later Monday morning.

Snow squalls cause weather conditions to vary considerably; changes from clear skies to heavy snow within just a few kilometres are common. Visibility will be suddenly reduced to near zero at times in heavy snow and blowing snow. Travel is expected to be hazardous due to reduced visibility.

Snow squall warnings are issued when bands of snow form that produce intense accumulating snow or near zero visibilities.

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to or tweet reports using #ONStorm.
