Early this morning Environment Canada extended the snow squall warning for areas north of Toronto. They say lake effect snow squalls will persist into this afternoon and lots more snow is on the way as the squalls shift towards Dufferin County. Here are the details:
5:31 AM EST Friday 10 November 2017
Snow squall warning in effect for:
- Orangeville – Grand Valley – Southern Dufferin County
- Newmarket – Georgina – Northern York Region
- Innisfil – New Tecumseth – Angus
- Shelburne – Mansfield – Northern Dufferin County
- Midland – Coldwater – Orr Lake
- Saugeen Shores – Kincardine – Southern Bruce County
Snow squalls are expected. Under the snow squall bands, visibilities will be significantly reduced due to the heavy snow combined with blowing snow, and snow will quickly accumulate. Lake effect snow squalls are affecting regions southeast of Georgian Bay and are expected to persist into this afternoon. The heaviest snow squalls are currently located near Collingwood extending inland towards Barrie and Newmarket. Winds will become more northerly this morning, shifting the heaviest snow squalls west of Barrie and Newmarket.
Later this morning these snow squalls are expected to be located from near Meaford east towards Wasaga Beach and extending inland through Dufferin County. Local snowfall amounts of 10 to 15 cm are expected today under the heaviest snow squalls. These are the first significant snow squalls of the season.
Snow squalls cause weather conditions to vary considerably; changes from clear skies to heavy snow within just a few kilometres are common. Prepare for quickly changing and deteriorating travel conditions. Visibility will be suddenly reduced to near zero at times in heavy snow and blowing snow. If visibility is reduced while driving, turn on your lights and maintain a safe following distance. Road closures are possible.
Snow squall warnings are issued when bands of snow form that produce intense accumulating snow or near zero visibilities.
