Weather Watches, Warnings and Advisories

Tuesday

Snow Squall Warning

  • Barrie – Collingwood – Hillsdale
  • Midland – Coldwater – Orr Lake
  • Orillia – Lagoon City – Washago
  • Grey

Snow squalls developing late this morning.

In the wake of a sharp cold front, lake effect snow will develop, intensifying into stronger snow squalls early this afternoon. The most intense snow squalls are likely late this afternoon and evening.

Local snowfall accumulations of 15 to 20 cm will be possible under the most intense snow squalls by Wednesday morning. Gusty winds will accompany these snow squalls at times resulting in periods of blowing snow.

A short lived break can be expected early Wednesday morning into the afternoon as winds become southwesterly, shifting the snow squalls northward. However, snow squalls will shift back into the region late Wednesday afternoon or early evening as the winds become northwesterly once again. These snow squalls will ease early Thursday morning.

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.

If visibility is reduced while driving, slow down, watch for tail lights ahead and be prepared to stop. Public Safety Canada encourages everyone to make an emergency plan and get an emergency kit with drinking water, food, medicine, a first-aid kit and a flashlight.

Snow Squall Watch

  • Innisfil – New Tecumseth – Angus
  • Bracebridge – Gravenhurst
  • Huntsville – Baysville
  • Port Carling – Port Severn
  • Town of Parry Sound – Rosseau – Killbear Park
  • northern York – northern Durham

Snow Squalls possible today and tonight.

In the wake of a sharp cold front, lake effect snow will develop. Areas to the north are currently under a snow squall warning, however these snow squalls may be strong enough to stretch into the Innisfil and northern York – Durham regions early this afternoon through this evening.

Local snowfall accumulations of 10 to 15 cm will be possible under the most intense snow squalls. Gusty winds will accompany these snow squalls at times resulting in periods of blowing snow.

The snow squalls will shift to the north near midnight as the wind shifts to the southwest.

Snow squalls cause weather conditions to vary considerably; changes from clear skies to heavy snow within just a few kilometres are common. Visibility may be suddenly reduced at times in heavy snow. Public Safety Canada encourages everyone to make an emergency plan and get an emergency kit with drinking water, food, medicine, a first-aid kit and a flashlight.
