15cm Likely Overnight

0

A low pressure system will cross the region tonight, accompanied by a period of snow. As northwest winds pick up behind the low, a few snow squalls are expected to develop over eastern Lake Superior and affect some areas to the east of the lake. 10 to locally 15 cm of fresh snow is likely tonight as well as Thursday before they shift south of the district later in the day.

Snow squall warning in effect for:

Sault Ste. Marie – St. Joseph Island

Snow squalls cause weather conditions to vary considerably, changes from clear skies to heavy snow within just a few kilometres are common. Be prepared to adjust your driving with changing road conditions. Consider postponing non-essential travel until conditions improve. 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. For information on emergency plans and kits go to http://www.getprepared.gc.ca/

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

Environment Canada meteorologists will update alerts as required, so stay tuned to your local media or Weatheradio. Email reports of severe weather to storm.ontario@ec.gc.ca or tweet with the hashtag #ONStorm.
