Snow Squall Watch In Effect


Snow squall watch in effect for:

  • Sault Ste. Marie – St. Joseph Island

Brisk southwest winds blowing over the open waters of Lake Huron and Lake Michigan are expected to generate flurries and possible snow squalls this evening and overnight. The most intense activity is expected to remain south of the cities of Sudbury and Sault Ste Marie.

The heaviest snow squalls may produce snowfall amounts of 10 to 15 cm per 12 hours alsong with reduced visibilities.

Snow squalls cause weather conditions to vary considerably, changes from clear skies to heavy snow within just a few kilometres are common. Travel may be hazardous due to sudden changes in the weather. 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.

Snow Squall Watches are issued when conditions are favourable for the formation of bands of snow that could produce intense accumulating snow or near zero visibilities.
