Snow squall watch in effect for:
Sault Ste. Marie – St. Joseph Island
Searchmont – Montreal River Harbour – Batchawana Bay
Cold Arctic air and strong northwesterly winds over the open waters of Lake Superior and Whitefish Bay will result in the development of snow squalls Wednesday morning through Thursday. The heaviest squalls could produce snowfall amounts of 10 to 15 cm per 12 hours along with reduced visibilities in blowing snow.
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. For information on emergency plans and kits go to http://www.getprepared.gc.ca/
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.
