Environment Canada has issued a snow squall watch for Kingston, Odessa, Frontenac Islands, Napanee, Consecon, Picton, and Sandbanks Park, saying that snow squalls from Lake Ontario are possible on Monday, with total snowfall amounts up to 20 cm, particularly near the Lake Ontario shoreline.
Environment Canada says the expected snow squalls will begin over the Picton area Monday morning and spread slowly north, reaching Kingston and the St. Lawrence River in the afternoon, then tapering to flurries Monday night.
“Snow squall development is expected over Lake Ontario starting early Monday morning. These snow squalls will slowly move north through the day Monday. These snow squall may reach highway 401 Monday afternoon, however, it is possible that the snow squalls will remain just south of highway 401,” Environment Canada said in the advisory. “Total snowfall amounts along the Lake Ontario shoreline near 20 cm are possible along with blowing snow due to southwesterly winds gusting near 60 km/h. Snow squall activity is expected to move south of the area Monday night.”
Snow squalls cause weather conditions to vary considerably, according to Environment Canada. “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. Consider postponing non-essential travel until conditions improve.”
