Snow squalls could bring more than 15 centimetres of snow and cause poor or zero visibility near Picton and Kingston, according to Environment Canada.
The agency issued a snow squall warning early Sunday morning for Picton, Ont. To the northeast, Kingston, Odessa and the Frontenac Islands are under a snow squall watch.
Snow squalls were affecting Picton Sunday morning and are expected to continue though the afternoon, Environment Canada said. Its watch noted the squalls could move far enough north to affect the Kingston region before shifting south in the evening.
Weather conditions will be variable, the agency warned, writing that “changes from clear skies to heavy snow within just a few kilometres are common.”
Anyone who’s travelling should prepare for conditions that could quickly change or deteriorate, Environment Canada said.
According to Kingston’s forecast, the snow should taper off Sunday night, with a mix of sun and clouds on Monday.
The public can monitor changes to the situation on Environment Canada’s website.
