Southwestern Nova Scotia is bracing for a blast of winter, with the forecast calling for up to 20 centimetres of snow Sunday in some parts of the province.

Environment Canada issued snowfall warnings Saturday for central Nova Scotia — including Halifax — and along the southwestern coast of the province.

Fifteen to 20 centimetres of snow are expected by late Sunday evening.

Meteorologist Ted McIldoon said a small low-pressure system is expected to bring about five centimetres of snow Sunday morning.

He said a second low-pressure system should then form south of Cape Cod and intensify as it heads north Sunday evening and early Monday morning.

McIldoon said the snowfall warning could also extend to central Prince Edward Island.

“It will eventually line up as a fairly major storm up in the Gulf of St. Lawrence,” McIldoon said Saturday from Halifax.

In eastern parts of Nova Scotia, snow is expected to change to rain and possibly freezing rain late Sunday.

“The worst of the precipitation will be the early hours of Monday morning,” McIldoon said, adding that it could eventually change back to snow.

“Monday looks like a messy day to say the least.”

High winds are also on the way for eastern Nova Scotia, but MicIldoon said it’s too early to predict how strong they will be.
