Coade says Monday's storm has the potential to be the heaviest snowfall Nova Scotia has seen yet this winter. He says southern New Brunswick and Prince Edward Island will also receive at least 30 cms of snow.
But he says there's still a chance this system could change.
"There's still the possibility that it will be changing to rain or becoming mixed with rain along the Atlantic coast of Nova Scotia," he said.
The storm is on track to hit the south shore of Nova Scotia Monday afternoon and will be coupled with a strong northeast wind.
"I would say that everybody will see snow from this throughout the Maritime provinces. It will extend as far north as the Acadian peninsula and the Miramichi and so that will cover just about all of New Brunswick, Prince Edward Island and Nova Scotia."
The storm is expected to hit the Halifax area early Monday evening.
Around midnight, the nor'easter is likely to change to freezing rain and rain along the coastal parts of Nova Scotia.
Coade predicts the weather will clear by Tuesday morning.
