Environment and Climate Change Canada meteorologists say a potentially major winter storm might begin to affect the Maritimes Tuesday afternoon and go into Wednesday.
In an update Sunday morning, they say the system has yet to develop and few details are known for certain. But forecasters are saying current information suggests significant snowfall, rain or freezing rain, very strong northeasterly winds and higher than normal water levels.
They say slight shifts in the track of the low pressure system could significantly change precipitation type and duration, especially along the Atlantic coast and northeastern regions including Cape Breton.
On Monday morning, Environment Canada issued a winter storm watch.
