Weather Network forecasters are keeping a close eye on a nor'easter brewing in the Atlantic Ocean, which is set to be a powerful storm by the time it begins to effect Atlantic Canada.

The storm will potentially have a large impact on those winter-weary provinces, and we'll be monitoring the situation continuously as the storm approaches the region.

Here are six things people in the region need to know to prepare for its arrival.

When is it coming?

Indications are the nor'easter will begin to effect the region late Tuesday overnight, strengthening into Wednesday through the Maritimes, with several hours of blowing snow. 

In Newfoundland, the real force of the storm will begin Wednesday overnight, with strong winds lasting through the day Thursday into early Friday morning as the system moves beyond the region.

How much snow could fall?

Nova Scotia, southern New Brunswick and Prince Edward Island are all on track for significant amounts of snow, with western Nova Scotia being hit the hardest.

Southern Newfoundland could see up to 25 cm, also, but that province in particular will be most affected by strong winds. More on that in a moment.

Will there be mixed precipitation?

At the moment, Nova Scotia in particular is at risk for some of that snow turning to rain as Wednesday progresses.

Expected amounts are expected to be less than 15 mm, but where mixing occurs, it will be along most of Nova Scotia's southern coasts, and most of Cape Breton Island.

How strong will the winds be?

Forecasters are already talking about 'hurricane force' winds for much of the region, depending on the day.

By Wednesday morning, winds just off New Brunswick's Fundy Coast and Nova Scotia's South Shore could be up to 150 km/h, with weaker, but still very strong gusts onshore. Strong winds will persist through the Maritimes on Thursday even after the worst of the storm has departed.

Newfoundland, meanwhile, is expected to see gusts of more than 100 km/h at St. John's by Wednesday night, and very strong winds are expected to ebb and flow all the way through to the early morning hours on Friday.

All the Atlantic Provinces have experienced power outages over the past winter, and the strong winds with this system are expected to challenge the region's power grids once again.

Will there be storm surge?

Aside from the storm's very strong winds, the storm is expected to be a significant low pressure event, and even features a well-defined 'eye' in radar images.

It is too soon to say, but at the moment it seems major storm surge along coastal communities is very likely.

Have any watches or warnings been issued?

As of 10 a.m. Sunday, no watches or warnings are in effect for the Atlantic Provinces. However, that will certainly change as the storm approaches and forecasts firm up.

The Weather Network will be following this storm very closely. Watch our ongoing coverage on TV, and check our warnings page for updates on your area. If you want to join the conversation, we'd love to hear from you. Be sure to tweet us @weathernetwork using #Noreaster.
