In an already brutal winter, the storm approaching Atlantic Canada right now might be the one that's talked about the most.

Officials are already expecting widespread travel delays, and residents are being warned to prepare for outages and closures when a powerful storm grips the region mid-week.


ATLANTIC CANADA: Six things to know about the coming Nor'easter


As coverage intensifies here at The Weather Network, you may start to hear a few weather terms being floated around on air and on our website.

Here are some of them, along with their definitions.

1. NOR'EASTER

The storm that's set to impact Atlantic Canada is "like a Nor'easter on steroids," says Weather Network meteorologist Matt Grinter.

A Nor'easter is a cyclonic winter storm that occurs off the east coast of North America. They're known to generate a lot of snow and rain, along with powerful waves. Wind, in some cases, can meet or exceed hurricane strength. The name "Nor'easter" is a nod to the northerly winds associated with these systems. 

2. STING JET

Sting jets are a complex weather phenomenon, "but in layman's terms, they're essentially an area of strong winds associated with a deepening depression in the atmosphere that can descend to the surface to produce damaging winds," Grinter says.

3. STORM SURGE

"Storm surge is an abnormal rise of water generated by a storm, over and above the predicted astronomical tide," writes the National Oceanic and Atmospheric Administration (NOAA). This is a common characteristic of a Nor'easter.

4. WRECKHOUSE AND LES SUÊTES WINDS

Wind warnings are nothing new to residents of Atlantic Canada -- but you may be surprised to learn that certain warnings have been developed to target specific regions.

Environment Canada has criteria that must be met before a weather watch or warning is issued in a particular area -- but the winds in Nova Scotia's Inverness County and Wrekchouse, Newfoundland are so strong that they have their own criteria.

"Les Suêtes wind warnings are associated with Inverness County and are issued when sustained winds are at 70 km/h or more with gusts to 90 km/h or more," Grinter says.

"Wreckhouse wind warnings are issued when the Wreckhouse area of the west coast of Newfoundland experiences sustained winds of 80 km/h with gusts to 100 km/h or more."

No wind warnings are currently in effect in Atlantic Canada, but that could change as the system moves.
