Maritimers awoke to a cold dawn Friday and the expectation of the second major winter storm in a week.

Temperatures were in the -20s in much of the region Friday morning. The advancing storm will bring warmer temperatures through the day. When it starts overnight it will also bring as much as 30 centimetres of snow to eastern parts of the Maritimes before winding down on Sunday.

"A low pressure system now over the lower Great Lakes will combine with another over Cape Hatteras to form a rapidly intensifying ocean storm that will meet the criteria of a weather bomb," said CBC meteorologist Jim Abraham.

"This storm will pass south of Nova Scotia while moving relatively slowly on Saturday."

For the latest on this storm, please stay with CBC News today and through the weekend.

CBC meteorologist Kalin Mitchell will have the most up-to-date track on CBC TV tonight and 5 and 11.

He'll also continue to track this storm on Saturday online, on radio and on CBC Maritimes at 7.

Our Storm Centre website will be updated constantly at cbc.ca/stormcentre.

And we'll have reporting teams hard at work right across the Maritimes.

While a blizzard warning is in effect for most of the region, the Maritimes is only getting the edge of the storm. Boston will be hit by its full winter wrath. Meteorologists there are saying storms of that magnitude are only witnessed a handful of times over the course of a career. As much as 60 centimetres of snow is expected.

While there will not be as much snow north of the border, travel conditions will be extremely poor.  Temperatures are forecast in the -4C to -6C range, making for a dry snow easily blown around in the high winds.

Event cancellations are already coming in to CBC's Storm Centre site in Nova Scotia and P.E.I.
