The East Coast storm is currently intensifying about 10-15 miles east of Ocean City, Md., and will continue to track north-northeast with the center of the storm reaching the Bay of Fundy by early Friday afternoon.

We shifted the accumulating snow a little more toward the west through Quebec and toward Ottawa, but the heaviest snow will still run up through Maine and into northern New Brunswick and the Gaspe tonight into Friday.
Even where the snow changes over to a mix or rain, there will still be a significant accumulation as the snow will come down fast and furious on the front side of the storm with the potential for snowfall rates as high as 5 cm per hour.
Wind will also be an issue, especially over coastal Nova Scotia, including Cape Breton, early Friday morning with southeast gusts in excess of 90 km/h. Expect Les Suetes in the Cheticamp area with gusts of at least 110 km/h. The strong winds will reach southeastern Newfoundland Friday evening.
Friday snapshot of the storm..
I expect about 10-15 cm of snow in the St. John's, NL, area Thursday night before changing over to sleet then rain by Friday morning with increasing south to southwest winds.
A second storm will follow this storm and will likely bomb out east of Cape Cod then track northeast toward eastern Nova Scotia later Saturday.
This is our initial snow forecast map (in inches) for the Friday-Sunday storm.
This storm has the potential to bring blizzard conditions (strong winds) and over 30 cm of snow to parts of New Brunswick, western PEI and northwestern Nova Scotia Saturday into Saturday night. Depending on the track, the snow could change to a mix or rain over central/eastern Nova Scotia then into Newfoundland.
