A powerful and perhaps historic Nor'Easter is developing this afternoon off the coast of North Carolina and is expected to move towards Cape Cod on Tuesday. Rapid intensification is expected with a 40-50 millibar pressure drop in less than 24 hours forecast. Heavy snow is already falling well in advance of the main storm across southern New England and metro New York City. Forecast blizzard conditions are expected overnight with accumulations reaching 12-24 inches and even up to 36" from metro NYC northeast into Massachusetts. Strong winds are forecast up to 65mph. Coastal flooding is also a big concern with warnings now posted. Thousands of flights have been cancelled already in northeast hubs with the prospect of a complete shutdown Tuesday in New York and Boston. A travel ban has been declared in Massachusetts for Tuesday. This storm could rival the historic Blizzard of 78. Away from the coast heavy snow is forecast northward into central Vermont and New Hampshire. Blizzard conditions are also forecast for New Brunswick, Nova Scotia and P.E.I. Heavy snow will fall along the Gaspe coast of Quebec.

Effects in Quebec
In southern Quebec strong northeast winds will develop on Tuesday gusting from 60km/h in metro Montreal up to 90km/h in Quebec City where warnings are in effect. Windchill values will be very cold with a high of only -11C expected and windchill readings down in the minus 20's. As far as snow goes, we are looking at 5cm for Montreal tomorrow evening, and upwards of 10-15cm for the Townships into the Beauce. Blowing snow will greatly reduce visibility in and east of Quebec City Tuesday night.
