AccuWeather is providing live updates from D.C. here.

The forecasts have been superb, so far.

Here is the graph of snow accumulation for Washington, DC.

And, for New York:

These diagrams are the most recent composite computer model runs and I am showing them primarily for storm timing purposes. With very high winds, there will be extreme drifting and travel difficulties.

There will be power failures in some areas. In NY and other areas where the storm has not begun, please make final provisions.
