How Much Snow?

The forecast map below shows the heaviest accumulations in the pink shadings, mainly just to the west and northwest of the I-95 corridor. This is where at least 6 inches is expected. Dark purple shading indicates the potential for a foot or more of snow. The heavy, wet nature of the snow will likely cause tree damage and power outages.

Some accumulations are also possible closer to the coast along the heavily-populated I-95 corridor from near Washington, D.C. to Boston. Precipitation will start as rain in these locations, but may change over to snow. How quickly this occurs and how much snow falls is dependent on the availability of enough cold air, which is difficult to forecast early in the season.

Power Outage Potential

As mentioned before, this will be a heavy, wet snow. Combine this with wind from the intensifying low-pressure system off the coast and power outages are likely in the darker blue-shaded area on the map below. Outages are also possible in locations closer to the coast from the wind alone. The map below shows the power outage potential across the Northeast.
