This upcoming storm is a very unusual storm for March, but certainly not unprecedented. The arrival of bitterly cold air into Southern New England Sunday night will help to create this very powerful storm. The worst of the snow/wind is expected to remain to the east of Rhode Island.
Here we will discuss, the Watches in place as well as the potential impacts the storm will have on us…including snow accumulations.
The National Weather Service has issued a Winter Storm Watch for Newport County in Rhode Island and Bristol and Plymouth Counties in Massachusetts. A Blizzard Watch is in effect for Cape Cod and the Islands.
In this case, a Winter Storm Watch means that there is the potential for 6″ or more of snow in the areas in blue above. The combination of strong winds and a period of heavy snow could create difficult driving conditions late Tuesday and Wednesday.
A Blizzard Watch means that blizzard conditions are possible. This is due to a combination of falling snow and frequent strong wind gusts creating very poor visibility or white out conditions for a period of 3hours or more.
In addition, Coastal Flood Watch is in effect for Cape Cod…mainly the north-facing and ocean-side shores of the Cape around the time of high tide Wednesday morning (8-9am).
As far as snow accumulations go, here’s an early look at what to expect. This could change, so please check back.

- As is always the case, this is very track dependent.

Please be sure to check back to later forecasts. The storm could have more of an impact (or less of an impact) depending upong the exact track of the storm, which is still a little uncertain.
