Good afternoon,
We continue to expect a strong ocean storm passing well southeast of Nantucket tonight and Saturday morning. This will bring strong winds to coastal areas, especially Cape Cod, Martha's Vineyard and Nantucket. Ocean areas will have strong winds and high seas.
Snow accumulations up to a few inches are forecast for the Cape, Martha's Vineyard and Nantucket. This could create slippery travel Friday night into Saturday morning.
Weather related headlines and specifics are listed below. In addition, the attached images include storm total snowfall, maximum wind gust in miles per hour (MPH) on land, and maximum wave heights in feet for the coastal waters.

- High Wind Warning for Cape Cod, Martha's Vineyard and Nantucket this evening through noon Saturday
