The US Coast Guard has shut down the ports to all traffic, meaning there is no travel from The Steamship Authority this morning. The Steamship is updating its website with information.
The National Weather Service has updated its advisory for the Cape, Coast and Islands: The region is now under a Storm Surge Watch and Buzzards Bay, Falmouth and Martha's Vineyard are under a Tropical Storm Warning. This is a downgrade from the previous Hurricane Watch issued for the area.
The window of concern for storm surge is early Sunday morning until early Monday morning. The National Weather Service is warning that life-threatening storm surge is possible with the potential for surge 2-4 feet above the ground.
Tropical Storm force winds are possible from Sunday morning until early Monday morning. Extremely strong winds can cause hazardous seas which could capsize or damage vessels and severely reduce visibility. The National Weather Service is urging mariners to remain in port, alter course, and/or secure their vessel.
Harbormasters around the region are urging boat owners to take necessary steps to protect their boats.
The Nantucket harbormaster will close the town pier on Saturday afternoon.
On Saturday, prior to the cancellation of the Hurricane Watch for the region and switch to a Tropical Storm Warning, Governor Charlie Baker said Sunday should be a "stay at home day" across the state, particularly on the Cape and Islands.

CAI will continue to monitor the storm on the Cape, Coast and Islands.
