NANTUCKET, Mass.—Strong winds are causing problems for ferries running between Cape Cod and Nantucket.

The Steamship Authority says its 8 a.m. ferry from Hyannis was canceled on Thursday because of what it described as "extreme weather conditions."

Three ferries scheduled to travel from Nantucket to Hyannis were also canceled.

It was the third day in a row that some ferries had to be grounded.

The island is under a wind advisory posted by the National Weather Service through 2 p.m. Thursday. The forecast calls for winds of 25-35 mph with gusts of 45 mph.

A gale warning is also in effect until 4 p.m. for ocean waters off Massachusetts and Rhode Island.
