Ten states were under a high wind warning Friday, which was issued for sustained winds of at least 35 mph, or gusts exceeding 55 mph.
While the winds in New England were onshore creating an enormous tidal surge on the coast, they were away from the shore in the Mid-Atlantic resulting in bays and tidal basins emptying in a phenomenon known as a blowout.
