Tropical storm or hurricane conditions could affect portions of
Georgia, South Carolina, and North Carolina later this week or this
weekend, even if the center of Matthew remains offshore. It is too
soon to specify what, if any, direct impacts Matthew might have on
the remainder of the U.S. east coast farther north. At a minimum,
very dangerous beach and boating conditions are likely along much of
the U.S. east coast later this week and weekend.
