Tropical storm or hurricane conditions could affect 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 to the north. At a
minimum, dangerous beach and boating conditions are likely
along much of the U.S. east coast later this week and weekend.
