A tropical storm has formed in the Atlantic, and it could be heading toward North Carolina.  Tropical Storm Isaias formed Wednesday evening and is currently situated near Puerto Rico.  Isaias currently has maximum sustained winds of 60 mph.  The latest storm track shows Isaias heading northwest toward Florida before making a turn and heading up the southeast Atlantic coast, possibly directly toward North Carolina.  If that track holds, Eastern Carolina could begin to feel the winds from the storm by late Sunday or early Monday.
