It's shaping up to be another weekend of rough surf along parts of the East Coast.
For the second weekend in a row, a tropical weather system is threatening to stir up waves and rip currents from the Carolina coast to New England.
It's just the kind of conditions surf instructor Dave Houck likes: swells without the "mess" of a storm coming ashore. He was at Carolina Beach, N.C. Friday coaching some students.
One marina on the North Carolina island of Ocracoke says warnings of rough seas prompted a rash of cancellations of overnight docking space.
The National Weather Service says Tropical Storm Danny could produce swells as high as 7 feet offshore.
A tropical storm watch is in effect for much of the North Carolina.
As of 11 a.m., Eastern time Friday, Danny was about 350 miles south of Cape Hatteras, N.C., with winds of 40 mph. It's been moving west but forecasters expect it to turn toward the northeast.
