 .SYNOPSIS...High pressure off the Carolina Coast will maintain
 mainly fresh easterly breezes through this evening with hazardous
 marine conditions continuing. As the high continues to slowly
 migrate into the western North Atlantic, breezes will continue to
 slowly slacken as well as shift to the east to southeast. Weak
 high pressure maintains control over the weekend promoting light
 to gentle east to southeast breezes.
