.SYNOPSIS...
Offshore winds this morning will shift southeasterly behind the
afternoon sea breeze. A weakening front will stall north of the
waters
tonight and dissipate through Sunday as another front pushes into
the southeastern US early next week. This will promote nightly
southeasterly wind surges to Exercise Caution levels, mainly
offshore through at least the middle part of next week. The
predominant offshore flow next week will strengthen with the second
front and increase chances afternoon thunderstorms are steered into
and develop across the coastal waters.
