Synopsis

A broad area of high pressure will extend offshore from the Southeast U.S. coast through the middle of the week, with winds veering progressively easterly into Thursday. No significant boating hazards are expected through Friday, although increasing coverage of showers and a few lightning storms will return to the forecast into late week. Into the weekend, a passing front will lead to rapidly developing hazardous to dangerous boating conditions across the waters, which will likely persist into early next week.
