.Synopsis for Massachusetts and Rhode Island coastal waters...
Other than late night and/or early morning fog, high pressure over
New England provides dry, tranquil boating weather through at least
Tuesday. Then mid to late next week, low pressure develops off the
Mid Atlantic coast and may drift northward. This may yield an
increase in the risk for showers and building southeast swells.
