SYNOPSIS
High pressure over the western Atlantic will support moderate to fresh trades and moderate seas through the next few days. Winds and seas will diminish somewhat late this week and into the weekend. Meanwhile, a mid to upper-level trough located just east of the southeastern Bahamas acting on a very moist and unstable environment will further support scattered showers and isolated thunderstorms across the regional waters going into the weekend. A tropical wave currently over the eastern Caribbean near 65W will also contribute to the unsettled weather conditions.
