Synopsis for Caribbean Sea and Tropical N Atlantic from 07N to 19N W of 55W .SYNOPSIS...High pressure over the western Atlantic will maintain moderate to locally fresh trade winds across the basin, except for pulsing fresh to strong winds in the Gulf of Honduras at night through Mon night. Moderate to fresh trade winds over the central Caribbean are forecast to increase to fresh to strong speeds late Mon night through late Tue night, then shifting to between 75W and 80W for the rest of the forecast period. A tropical wave over the eastern Caribbean will continue to bring scattered to numerous showers and thunderstorms to this part of the Caribbean through Mon. Strong gusty winds and rough seas are likely with this activity. The wave may lose some definition as it moves across the central Caribbean during mid week. Dense smoke due to agricultural fires in Central America is likely to change over the Gulf of Honduras into the early part of the upcoming week.
