Synopsis for Caribbean Sea and Tropical N Atlantic from 07N to 19N between 55W and 64W .SYNOPSIS...A surface to low-level trough accompanied by scattered and thunderstorms extends from the southern Yucatan Peninsula to a 101 mb low near 16N82W and continues southeastward to a 1009 mb low over northwestern Colombia near 10N75W. It will change little through Wed. Weak Atlantic high pressure will remain centered across the central Atlantic through Thu before shifting northeastward. A tropical wave currently along 54W will reach the Windward Islands and the eastern Caribbean Sea by midweek and the western Caribbean over the weekend. Slow development of this system is possible during the next several days while the wave moves generally westward. Interests in the Windward Islands should monitor the progress of this system. Elsewhere, gentle to moderate trades and slight to moderate seas are expected across the basin through late Wed. Fresh northeast winds then develop out ahead of the tropical wave through Sat night.
