Synopsis for Caribbean Sea and Tropical N Atlantic from 07N to 19N between 55W and 64W .SYNOPSIS...Weak low pressure off the coast of Colombia was producing fresh winds in the south-central Caribbean earlier today. However, the associated shower and thunderstorm activity with this system remains disorganized, and nearby dry air is forecast to prevent much additional development as the system begins to drift slowly westward over the next few days. This system has a low chance of formation in the next 48 hours and 7 days. Meanwhile, high pressure building toward the Greater Antilles Tue into Wed will lead to fresh to strong NE winds in the Windward Passage and just S of Hispaniola. Elsewhere, winds will be moderate or less into late week. NW Caribbean W of 85W .TONIGHT...E winds 10 to 15 kt.
