Synopsis for Caribbean Sea and Tropical N Atlantic from 07N to 19N between 55W and 64W .SYNOPSIS...Elongated low pres N of the basin along 71W-72W will help to maintain a weak pres gradient across the central and western Caribbean through Thu, supporting light to gentle winds. A pre-frontal trough will move into the NW Caribbean by Thu night where it will stall and linger through the end of the week, leading to a slight increase in winds and seas there. Over the E Caribbean, the Azores High will support gentle to moderate E-SE trade winds through the forecast period, locally fresh offshore northern Venezuela. Expect scattered showers and tstms across the waters E of 65W through tonight. Dispersing volcanic ash from recent eruptions of Popocatepetl Volcano in Mexico have shifted across the Yucatan Peninsula and into the NW Caribbean W of 83W, and are expected to linger through morning.
