Synopsis for Caribbean Sea and Tropical N Atlantic from 07N to 19N between 55W and 64W .SYNOPSIS...Elongated low pres N of the basin 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 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 SE trade winds through the forecast period, locally fresh offshore northern Venezuela. Expect scattered showers and tstms across the waters E of 65W through this evening. Popocatepetl Volcano in Mexico near 19N99W has been active and continues to erupt this morning. Volcanic ash has moved E to ESE away from the volcano and over the Bay of Campeche to the Caribbean coast of the Yucatan near Cozumel, S of 20N and W of 85W. Visibility may be restricted in this area due to volcanic ashfall through tonight. Mariners should exercise caution.
