Synopsis for Caribbean Sea and Tropical N Atlantic from 07N to 19N between 55W and 64W .SYNOPSIS...Elongated low pres from the SE Bahamas to 30N70W 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 E-SE trade winds through the forecast period, locally fresh offshore northern Venezuela.
