Synopsis for Caribbean Sea, and Tropical N Atlantic from 07N to
19N W of 55W
948 AM EDT Thu Oct 8 2026
.SYNOPSIS...Hurricane Isaias in the Gulf of America, and a
frontal boundary N of the Bahamas will maintain a weak pressure
gradient over the NW and SW Caribbean, supporting moderate or
weaker winds and slight seas through tonight. Moderate to fresh
trades in the central and eastern basin will prevail through Mon
as high pressure SE of Bermuda slowly drifts westward through Fri
evening before dissipating over the weekend. As a result, winds
are forecast to briefly reach moderate to fresh speeds over the NW
Caribbean on Fri. A tropical wave in the central Caribbean near
75W is accompanied by numerous thunderstorms between 70W and 75W.
The wave will move across the rest of the central Caribbean
through this evening and across the western Caribbean tonight
through the weekend. Moderate or weaker winds are forecast basin-
wide by late Mon as a cold front moves across the offshore waters
N of the Bahamas and helps to reduce the pressure gradient across
the region.
