Synopsis for the SW N Atlantic including the Bahamas
440 AM EDT Thu Aug 13 2026
.SYNOPSIS...The western Atlantic ridge extends from 50W, westward
along 27N to SE Florida, and will sink slightly southward Fri and
Fri night, before weakening over the weekend into early next
week. S of 23N, trade winds will freshen from E to W today through
Sat, behind a tropical wave currently across the eastern
Caribbean. Fresh trades N of Hispaniola and in the approach to the
Windward Passage will pulse to strong speeds each night. Looking
ahead, an area of showers and thunderstorms associated with a
strong tropical wave located over the central Atlantic near 42W is
showing some signs of organization. Environmental conditions are
forecast to be conducive for development during the next day or
so, and a tropical depression will likely form while the system
moves westward to west- northwestward across the central tropical
Atlantic. However, by Friday, upper-level winds are likely to
become too strong for development as the system approaches the
Lesser Antilles. This system is forecast to reach the Lesser
Antilles Sat morning, and reach 70W Sun morning.
