Marine Weather HF Voice Broadcast for the Tropical N Atlantic
from 07N to 19N W of 55W, the N Atlantic from 19N to
31N W of 55W including the Bahamas, and the Caribbean Sea.
Seas given as significant wave height, which is the average
height of the highest 1/3 of the waves. Individual waves may be
more than twice the significant wave height.
Synopsis for Caribbean Sea and Tropical N Atlantic from
07N to 19N W of 55W
.SYNOPSIS...Moderate to fresh E to NE winds and moderate seas
are expected over much of the Caribbean through late Sat as low
pressure prevails over the south-central basin and high pressure
drifts eastward in the central Atlantic. Locally strong winds may
pulse offshore of Colombia late tonight. Mainly moderate trade
winds are then expected Sun into next week. Rough seas in E swell
will prevail east of the Lesser Antilles and through the
Atlantic Passages into early next week. Looking ahead, a cold
front may approach the NW Caribbean early next week.
