Marine Weather HF Voice Broadcast for the Tropical N Atlantic
from 07N to 22N between 55W and 64W, the SW N Atlantic S of
31N W of 65W including 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 between 55W and 64W

.SYNOPSIS...Strong high pressure centered over the middle
Atlantic U.S. coast is combining with elongated low pressure
extending from the W central Atlantic across the NE Caribbean
will support fresh to strong NE to E winds in the NW and
north-central Caribbean, including the Windward Passage through
Sun. Gentle winds are expected elsewhere. Large N-NE swell
across the W Atlantic will continue to move through the NE
Caribbean Passages through Sun. Broad low pressure is expected
to develop over the W central Caribbean by Sun and move slowly
northward and into the Bahamas through Tue.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...Tropical Storm Tammy is located near 32.5N 61.4W
988 mb at 2100 UTC, moving NW at 3 kt. Maximum sustained winds 
are 55 kt gusting to 65 kt. Tammy is expected to turn NE tonight 
and then move E to SE over the weekend, and will brush the far NE
offshore waters Sat and Sat night, then gradually weaken E of 
55W through Tue. High pressure across the middle Atlantic coastal
states is combining with a low level trough than extends from S 
of Tammy to the NE Caribbean to produce a large area of fresh to 
locally strong winds, with very high seas between Tammy and the 
Bahamas. These high seas will slowly subside Sat through Sun. 
Elongated low pressure will develop across the SE Bahamas Sun and
gradually drift NW through Tue.
