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.

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
the weekend. Gentle winds prevail 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 near 32.7N 61.3W at 11 PM
EDT, and is moving north-northwest at 4 kt. Maximum sustained
winds are 50 kt with gusts to 60 kt, and the minimum central
pressure is 991 mb. Tammy will move to 32.9N 60.3W Sat morning,
32.6N 57.9W Sat evening, 31.9N 55.0W Sun morning, 30.5N 52.7W
Sun evening, weaken to a tropical depression near 29.1N 51.6W
Mon morning, and become a remnant low and move to 28.2N 51.6W
Mon evening. Tammy will change little in intensity as it moves
to 28.1N 52.2W by late 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.
