Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...Tropical Storm Jerry is near 22.7N 63.9W at 11 PM
EDT, and is moving north at 13 kt. Maximum sustained winds are
50 kt with gusts to 60 kt, and the minimum central pressure is
1004 mb. Jerry will move to 24.6N 63.3W Sat morning, 27.4N 62.7W
Sat evening, 29.6N 62.0W Sun morning, 31.3N 60.8W Sun evening,
32.0N 58.9W Mon morning, and become post-tropical and move to
31.4N 56.4W Mon evening. Jerry will change little in intensity
as it moves to the 29.8N 51.6W late Tue. Tight pressure gradient
just south of Bermuda result in strong to near gale-force E
winds and rough seas. These conditions will shift north of our
waters Sat afternoon. Meanwhile, developing low pressure system
centered offshore of north-central Florida will move northeastward
through the weekend. The associated cold front will extend from
the low center across south Florida into the SE Gulf of America.
Fresh to near gale- force winds and rough seas are expected on
either side of the front late tonight through Mon. The front is
forecast to move slowly SE and dissipate by Mon and the marine
conditions will improve by Tue.
