Synopsis for Caribbean Sea and Tropical N Atlantic from
07N to 19N W of 55W

.SYNOPSIS...Tropical Storm Beryl is near 9.3N 43.6W at 11 PM
EDT, and is moving west at 16 kt. Maximum sustained winds are
35 kt with gusts to 45 kt, and the minimum central pressure is
1006 mb. Beryl will move to 9.7N 46.2W Sat morning, 10.4N 49.7W
Sat evening, 11.0N 53.1W Sun morning, strengthen to a hurricane
near 11.7N 56.5W Sun evening, 12.5N 60.0W Mon morning, and 13.6N
63.6W Mon evening. Beryl will change little in intensity as it
moves to 16.0N 71.0W late Tue, then to 17.8N 77.8W late Wed.
Meanwhile, a broad area of low pressure over the NW Caribbean
Sea accompanied by a tropical wave will support fresh to strong
E to SE winds and building seas in the NW Caribbean through the
Yucatan Channel through Sat night. The system is then forecast
to move west-northwestward, emerging over the Bay of Campeche
Sat night or early Sun, where conditions appear generally
conducive for further development, with the potential for
tropical cyclone formation. Otherwise, mainly moderate to fresh
trades will prevail, pulsing to fresh to strong in the central
Caribbean as a tropical wave moves through later in the weekend
into early next week.
