Maximum sustained winds 30 kt gusts 40 kt. Thirteen will move to 16.4N 52.7W this afternoon and strengthen to a tropical storm near 17.5N 56.4W Fri morning. The tropical storm will then reach near 18.4N 60.2W Fri afternoon, 19.1N 63.9W Sat morning, 19.8N 67.1W Sat afternoon, and 20.8N 71.0W Sun morning. Thirteen is forecast to remain a tropical storm as it passes near eastern Cuba and the southeastern Bahamas early Mon. This system could impact portions of the eastern Gulf of Mexico early next week. Meanwhile, low pressure over the central Caribbean Sea this morning has a high chance of tropical formation in the northwest Caribbean within a couple of days.
