Two storm systems we have been watching in the Atlantic Ocean since Friday, have changed significantly. The storm featured as #1 on Friday, is now #2 and the #1 storm, whether it becomes an organized, named storm or not, is forecast to bring heavy rain to the Caribbean Sea region.
As of 0800 hours this morning the storms have increased in likelihood to 80 percent and 50 percent. If the first storm is named it will be called Tropical Storm Franklin. If the second storm is named it will be called Tropical Storm Gert.
Showers and thunderstorms are showing some signs of organization in association with a strong tropical wave located over the west-central Caribbean Sea. This system is moving west-northwestward at 10 to 15 mph, and a tropical depression or tropical storm could form over the northwestern Caribbean Sea before it reaches the Yucatan Peninsula of Mexico late Monday or early Tuesday. Even if formation does not occur before the system reaches the Yucatan peninsula, a tropical depression or tropical storm could form over the Bay of Campeche by midweek. The Air Force Reserve reconnaissance aircraft scheduled for today has been canceled, but a new mission has been scheduled for Monday, if necessary. Interests along the coasts of Honduras, Belize, and the Yucatan Peninsula should monitor the progress of this disturbance. Formation chance through 48 hours, medium, 60 percent. Formation chance through 5 days, high, 80 percent.
An area of low pressure located about midway between the Cabo Verde Islands and the Lesser Antilles remains elongated, and the associated showers and thunderstorms are not well organized. Some slow development of this system is possible during the next several days while it moves generally west-northwestward across the tropical Atlantic at about 15 mph. Formation chance through 48 hours, low, 30 percent. Formation chance through 5 days, medium, 50 percent.
