In the Eastern Tropical Atlantic (AL98) Continues to show shower and thunderstorm activity in association with a broad area of low pressure located several hundred miles west of the Cabo Verde Islands. Environmental conditions are favorable for further development of this system and a short-lived tropical depression is likely to form this weekend while it moves west-northwestward or northwestward at about 10 mph. By early next week, upper-level winds are forecast to increase and further development is not expected.
Formation chance through 48 hours is 70 percent. Formation chance through 7 days is 70 percent.
In the Central Tropical Atlantic (AL99) an area of low pressure located roughly halfway between the Cabo Verde Islands and the Lesser Antilles is producing disorganized showers and thunderstorms to the east of its center. Environmental conditions are forecast to become increasingly unfavorable for further development of this system during the next day or two.
Formation chance through 48 hours is 30 percent. Formation chance through 7 days is 30 percent.
Closer to the Lesser Antilles (AL90) is a tropical wave located just east of the Windward Islands producing disorganized showers and thunderstorms. Some gradual development of this system is possible and a tropical depression could form during the early and middle parts of next week while it moves westward to west-northwestward at 10 to 15 mph.
Formation chance through 48 hours is 20 percent. Formation chance through 7 days is 40 percent.
Closer to home in the western Gulf of Mexico an area of disturbed weather located near the northwestern and central Bahamas is expected to move into the Gulf of Mexico by early next week, where a broad area of low pressure is expected to form. Some slow development of this system is possible thereafter and a tropical depression could form as it moves westward and approaches the western Gulf of Mexico coastline by the middle of next week.
Formation chance through 48 hours is 0 percent. Formation chance through 7 days is 50 percent.
