Disturbance 1. A low pressure system located about 150 miles east of Barbados is likely to develop into a tropical depression later today or tonight while the low moves west-northwestward at 10 to 15 mph. The disturbance is forecast to reach portions of the Lesser Antilles tonight, then move near the Virgin Islands and Puerto Rico on Tuesday, and be near Hispaniola around the middle of this week. Tropical storm watches or warnings could be required today with shorter-than-normal lead times for portions of the Lesser Antilles, the Virgin Islands, and Puerto Rico. Formation chance through 48 hours is at 70% and formation chance through 5 days is also high at 70%.
It's too soon to say whether this system will bring impacts to the local area or even enter the Gulf of Mexico.
Disturbance 2. An elongated low pressure area located several hundred miles east of the Lesser Antilles is becoming less likely to develop during the next few days while it moves toward the west or west-southwest at around 10 mph. Formation chance through 48 hours is at 10% and formation chance through 5 days is at 20%.
