At 11 AM the center of Topical Depression 11 was located near latitude 13.2 North, longitude 53.5 West or about 700 miles southeast of St. Maarten. The system is moving slowly toward the west at 3 mph. A westward to west-northwestward motion at a slightly faster forward speed is expected during the next couple of days. Maximum sustained winds have decreased near 30 mph with higher gusts. The estimated minimum central pressure is 1008 mb (29.77 inches).
Tropical depression 11 is forecast to become a remnant low on Sunday and dissipate east of the Lesser Antilles Sunday night. As a result, this system does not pose a threat to St. Maarten.
