Tropical-storm-force winds extend outward up to 105 miles (165 km) from the center.
The estimated minimum central pressure is 1006 mb (29.71 inches).
- The thunderstorm activity associated with a strong tropical wave that has moved off the west coast of Africa this morning is quickly becoming better organized. Environmental conditions are conducive for further development, and

Formation chance through 48 hours…high…90 percent.
Formation chance through 5 days…high…90 percent.
The Meteorological Department of St. Maarten will continue to monitor the progress of these systems and update the public accordingly.
