At 11:00 AM (1500 UTC), the center of tropical storm Fiona was located near latitude 16.0 North, longitude 59.4 West or about 284 miles southeast of St. Maarten. Fiona is moving toward the west near 14 mph (22 km/h). This general motion with a decrease in forward speed is expected through early Sunday, followed by a turn toward the west-northwest and northwest on Sunday and Sunday night. On its present forecast track, the center of Fiona is forecast to pass at its closest approximately 100 miles south west of St. Maarten Saturday morning. However, impacts are likely from later today.
Data from a Hurricane Hunter aircraft indicate that maximum sustained winds are near 50 mph (85 km/h) with higher gusts. Gradual strengthening is forecast during the next few days. Tropical-storm-force winds extend outward up to 140 miles (225 km) from the center. The estimated minimum central pressure is 1005 mb (29.68 inches).
