At 500 PM AST (2100 UTC), the center of Tropical Storm Sebastien was located near latitude 20.6 North, longitude 59.7 West. Sebastien is moving toward the northwest near 12 mph (19 km/h). A turn to the north is expected on Wednesday followed by a turn to the northeast with an increase in forward speed Wednesday night.

The estimated minimum central pressure is 1006 mb (29.71 inches).
