Synopsis for Caribbean Sea and Tropical N Atlantic from 07N to 19N W of 55W .SYNOPSIS...Major Hurricane Milton is near 23.4N 86.5W at 11 PM EDT, and is moving northeast at 10 kt. Maximum sustained winds are 140 kt with gusts to 175 kt, and the minimum central pressure is 915 mb. Milton will move to 24.7N 85.3W Wed morning, 26.5N 83.6W Wed evening, inland to 27.9N 81.4W Thu morning, 28.5N 78.8W Thu evening, 29.0N 75.5W Fri morning, and weaken as an extratropical cyclone near 29.4N 72.0W Fri evening.

Elsewhere, winds may freshen in the eastern Caribbean midweek, spreading to the central Caribbean at the end of the week as a tropical wave moves across the area.

Maximum sustained winds are 140 kt with gusts to 175 kt, and the minimum central pressure is 915 mb. Milton will move to 24.7N 85.3W Wed morning, 26.5N 83.6W Wed evening, inland to 27.9N 81.4W Thu morning, 28.5N 78.8W Thu evening, 29.0N 75.5W Fri morning, and weaken as an extratropical cyclone near 29.4N 72.0W Fri evening. Milton will change little in intensity as it moves near 30.4N 65.0W late Sat. Expect increasing winds and building seas in advance of Milton over waters east of Florida on Wed into Wed night. Meanwhile, 1002 mb low pressure near 28N73W is producing gale force winds SE of the low center. The low will shift NE with gales continuing in the SE quadrant until the low moves N of the area Wed night. Environmental conditions appear only marginally favorable for additional tropical or subtropical development over the next day or so while the low moves northeastward to east-northeastward at around 15 mph. Upper-level winds are likely to increase further by Wednesday night, which should end any chances for further development. This system has a low chance of development in 48 hours and 7 days. Farther E, swells associated with Hurricane Leslie, forecast to remain E of the area, may impact the waters E of 60W Wed into Thu.
