“Isaias is moving toward the northwest near 17 mph [28 km/h], and a generally northwestward motion with some decrease in forward speed is expected for the next couple of days followed by a turn toward the north-northwest. On the forecast track, the center of Isaias will move near or over the Southeastern Bahamas today.

“Isaias is forecast to be near the Central Bahamas tonight, and move near or over the Northwestern Bahamas and be near or east of the Florida peninsula on Saturday and Sunday.

“Maximum sustained winds are near 80 mph [130 km/h] with higher gusts. Some strengthening is possible today, and Isaias is expected to remain a hurricane for the next few days.
