A continued west-southwestward motion at a slow forward speed is expected through tonight, followed by a turn toward the northwest and north on Monday and Tuesday.

Oscar is then forecast to begin moving a bit faster to the northeast across the central Bahamas on Tuesday. Maximum sustained winds are near 80 mph (130 km/h) with higher gusts. After Oscar makes landfall, significant weakening is expected, but Oscar could still be a tropical storm when it moves north of Cuba late Monday and then moves across the central Bahamas on Tuesday. Hurricane-force winds extend outward up to 10 miles (20 km) from the center and tropical-storm-force winds extend outward up to 45 miles (75 km). Recently, there was a wind gust of 63 mph (101 km/h) from a weather station in Punta Maisi on the eastern tip of Cuba. The estimated minimum central pressure is 986 mb (29.12 inches). A weather station in Punta Maisi on the eastern tip of Cuba recently reported a minimum pressure of 998 mb (29.47 inches).
