DISCUSSION AND OUTLOOK ---------------------- At 500 AM EDT (0900 UTC), the center of Hurricane Oscar was located near latitude 21.1 North, longitude 73.1 West. Oscar is moving toward the west near 12 mph (19 km/h). A west-southwestward or westward motion at a slower forward speed is expected through tonight, followed by a turn toward the northwest and north on Monday and Tuesday. On the forecast track, the center of Oscar will move across Great Inagua this morning, make landfall along the northeastern coast of Cuba later this afternoon or evening, and then move across eastern Cuba tonight and Monday. Oscar will then accelerate northeastward across the central Bahamas on Tuesday. Maximum sustained winds are estimated to be near 80 mph (130 km/h) with higher gusts. Oscar is forecast to reach the northeastern coast of Cuba as a hurricane later this afternoon. Weakening is expected after landfall, but Oscar could still be a tropical storm when it moves north of Cuba late Monday and moves across the central Bahamas on Tuesday. Hurricane-force winds extend outward up to 5 miles (10 km) from the center and tropical-storm-force winds extend outward up to 45 miles (75 km). The estimated minimum central pressure is 988 mb (29.18 inches).
