DISCUSSION AND OUTLOOK ---------------------- At 500 AM AST (0900 UTC), the center of Hurricane Larry was located near latitude 37.7 North, longitude 61.8 West. Larry is moving toward the north-northeast near 26 mph (43 km/h). A turn to the northeast with a further increase in forward speed is expected today. On the forecast track, the center of Larry will pass well southeast of Nova Scotia today, and move over southeastern Newfoundland tonight. Maximum sustained winds are near 85 mph (140 km/h) with higher gusts. Gradual weakening is forecast during the next day or so, but Larry is expected to remain a hurricane until it passes Newfoundland. Larry should become an extratropical cyclone on Saturday, and is now forecast to be absorbed by a larger extratropical low near Greenland by the end of the weekend. Larry remains a large hurricane. Hurricane-force winds extend outward up to 90 miles (150 km) from the center and tropical-storm- force winds extend outward up to 240 miles (390 km). The estimated minimum central pressure is 968 mb (28.59 inches).
