DISCUSSION AND OUTLOOK ---------------------- At 1100 AM AST (1500 UTC), the center of Hurricane Larry was located near latitude 32.0 North, longitude 61.6 West. Larry is moving toward the north-northwest near 16 mph (26 km/h), and a turn toward the north with an increase in forward speed is forecast today, with a faster northeastward motion expected by Friday. On the forecast track, the center of Larry will pass east of Bermuda today, and move near or over southeastern Newfoundland Friday night or early Saturday morning. Maximum sustained winds are near 90 mph (150 km/h) with higher gusts. Gradual weakening is forecast during the next couple of days, but Larry is expected to remain a hurricane during that time. Larry should become an extratropical cyclone early Saturday, after passing by Newfoundland, then weaken further while it passes southeast of Greenland Sunday night. Larry is expected to be absorbed by a larger extratropical low east of Greenland by Monday. Larry is 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 220 miles (350 km). The estimated minimum central pressure is 966 mb (28.53 inches).
