DISCUSSION AND OUTLOOK ---------------------- At 1100 PM AST (0300 UTC), the center of Hurricane Larry was located near latitude 35.5 North, longitude 62.3 West. Larry is moving toward the north near 25 mph (41 km/h). A further increase in forward speed is expected tonight with a turn to the northeast forecast by Friday. On the forecast track, the center of Larry will continue to move away from Bermuda tonight, 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 to begin on Friday, 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 230 miles (370 km). The estimated minimum central pressure is 966 mb (28.53 inches).

Tropical storm conditions are expected in the tropical storm warning area in southeastern Newfoundland by late Friday. STORM SURGE: A dangerous storm surge is expected to produce coastal flooding within the warning areas in southeastern Newfoundland. SURF: Swells generated by Larry will continue to affect the Leeward Islands, portions of the Greater Antilles, the Bahamas, and Bermuda through the end of the week. Significant swells from Larry will continue affecting the east coast of the United States and Atlantic Canada through the end of the week. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
