DISCUSSION AND OUTLOOK ---------------------- At 1100 AM AST (1500 UTC), the center of Hurricane Larry was located near latitude 40.0 North, longitude 60.5 West. Larry is moving quickly toward the north-northeast near 29 mph (46 km/h). An even faster north-northeast to northeast motion is expected during the next day or two. 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 80 mph (130 km/h) with higher gusts. Little change in strength is expected before landfall in Newfoundland. After landfall, Larry should weaken and become an extratropical cyclone on Saturday before it merges with another low over the Labrador Sea on Sunday. Larry is a large tropical cyclone. 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 971 mb (28.68 inches).

Tropical storm conditions are expected to begin in the tropical storm warning area in southeastern Newfoundland later today. 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 Bahamas today. Significant swells from Larry will continue affecting Bermuda, the east coast of the United States, and Atlantic Canada through Saturday night. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. RAINFALL: Heavy rains from Larry will move quickly across eastern Newfoundland tonight, producing 1 to 2 inches of rain. NEXT ADVISORY ------------- Next intermediate advisory at 200 PM AST.
