Preparations to protect life and property should be rushed to completion. A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area, in this case within the next 12 hours. Interests elsewhere in southeastern Newfoundland should monitor the progress of this system. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 200 PM AST (1800 UTC), the center of Hurricane Larry was located near latitude 41.8 North, longitude 59.5 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 remain 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).

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.
