DISCUSSION AND OUTLOOK ---------------------- At 1100 AM AST (1500 UTC), the eye of Hurricane Larry was located near latitude 19.5 North, longitude 49.7 West. Larry is moving toward the northwest near 13 mph (20 km/h). A northwestward motion with a slight decrease in forward speed is expected during the next few days. Maximum sustained winds are near 125 mph (205 km/h) with higher gusts. Larry is a category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale. Little change in strength is forecast during the next few days, although fluctuations in intensity will be possible. Larry is expected to remain a major hurricane through the middle of this week. Larry is a large hurricane. Hurricane-force winds extend outward up to 45 miles (75 km) from the center and tropical-storm-force winds extend outward up to 175 miles (280 km). The estimated minimum central pressure is 955 mb (28.20 inches). HAZARDS AFFECTING LAND ---------------------- SURF: Swells generated by Larry are expected to reach the Lesser Antilles today, and will spread westward to portions of the Greater Antilles, the Bahamas, and Bermuda on Monday and Tuesday. Significant swells will likely reach the east coast of the United States and Atlantic Canada by midweek. These swells are likely to cause life-threatening surf and rip current conditions.
