A watch is typically issued 48 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area within 36 hours. A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 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 AM AST (0600 UTC), the center of Hurricane Larry was located near latitude 30.3 North, longitude 60.8 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 should pass east of Bermuda today, and move near or over southeastern Newfoundland late Friday. Maximum sustained winds are near near 100 mph (155 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 remains very large, with Hurricane-force winds extending 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 969 mb (28.62 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Larry can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT2, WMO header WTNT42 KNHC and on the web at hurricanes.gov/graphics_at2.shtml?key_messages WIND: Tropical storm conditions are expected on Bermuda beginning later this morning. 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. RAINFALL: Outer rain bands from Hurricane Larry may periodically impact Bermuda today. Significant rainfall totals are currently not expected, however briefly heavy rain rates within these bands may result in an inch or two of rain.
