DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 200 PM AST (1800 UTC), the center of Post-Tropical Cyclone Hermine was located near latitude 39.1 North, longitude 69.2 West. The post-tropical cyclone is moving toward the northwest near 6 mph (9 km/h), and a turn toward the north with decreasing forward speed is expected over the next day or two. On the forecast track, the center of Hermine will meander slowly offshore of the New England coast through Tuesday. Maximum sustained winds are near 70 mph (110 km/h) with higher gusts. Hermine should remain near hurricane strength today. A gradual weakening trend is forecast to begin on Tuesday morning. Tropical-storm-force winds extend outward up to 230 miles (370 km) from the center. Nantucket Island recently reported a sustained wind of 39 mph (63 km/h) with a gust to 52 mph (83 km/h). The minimum central pressure estimated from Air Force reconnaissance aircraft observations is 997 mb (29.44 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions will continue to spread over portions of the warning area later today and tonight. STORM SURGE: The combination of a storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline. Along the immediate coastline, the surge will be accompanied by large and dangerous waves. The water could reach the following heights above ground if the peak surge occurs at the time of high tide... Coast of Long Island from Fire Island Inlet to Port Jefferson Harbor...1 to 2 feet RAINFALL: Hermine will produce total rain accumulations of 1 to 2 inches across eastern Massachusetts, including Cape Cod and the offshore islands, through Wednesday. SURF: Large waves generated by Hermine will affect the U.S. east coast from the mid-Atlantic states through New England. These waves are likely to cause life-threatening surf and rip current conditions, and significant beach erosion. Please consult products from your local weather office.
