For a depiction of areas at risk, please see the National Weather Service Storm Surge Watch/Warning Graphic, available at hurricanes.gov. This is a life-threatening situation. Persons located within these areas should take all necessary actions to protect life and property from rising water and the potential for other dangerous conditions. Promptly follow evacuation and other instructions from local officials. A Hurricane Warning means that hurricane conditions are expected somewhere within the warning area. A warning is typically issued 36 hours before the anticipated first occurrence of tropical-storm- force winds, conditions that make outside preparations difficult or dangerous. 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 within 36 hours. A Storm Surge Watch means there is a possibility of life- threatening inundation, from rising water moving inland from the coastline, in the indicated locations during the next 48 hours. For a depiction of areas at risk, please see the National Weather Service Storm Surge Watch/Warning Graphic, available at hurricanes.gov. Interests elsewhere in the northeastern U.S. should monitor the progress of Henri.

DISCUSSION AND OUTLOOK ---------------------- At 500 PM EDT (2100 UTC), the center of Hurricane Henri was located near latitude 36.3 North, longitude 71.4 West. Henri is moving toward the north-northeast near 18 mph (30 km/h) and this motion is expected to continue through tonight. A decrease in forward speed and a turn toward the north-northwest is expected on Sunday. On the forecast track, Henri is expected to make landfall on Long Island or in southern New England on Sunday. Maximum sustained winds are near 75 mph (120 km/h) with higher gusts. Strengthening is forecast through tonight. Although some weakening is expected prior to landfall on Sunday, Henri is forecast to be at or near hurricane strength when it reaches the coasts of Long Island and southern New England. Hurricane-force winds extend outward up to 45 miles (75 km) from the center and tropical-storm-force winds extend outward up to 150 miles (240 km). The estimated minimum central pressure is 991 mb (29.27 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Henri can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT3, WMO header WTNT43 KNHC and on the web at www.hurricanes.gov/graphics_at3.shtml?key_messages. STORM SURGE: The combination of a dangerous storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline. The water could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide... Flushing, NY to Chatham, MA including Narragansett Bay, Buzzards Bay, Vineyard Sound, and Nantucket Sound...3-5 ft North shore of Long Island from Flushing to Montauk Point, NY including Long Island Sound...3-5 ft South shore of Long Island from Mastic Beach to Montauk Point, NY...3-5 ft Chatham, MA to Sagamore Beach, MA including Cape Cod Bay...2-4 ft South shore of Long Island from East Rockaway Inlet to Mastic Beach, NY...2-4 ft Cape May, NJ to East Rockaway Inlet, NY...1-3 ft Sagamore Beach, MA to Merrimack River including Massachusetts Bay...1-3 ft The deepest water will occur along the immediate coast in areas of onshore winds, where the surge will be accompanied by large and dangerous waves. Surge-related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances. For information specific to your area, please see products issued by your local National Weather Service forecast office. WIND: Hurricane conditions are expected in the hurricane warning area late tonight or on Sunday, with tropical storm conditions expected by tonight. Tropical storm conditions are expected in the tropical storm warning area late tonight and Sunday. RAINFALL: Henri is expected to produce rainfall amounts of 3 to 6 inches over portions of Long Island, New England, southeast New York, and northern New Jersey Sunday into Monday, with isolated maximum totals near 10 inches. Heavy rainfall from Henri may result in considerable flash, urban, and small stream flooding, along with the potential for minor and moderate river flooding. TORNADOES: A tornado or two may occur Sunday over southern New England. SURF: Swells generated by Henri should continue to affect Bermuda during the next day or so. Swells are expected to increase across much of the east coast of the U.S. and Atlantic Canada today and Sunday. These swells could cause life-threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- Next intermediate advisory at 800 PM EDT. Next complete advisory at 1100 PM EDT. $$ Forecaster Cangialosi
