DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 1100 AM AST (1500 UTC), the center of Post-Tropical Cyclone Hermine was located near latitude 37.2 North, longitude 69.6 West. The post-tropical cyclone is moving toward the east-northeast near 10 mph (17 km/h). A turn toward the north with a decrease in forward speed is expected later today, followed by a slow north-northwestward motion through Monday. On the forecast track, the center of Hermine will meander slowly offshore of the mid-Atlantic coast for the next couple of days. Maximum sustained winds have increased to near 70 mph (110 km/h) with higher gusts. Hermine is expected to be at or near hurricane strength during the next 48 hours. Tropical-storm-force winds extend outward up to 205 miles (335 km) from the center. The minimum central pressure estimated from Air Force reconnaissance aircraft observations is 999 mb (29.50 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions will spread northward within the warning area along the Atlantic coast through Monday. Tropical storm conditions are possible in the watch area by Monday. 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. There is a danger of life-threatening inundation within the next 36 hours from Cape Charles, Virginia, to Sandy Hook, New Jersey. Persons within these areas should take all necessary actions to protect life and property from rising water. Promptly follow all instructions, including evacuation orders, from local officials. There is also the possibility of life-threatening inundation during the next 48 hours at many coastal locations between Sandy Hook, New Jersey, and Bridgeport, Connecticut, including Long Island. For a depiction of areas at risk, please see the Prototype Storm Surge Watch/Warning graphic, which displays areas that would qualify for inclusion under a storm surge watch or warning currently under development by the National Weather Service and planned for operational use in 2017. The Prototype Graphic is available at www.hurricanes.gov/graphics_at4.shtml?wsurge The water could reach the following heights above ground if the peak surge occurs at the time of high tide... North Carolina sounds and northern Outer Banks...1 to 2 feet Cape Charles to Chincoteague, VA...2 to 4 feet Chincoteague, VA to Atlantic City, NJ...3 to 5 feet Atlantic City to Sandy Hook, NJ...2 to 4 feet Sandy Hook, NJ to Bridgeport, CT including Long Island...1 to 3 feet RAINFALL: Heavy rainfall associated with Hermine will remain offshore through Monday/Labor Day. Hermine will produce rainfall amounts of 1 to 2 inches over southern New England from Long Island to eastern Massachusetts, and additional rainfall of one inch or less along the coastline of the mid-Atlantic states. SURF: Large waves generated by Hermine will affect the U.S. east coast from the mid-Atlantic states and expand northward along the coast of southern New England through Monday. 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. NEXT ADVISORY ------------- Next intermediate advisory at 200 PM AST. Next complete advisory at 500 PM AST. $$ Forecaster Pasch/Roberts
