DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 1100 PM EDT (0300 UTC), the center of Post-Tropical Cyclone Hermine was located near latitude 36.5 North, longitude 72.1 West. The post-tropical cyclone is moving toward the east-northeast near 13 mph (20 km/h). A turn toward the northeast and the north with a decrease in forward speed are expected on Sunday, followed by a slow northward to 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 are near 70 mph (110 km/h) with higher gusts. Little change in strength is expected tonight. After that, the cyclone is expected to intensify to hurricane force Sunday and Sunday night. Hermine has a large wind field. Tropical-storm-force winds extend outward up to 205 miles (335 km) from the center. The estimated minimum central pressure is 998 mb (29.47 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions will continue to spread northward within the warning area along the Atlantic coast through Monday, and there may be multiple occurrences of tropical storm conditions along portions of the mid-Atlantic coast in the warning area during the next couple of days. 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 through tonight in the Hampton Roads area, and in the next 36 hours from Chincoteague, 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. 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...1 to 3 feet Hampton Roads area...2 to 4 feet Chincoteague, VA to Sandy Hook, NJ...3 to 5 feet Sandy Hook, NJ to Bridgeport, CT...2 to 4 feet RAINFALL: Heavy rainfall associated with Hermine will mainly remain offshore through Monday/Labor Day. However, isolated maximum rainfall amounts of 1 to 3 inches are still possible along the immediate coastline of the Mid-Atlantic and Northeast and up into southeast New England. 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.
