SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Tropical Storm Warning is in effect for... * North of Fenwick Island to Sagamore Beach * Delaware Bay south of Slaughter Beach * Block Island * Martha's Vineyard * Nantucket For storm information specific to your area, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office. DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 500 PM AST (2100 UTC), the center of Post-Tropical Cyclone Hermine was located near latitude 37.2 North, longitude 69.1 West. The post-tropical cyclone is moving toward the east-northeast near 5 mph (7 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 are near 70 mph (110 km/h) with higher gusts. Hermine should remain at or near hurricane strength for the next day or so, and begin to gradually weaken by Monday night. Tropical-storm-force winds extend outward up to 230 miles (370 km) from the center. The estimated minimum central pressure 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. 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 possibility of life-threatening inundation during the next 48 hours on the North Shore of Long Island east of Flushing and on the south shore of Long Island east of Rockaway Inlet. 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... Rehoboth Beach, DE to Montauk Point, NY including the North Shore of Long Island east of Flushing...1 to 3 feet RAINFALL: Heavy rainfall associated with Hermine will remain mainly offshore through Wednesday. Rainfall totals of 1 to 2 inches are possible across far southeastern Massachusetts, including Cape Cod and the offshore islands. 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.
