DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 500 AM AST (0900 UTC), the center of Post-Tropical Cyclone Hermine was located near latitude 37.7 North, longitude 68.3 West. The post-tropical cyclone is drifting toward the north near 3 mph (6 km/h). A gradual turn toward the north-northwest and northwest is expected to occur this afternoon and tonight. A northeastward motion is expected to begin by Tuesday night. 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 near hurricane strength through tonight. Gradual weakening is forecast to begin by Tuesday morning. Tropical-storm-force winds extend outward up to 230 miles (370 km) from the center. A ship located about 180 miles north of the center recently reported a sustained wind of 52 mph (83 km/h). The estimated minimum central pressure is 997 mb (29.44 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are expected to begin over portions of the warning area by this afternoon. 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: 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 tonight. 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.
