DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 500 AM EDT (0900 UTC), the center of Tropical Storm Hermine was located near latitude 35.4 North, longitude 76.5 West. Hermine is moving toward the east-northeast near 21 mph (33 km/h), and this general motion with a decrease in forward speed is forecast to continue today. A gradual turn toward the north is expected on Sunday. On the forecast track, the center of Hermine will emerge over the Atlantic later today. Maximum sustained winds remain near 60 mph (95 km/h) with higher gusts. Strengthening is forecast after the center moves over water, and Hermine could be near hurricane intensity by Sunday. Tropical-storm-force winds extend outward up to 185 miles (295 km) mainly to the south and east of the center. The estimated minimum central pressure is 997 mb (29.44 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions will continue to spread northward within the warning area along the Atlantic coast through Sunday. Tropical storm conditions are possible in the watch area by late Sunday or Sunday night. 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. There is a danger of life-threatening inundation during the next 24 hours in the Hampton Roads area. Persons within this area 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 most coastal locations between the North Carolina/Virginia border 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 coast...1 to 3 feet Hampton Roads area...3 to 5 feet Elsewhere from the NC/VA border to Bridgeport, CT...2 to 4 feet RAINFALL: Hermine is expected to produce total rainfall accumulations of 4 to 7 inches over far southeastern Virginia and the Atlantic coastal portion of Maryland through Monday morning. Hermine is expected to produce total rainfall accumulations of 1 to 4 inches over southern Delaware, southern and eastern New Jersey, and Long Island through Monday morning. Moisture wrapping around Hermine and trailing back to the south will produce an additional 1 to 3 inches or rain over parts of North Carolina and northern Florida. This rainfall may contribute to flooding in some areas. NEXT ADVISORY ------------- Next intermediate advisory at 800 AM EDT. Next complete advisory at 1100 AM EDT. $$ Forecaster Avila
