DISCUSSION AND OUTLOOK ---------------------- At 800 PM EDT (0000 UTC), the center of Tropical Storm Ophelia was located near latitude 37.0 North, longitude 77.6 West. Ophelia is moving toward the north near 9 mph (15 km/h). A gradual turn toward the northeast is expected by tomorrow. On the forecast track, the center of Ophelia is expected to continue moving over southeastern Virginia through tonight, and then over the Delmarva Peninsula by tomorrow. Maximum sustained winds have decreased to near 35 mph (55 km/h) with higher gusts. Additional weakening is expected, and Ophelia is likely to become a post-tropical cyclone tomorrow. The estimated minimum central pressure is 1000 mb (29.53 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Ophelia can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT1, WMO header WTNT41 KNHC, and on the web at hurricanes.gov/text/MIATCDAT1.shtml STORM SURGE: The combination of storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline. The water could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide... Hatteras Inlet, NC to Manasquan Inlet, NJ...1-3 ft Chesapeake Bay and Tidal Rivers...1-3 ft Delaware Bay...1-3 ft Beaufort Inlet, NC to Hatteras Inlet, NC...1-2 ft Neuse, Bay, Pamlico, and Pungo Rivers...1-2 ft Albemarle and Pamlico Sound...1-2 ft The deepest water will occur along the immediate coast in areas of onshore winds, where the surge will be accompanied by dangerous waves. Surge-related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances. For information specific to your area, please see products issued by your local National Weather Service forecast office. WIND: Gusty winds to tropical storm force are still possible near the coasts of North Carolina and Virginia during the next few hours. RAINFALL: Ophelia is expected to produce the following additional rainfall through Sunday night: Portions of the Mid-Atlantic from north central North Carolina through New Jersey...1 to 3 inches with isolated higher totals up to 5 inches. Across southeastern New York through southern New England...1 to 3 inches. This rainfall may produce locally considerable flash, urban, and small stream flooding impacts, particularly across the Mid Atlantic region from North Carolina to New Jersey. Isolated river flooding is possible in areas of heavier rainfall. SURF: Swells generated by Ophelia will continue to affect much of the east coast of the United States through the weekend. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. TORNADOES: A tornado or two may occur through tonight across parts of the Mid-Atlantic Coast. NEXT ADVISORY ------------- Next complete advisory at 1100 PM EDT. $$ Forecaster Berg |
