DISCUSSION AND OUTLOOK ---------------------- At 200 PM EDT (1800 UTC), the center of Tropical Storm Arthur was located near latitude 35.6 North, longitude 74.7 West. Arthur is moving toward the northeast near 16 mph (26 km/h). This general motion should continue today, followed by a turn toward the east on Tuesday. A slower southeast or south-southeast motion is forecast to begin Tuesday night and continue through Wednesday. On the forecast track, the center of Arthur will continue to move away from the North Carolina Outer Banks this afternoon. Arthur is then forecast to turn away from the east coast of the United States tonight and Tuesday. Maximum sustained winds are near 50 mph (85 km/h) with higher gusts. While some strengthening is forecast during the next 24 hours, Arthur is likely to lose its tropical characteristics late tonight or Tuesday. Tropical-storm-force winds extend outward up to 125 miles (205 km) from the center, primarily over water to the east of the center. A WeatherFlow observing site at Alligator River Bridge measured sustained winds of 39 mph (63 km/h) and a gust to 46 mph (74 km/h) earlier this afternoon. A wind gust to 42 mph (68 km/h) was recently reported at Oregon Inlet. The latest minimum central pressure estimated from reconnaissance aircraft data is 993 mb (29.32 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are expected within the Tropical Storm Warning area through this afternoon. RAINFALL: Arthur is expected to produce total rain accumulations of 1 to 3 inches over coastal North Carolina through this afternoon, with isolated maximum amounts of 5 inches. SURF: Swells generated by Arthur are affecting portions of the southeast U.S. coast and are expected to spread northward along the U.S. mid-Atlantic coast during the next day or so. These swells could cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
