Tropical Update from the National Hurricane Center – 10:00 p.m. – Thursday, September 5th
At 10:00 p.m. CDT, the eye of Hurricane Dorian was located near latitude 33.8 North, longitude 77.4 West. Dorian is moving toward the northeast near 13 mph, and this general motion is expected to continue with an increase in forward speed through Saturday. On the forecast track, the center of Dorian will move near or over the coast of North Carolina tonight and Friday. The center should move to the southeast of extreme southeastern New England Friday night and Saturday morning, and approach Nova Scotia later Saturday or Saturday night.
Maximum sustained winds are near 100 mph with higher gusts. Slow weakening is expected during the next few days. However, Dorian is expected to remain a powerful hurricane as the center moves near the coasts of South and North Carolina. Dorian is forecast to become a hurricane-force post-tropical cyclone by Saturday night as it approaches Nova Scotia.
Hurricane-force winds extend outward up to 60 miles from the center and tropical-storm-force winds extend outward up to 220 miles. A Weatherflow station located Federal Point, North Carolina, recently reported a sustained wind of 61 mph and a gust to 75 mph. The Johnny Mercer Pier NOAA-NOS station located at Wrightsville Beach, North Carolina, recently measured a sustained wind of 52 mph and a gust of 63 mph.
The minimum central pressure is estimated to be 958 mb based on a recent report of 958.9 mb from Frying Pan Shoals buoy located in Dorian’s eye.
HAZARDS AFFECTING LAND
WIND: Hurricane conditions are spreading along portions of the North Carolina coast. Tropical storm conditions are still affecting the northern portion of the South Carolina coast.
Tropical storm conditions are expected in the Tropical Storm Warning area in the Mid-Atlantic states by Friday and over portions of extreme southeastern Massachusetts by late Friday or early Saturday.
STORM SURGE: The combination of a dangerous 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…
- Cape Fear to Duck NC, including Pamlico and Albemarle
- Sounds and the Neuse and Pamlico Rivers…4 to 7 ft
- Duck NC to Poquoson VA, including Hampton Roads…2 to 4 ft
Water levels could begin to rise well in advance of the arrival of strong winds. The surge will be accompanied by large and destructive waves. Surge-related flooding depends on the how close the center of Dorian comes to the coast, 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.
RAINFALL: Dorian is expected to produce the following rainfall totals through Friday Night:
- South Carolina…Additional amounts up to a half inch, isolated storm totals of 12 inches.
- Eastern North Carolina…Additional 3 to 8 inches, isolated storm totals of 15 inches.
- Far southeast Virginia…3 to 8 inches.
- Extreme Southeastern New England…2 to 4 inches.
- This rainfall may cause life-threatening flash floods.
SURF: Large swells will affect the northwestern Bahamas, and the entire southeastern United States coast from Florida through North Carolina during the next few days. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
TORNADOES: Tornadoes are possible through early Friday across eastern North Carolina into southeast Virginia.
