1. Life-threatening storm surge and dangerous winds will continue along portions of the North Carolina coast, portions of southeast Virginia and the southern Chesapeake Bay for the next several hours.

2. Areas of flash flooding, some of which may be significant and life-threatening, will continue into early afternoon across portions of northeastern North Carolina into far southeast Virginia.

3. Dangerous storm surge impacts are likely in portions of the Gulf of St. Lawrence, southwestern Newfoundland and eastern Nova Scotia this weekend. Hurricane-force winds are also likely in Nova Scotia, Prince Edward Island and possibly Newfoundland Saturday and Sunday. Refer to information from the Canadian Hurricane Centre for more information on these hazards.

A Storm Surge Warning means there is a danger of lifethreatening inundation, from rising water moving inland from the coastline, during the next 36 hours in the indicated locations. For a depiction of areas at risk, please see the National Weather Service Storm Surge Watch/Warning Graphic, available at hurricanes.gov. This is a lifethreatening situation. Persons located within these areas should take all necessary actions to protect life and property from rising water and the potential for other dangerous conditions. Promptly follow evacuation and other instructions from local officials.

A Hurricane Warning means that hurricane conditions are expected somewhere within the warning area. Preparations to protect life and property should be rushed to completion.

A Tropical Storm Warning means that tropical storm conditions are expected within the warning area within 36 hours.

A Hurricane Watch means that hurricane conditions are possible within the watch area.

A watch is typically issued 48 hours before the anticipated first occurrence of tropicalstormforce winds, conditions that make outside preparations difficult or dangerous.

A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, in this case within 36 hours. Interests elsewhere along the MidAtlantic and New England coasts of the United States should monitor the progress of Dorian. For storm information specific to your area in the United States, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office. For storm information specific to your area outside of the United States, please monitor products issued by your national meteorological service.

WIND: [TOP] Hurricane conditions should end along portions of the North Carolina coast during the next few hours. Tropical storm conditions should continue on the southeastern coast of Virginia for the next several hours, and are expected to spread across other portions of the the Mid-Atlantic states later today. Tropical storm conditions are also expected in the warning area over portions of extreme southeastern Massachusetts tonight or early Saturday, and in the warning area in Maine Saturday afternoon

Hurricane conditions are possible in Nova Scotia and Prince Edward Island Saturday, and tropical storm conditions are possible over other portions of the Canadian Maritime and Atlantic areas Saturday and Saturday night.

STORM SURGE: [TOP] 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...

Salter Path 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.

Storm Surge is likely in the Gulf of St. Lawrence, the Southwest Coast of Newfoundland, and Eastern Nova Scotia.

RAINFALL: [TOP] Dorian is expected to produce the following rainfall totals through Saturday:

Northeastern North Carolina into far southeast Virginia...Additional 1 to 4 inches, isolated storm totals 10 inches.

Extreme Southeastern New England...2 to 4 inches.

Nova Scotia and Prince Edward Island...3 to 5 inches.

Newfoundland...1 to 2 inches

This rainfall may cause life-threatening flash floods

SURF: [TOP] Large swells will affect much of the southeastern United States coast from northern Florida through North Carolina during the next couple of days. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.

At 1100 AM EDT (1500 UTC), the center of Hurricane Dorian was located near latitude 35.7 North, longitude 74.8 West. Dorian is moving toward the northeast near 17 mph (28 km/h) and this general motion with an increase in forward speed is expected through Saturday night. On the forecast track, the center of Dorian will move away from the coast of North Carolina during the next several hours. The center should move to the southeast of extreme southeastern New England tonight and Saturday morning, and then across Nova Scotia late Saturday or Saturday night.

Maximum sustained winds are near 90 mph (150 km/h) with higher gusts. Slow weakening is expected through Saturday. After that, Dorian is forecast to become a post-tropical cyclone with hurricane-force winds by Saturday night as it approaches Nova Scotia.

Hurricane-force winds extend outward up to 45 miles (75 km) from the center and tropical-storm-force winds extend outward up to 220 miles (350 km). About an hour ago, a Weatherflow station at Avon Sound, North Carolina reported a sustained wind of 83 mph (134 km/h) and a wind gust of 98 mph (158 km/h).

The minimum central pressure based on Air Force Reserve Hurricane Hunter data and surface observations is 957 mb (28.26 inches).

The eye of Dorian made landfall over Cape Hatteras, North Carolina, at about 1235 UTC and then moved quickly northeastward into the Atlantic. A combination of surface observations and Air Force Reserve Hurricane Hunter aircraft data indicate that the maximum winds are near 80 kt and the central pressure is near 957 mb. The hurricane remains well-organized in satellite imagery, with the 30 n mi wide eye surrounded by cold convective banding.

The initial motion is now 045/15. Dorian should accelerate northeastward during the next 24-36 h as a mid- to upper-level trough, currently over the U.S. Great Lakes, approaches the system and accelerates the steering flow. The track guidance remains tightly clustered, and the new track forecast is changed little in either direction or speed from the previous forecast. The new forecast calls for Dorian to move away from the North Carolina coast today, pass well southeast of southern New England tonight and Saturday, and then move over Nova Scotia Saturday or Saturday night. A continued northeastward motion is then expected to bring the cyclone across Newfoundland into the far north Atlantic.

Dorian is expected to slowly weaken due to increased shear and entrainment of drier air during the next 24 h or so. After that time, the hurricane is expected to undergo extratropical transition and become a large and powerful post-tropical low. It is unclear whether the transition will be complete before Dorian reaches Nova Scotia. However, whether Dorian is a hurricane or a hurricane-force extratropical low, it is expected to bring strong winds, storm surge, and heavy rains to portions of Nova Scotia and Newfoundland. The new NHC intensity forecast is little changed from the previous forecast, and it follows the trend of the intensity guidance.
