The hurricane is moving northeast at 20 mph, with maximum sustained winds of 100 mph.

“… the center of Erin will move over the western Atlantic between the U.S. east coast and Bermuda through early Friday, and then pass south of Atlantic Canada Friday and Saturday”, forecasters wrote about the hurricane. “Gradual weakening is forecast during the next couple of days.” They also said “Erin is expected to become post-tropical on Saturday.”

Changes with this advisory

The Tropical Storm Warning from Duck, North Carolina to Chincoteague, Virginia has been discontinued.

Watches and warnings currently in effect

• Storm Surge Warning for Cape Lookout to Duck, North Carolina

• Tropical Storm Warning for Bermuda

Meaning of the different watches and warnings

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

A Storm Surge Warning means there is a danger of life-threatening inundation, from rising water moving inland from the coastline, 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 life-threatening 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.

Interests in Atlantic Canada should monitor the progress of Erin and refer to local watches and warnings issued by Environment Canada.

Hazards affecting land

Wind. Tropical storm conditions are expected on Bermuda through early Friday. Wind gusts to tropical storm force are likely through early Friday along the mid-Atlantic and southern New England coast. Gusts to gale force are possible along portions of the coast of Nova Scotia on Friday and the Avalon Peninsula of Newfoundland on Saturday.

Surf. Swells generated by Erin will affect the Bahamas, Bermuda, the east coast of the United States, and Atlantic Canada during the next several days. These rough ocean conditions are expected to cause life-threatening surf and rip currents.

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 Lookout to Duck, North Carolina…2 to 4 ft

The deepest water will occur along the immediate coast where the surge will be accompanied by large and dangerous waves. Surge-related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances.
