System type: Post-tropical cyclone

System name: Erin

At 4 p.m. Friday, the National Hurricane Center released the final advisory for the post-tropical cyclone system. Erin became a post-tropical cyclone with sustained winds of 90 mph after intensifying from a Category 1 hurricane. Post Tropical Cyclone Erin is in the Atlantic Ocean, 605 miles north-northeast of Bermuda and 375 miles south-southeast of Halifax Nova Scotia. The system, with maximum sustained winds of 90 mph, is moving east-northeast at 33 mph.

“… the center of Erin will pass south of Atlantic Canada today and tonight, and then race across the north Atlantic waters”, forecasters wrote. They also said “Erin is likely to remain a large and powerful hurricane-force low pressure system through the weekend.”

Yesterday (Thursday)

The Category 2 hurricane named Erin developed into a Category 1 hurricane with winds of 90 mph. It was previously forecasted as a Category 2 hurricane but has since gained strength. A tropical storm warning has been issued by forecasters for Bermuda.

Hazards affecting land

Wind. Gale-force wind gusts are possible along portions of the coast of Nova Scotia today 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 few days. These rough ocean conditions are expected to cause life-threatening surf and rip currents.

Storm surge. Some coastal flooding is expected at times of high tide along portions of the U.S. Mid-Atlantic and New England coasts through tonight, making some roads impassable. See updates from your local National Weather Service office for details.
