System type: Hurricane, Category 1

System name: Erin

At 1 a.m. Friday, the National Hurricane Center issued an advisory stating that Erin found new strength and had evolved from a Category 2 hurricane into a Category 1 hurricane with sustained winds of 90 mph. Category 1 Hurricane Erin is in the Atlantic Ocean, 400 miles north-northwest of Bermuda and 490 miles south-southwest of Halifax Nova Scotia. The hurricane, with maximum sustained winds of 90 mph, is moving northeast at 22 mph.

“… the center of Erin will move over the western Atlantic between New England and Bermuda through this morning, and then pass south of Atlantic Canada today and Saturday”, analysts explained about the hurricane. They also said “Gradual weakening is forecast during the next couple of days, but Erin is still expected to be producing hurricane-force winds when it becomes post-tropical on Saturday.”

Watches and warnings currently in effect

• 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.

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 for a few more hours. Wind gusts to tropical storm force are likely through this morning along the southern New England coast. Gusts to gale force 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 several days. These rough ocean conditions are expected to cause life-threatening surf and rip currents.
