The National Hurricane Center is also watching two tropical disturbances to the east of Erin that could develop into named cyclones. With thousands of miles of warm ocean water, hurricanes known as Cape Verde storms are some of the most dangerous that threaten North America.

Outer bands from Hurricane Erin are expected to bring worsening conditions to the coast of North Carolina by this evening, according to the latest advisory from the National Hurricane Center. The Category 2 storm is continuing to move north-northwest and the center was located about 444 miles east of Daytona Beach at 8 a.m.

The storm, off North Carolina, was generating life-threatening surf and rip currents and causing beach closures along the East Coast.
