Hurricane Erin was the fifth named storm of the season. As of Thursday afternoon, the storm is still a Category 2 hurricane with maximum sustained wind speeds of 100 mph. Its path is taking it away from the U.S., after, for the past few days, the storm has skirted the East Coast and caused dangerous waves and life-threatening rip currents.

With thousands of miles of ocean water above the 80-degree Fahrenheit (27-degree Celsius) temperature needed to fuel hurricanes, Cape Verde storms are some of the most dangerous that threaten North America. About 85% of all major hurricanes — Category 3 and higher — start out there, according to the National Hurricane Center.
