Erin is a Category 3 hurricane, the National Hurricane Center said in its 5 p.m. ET update Sunday, with sustained winds of 125 mph, and tropical storm-force winds reaching out 205 miles. The storm is expected to continue to fluctuate in intensity and could double or even triple in size as it moves north and west,

Erin is the first hurricane to develop over the Atlantic this year, and meteorologists are closely tracking its path and forecast.

Regardless of Erin's track, rough surf and rip currents will pose a significant hazard to beaches throughout the Antilles, eastern U.S., Bermuda, and possibly Atlantic Canada as the hurricane both strengthens and grows in size over the next week.
