Two more tropical systems trail Hurricane Erin, which is following a projected course that brushes past the East Coast without making landfall.

Hundreds of thousands of beachgoing tourists were keeping a watchful eye on massive Hurricane Erin on Tuesday, Aug. 19, as large waves and rough surf driven by the powerful storm were taking aim at the Atlantic Coast from Central Florida to Canada.

By Tuesday morning, Erin had lost some strength from previous days and dropped to a Category 2 hurricane with maximum sustained winds of 110 mph (175 kph), the National Hurricane Center in Miami said.

Hurricane Erin is moving east of the U.S. coast and will bring strong waves and rip currents to Florida's east coast – and it comes as the National Hurricane Center is eyeing two more tropical waves in the Atlantic.
