More than 50,000 utility customers were without power in Puerto Rico as the hurricane battered the Caribbean, bringing heavy rain, powerful wind and sizable waves to Puerto Rico and the Virgin Island...

Hurricane Erin was a Category 4 storm again Monday morning and is expected to grow even larger and stronger, according to the latest advisory from the National Hurricane Center.

The hurricane's outer rain bands have started to affect the Bahamas, the US National Hurricane Center (NHC) said.

A stronger and bigger Hurricane Erin pelted parts of the Caribbean and was forecast to create dangerous surf and rip currents along the U.S. East Coast this week.

Hurricane Erin is heading for the United States and so, too, could some massive waves, reaching more than 100 feet in height.

Even when they don't brush the coast or make landfall, such storms can be deadly and cause millions of dollars of damage.
