Hurricane Erin strengthened into a fearsome Category 5 hurricane with sustained winds of 160 mph for much of the day on Aug. 16 as it traveled west just north of the Virgin Islands, according to the National Hurricane Center.

Hurricane Erin could 'at least double or triple in size' next week and the track has shifted south, but remains likely to turn away from the East Coast.

Erin has exploded into a Category 5 hurricane in Atlantic waters just north of the Caribbean, according to the National Hurricane Center.
