Hurricane Erin has re-intensified into a category 4 major hurricane Sunday evening. Life threating surf and rip currents are likely across the East coast of the United States this week, as Hurricane Erin continues grow.

The storm will remain a major hurricane through the middle of the week, according to the National Hurricane Center.

While Erin is expected to take a northward turn in the Atlantic, a new system off the coast of Africa has the National Hurricane Center's attention.

Hurricane Erin weakened to a Category 3 storm with maximum sustained winds of 125 mph as its outer bands pounded the Virgin Islands and Puerto Rico with gusty winds and heavy rains early Sunday.

Tropical Storm Erin is likely to become Hurricane Erin shortly. It's now tracking over ocean water that's in the low 80s, and the dry and dusty air that has had a stranglehold on the circulation is dissipating.
