A new system has emerged in the eastern tropical Atlantic, heading westward toward the Leeward Islands as Hurricane Erin continues to spin.

Hurricane Erin – an already powerful Category 4 storm in the Atlantic Ocean – is getting stronger and is expected to grow even larger, according to the National Hurricane Center.

The monster storm intensified to a Category 4 with 140 mph (225 kph) maximum sustained winds early Monday while it started to lash the Turks and Caicos Islands and the southeast Bahamas, according to the U.S. National Hurricane Center in Miami.

After a weekend of staggering strengthening, Hurricane Erin remained a major hurricane Monday on its path skirting away from the United States. And following behind in the Atlantic is another system the National Hurricane Center has given a medium chance of further development.

As Tropical Storm Erin moves through the Atlantic, New Yorkers may need to skip some beach days as there's some potential for dangerous rip currents.
