After losing some intensity over the weekend, Erin strengthened back into a Category 4 storm with maximum sustained winds of 140 mph, according to an 11 a.m. ET advisory from the National Hurricane Center.

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 of 7 a.m. CDT Monday, the center of Category 4 Hurricane Erin was located about 115 miles north-northeast of Grand Turk Island, or 890 miles south-southeast of Cape Hatteras, N.C., and was tracking to the northwest at 13 mph.

Over the weekend, northern portions of the Leeward Islands, the Virgin Islands, and Puerto Rico are expected to receive tropical rain ranging from 2 to 4 inches, with isolated totals up to 6 inches. Flash flooding, landslides and mudslides will be the main concerns over the next several days.

Here is some of the projected computer models of Hurricane Erin's potential path as it treks across the Atlantic Ocean, and away from Florida and the United States. Here are some live views of Hurricane Erin from satellites in space.

A sprawling, powerful Hurricane Erin is churning toward the mid-Atlantic but is not to directly pound the U.S. coastline.  But that doesn’t mean it won’t have a major impact as forecasters are warning of rip currents and towering waves along the Eastern seaboard.

Hurricane Erin has intensified to a Category 4 storm affecting the Caribbean, impacting flights and cruise itineraries, with warnings issued for the Bahamas and Turks and Caicos, and it poses a significant coastal threat to the U.

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.

Hurricane Erin is forecast to remain well offshore but still bring hazardous currents and possible erosion like previous offshore hurricanes before it.

Hurricane Erin regained Category 4 strength Sunday night as its outer bands pounded the Virgin Islands and Puerto Rico with gusty winds and heavy rains.
