Hurricane forecasters are tracking two tropical waves in the Atlantic that could be the next areas of concern in the wake of Hurricane Erin. Here’s what the spaghetti models are showing.

A tropical storm warning is in effect for: Beaufort Inlet, North Carolina to Chincoteague, Virginia, including Pamlico and Albemarle sounds. A storm surge warning means there is a danger of life-threatening inundation, from rising water moving inland from the coastline, during the next 36 hours in the indicated locations.

The first Atlantic hurricane of the season is forecast to bring heavy rain and life-threatening surf and rip currents to the U.S. East Coast this week.

A 5 p.m. update listed the chances of the wave's further development at 60% over the next seven days. The wave is producing “disorganized showers and thunderstorms” and could form a tropical depression by the end of the week as it moves toward the Windward Islands on the eastern side of the Caribbean,

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.

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