Hurricane Erin is a huge Category 4 storm and is expected to both grow larger and stronger today as it moves toward the west-northwest. The center of the storm is expected to remain offshore as it moves between the U.S. and Bermuda.

Forecasts nudge Erin's likely path to the west, increasing the risks at U.S. beaches. Tropical storm conditions are expected in North Carolina's Outer Banks starting late Wednesday.

The first area has been under the eyes of the National Hurricane Center for a few days as it emerged off Africa’s west coast.

A westward-moving tropical wave could produce an area of low pressure in the tropical Atlantic late in the week of Aug. 18, the hurricane center said on Aug. 16. The center shows a 20% chance of storm formation over the next week.

The National Hurricane Center is tracking two systems in the Atlantic basin, including a new one moving into the Gulf.

Forecasters say the monster storm will turn away from the eastern U.S. and won’t make landfall. But they predict it will churn up dangerous rip currents.

A potential tropical storm could develop later this week in the same region that produced Hurricane Erin. The season's sixth tropical storm would be named Fernand.

The National Hurricane Center is watching two areas of interest in the Atlantic behind Erin. Here's the latest on what may happen next.

Forecasters are tracking three systems in the Atlantic basin, including one with a medium chance of becoming a tropical depression later this week.

An Atlantic disturbance now has a 50 percent chance of cyclone formation, according to the National Hurricane Center.
