The National Hurricane Center (NHC) is monitoring two areas to watch for tropical development behind Hurricane Erin as the Atlantic Ocean's Main Development Region roars to life.

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.

Forecasters are monitoring two other tropical systems in the Atlantic Ocean on Aug. 19 as the heart of the 2025 hurricane season approaches.

Erin developed in the eastern Atlantic, moving westward from the Cabo Verde Islands at about 20 mph (32 km/h). Infrared sensors on NOAA's GOES-19 satellite reveal colder cloud tops and deep convection near the center — signs of a strengthening system feeding on warm ocean waters.

Hurricane Erin, which started as a tropical storm west of the Cabo Verde Islands, is making its way towards the east coast — although, its core is not forecast to go over land.

Hurricane watchers are eying systems in the Atlantic basin. One has a medium chance of developing later this week.
