TAMPA, Fla. (WFLA) — The National Hurricane Center is watching two tropical waves in the Atlantic.

A disturbance near the Leeward Islands has a 60% chance of development over the next two days and a 70% chance of development over the next week. It became slightly less organized overnight, according to NHC forecasters.

The system is producing a small area of gale-force winds to the east of the center, according to NHC. Forecasters believe conditions are “marginally favorable” for development over the next few days. The NHC said a tropical depression will likely form early this week.

Meteorologists are also watching a tropical wave just off the U.S. mid-Atlantic coast. Forecasters say it is not likely a tropical cyclone will develop as the system merges with a frontal boundary.

The tropical wave has a 10% chance of development over the next two days.

Max Defender 8 meteorologist Leigh Spann said neither tropical wave should have much of an impact on the U.S. Both storms will likely stay in open water.
