TAMPA, Fla. ( WFLA ) — The National Hurricane Center is tracking two tropical waves in the Atlantic, including one with a 70 percent chance of development.

The NHC said a tropical wave located several hundred miles southwest of the Cabo Verde Islands continues to produce disorganized shower and thunderstorm activity.

According to the NHC, a tropical depression or tropical storm will likely form this weekend several hundred miles east of the Windward Islands.

“The tropical wave in the eastern Atlantic Ocean should slowly organize, and it may become our next tropical depression or storm in the next seven days,” said meteorologist Leigh Spann with Nexstar’s WFLA. “It will battle the dust coming from the Sahara Desert that will limit its ability to get too strong. Most of the computer forecast models take the system west toward the Caribbean Sea.”

Another tropical wave located over the west-central Caribbean Sea is producing disorganized shower and thunderstorm activity while it moves rapidly westward at around 25 mph.
