What To Know

In an early morning update on Tuesday, the NHC said a tropical wave, located "a few hundred miles" southeast of the Cabo Verde Islands was producing a "concentrated area of showers and thunderstorms."

"Environmental conditions appear generally favorable for additional development over the next couple of days as the system moves westward at around 15 mph," the agency said. "Towards the end of this week, this system could encounter a less favorable environment, limiting its development chances after that time."

The NHC gave the disturbance a "low" 30 percent chance of cyclone development through both 48 hours and seven days.
