According to the NHC, the disturbance has a 60% chance of development in the next two days and an 80% chance in the next seven days.

The wave is producing showers and thunderstorms several hundred miles west-southwest of the Cabo Verde Islands while slowly moving west-northwest at 5–10 mph.

FOX 13 meteorologists say a weaker system would likely track farther west while a quickly organizing tropical storm or hurricane would likely be steered north quickly.

Forecasters say it will eventually track into a more favorable environment with warmer sea surface temperatures as it nears the Leeward Islands.

“This is all seven to 10 days from now, so nothing to be concerned about,” Osterberg said.

The next name on our 2025 storm naming list is Gabrielle.
