Forecasters are keeping an eye on tropical waves − what else is out in the Atlantic?
More than three months after the start of hurricane season, there is a disturbance churning in the tropics, but so far, chance for development is low to medium.
The Saturday, Sept. 13, 2025, tropical weather advisory from the National Hurricane Center in Miami, Florida, shows the tropical wave has a 0 percent chance of formation in the next two days and a 50 percent chance of formation within the next seven days, in the open Atlantic.
The hurricane center graphics and live weather radars below show what’s swirling in the tropics as well as the conditions for potential rain, flash flood and other warnings.
➤ 2025 Atlantic hurricane season predictions
Atlantic hurricane season is from June 1 to Nov. 30 every year, with the most activity between August and October. Should another weather system develop into a tropical storm, the system would be named Gabrielle, which is next on the list of the 2025 Atlantic hurricane season names (see below).
In addition, the hurricane center is tracking more tropical waves in the Caribbean. Each are moving west and do not pose a threat at this time.

National Hurricane Center in Miami, Florida, forecast on tropical activity: Is there a tropical storm or hurricane now?
According to the Saturday, Sept. 13, 2025, tropical outlook from the National Hurricane Center in Miami, Florida, a disturbance has a chance of formation in the next few days. The graphic above, however, automatically updates with the most recent location for all disturbances.
In the eastern and central tropical Atlantic, shown in orange in the graphic above:
A tropical wave located near the Cabo Verde Islands is producing limited shower and thunderstorm activity over the far eastern Atlantic. Dry and stable air will likely limit this system’s development over the next few days, but a tropical depression could form by the middle to latter part of next week while moving west-northwestward to northwestward at 10 to 15 mph over the central tropical Atlantic.
Formation chance through 48 hours is low, near 0 percent.
Formation chance through 7 days is medium, at 50 percent.
In addition to the tropical disturbance, the hurricane center is keeping an eye on these tropical waves:
The axis of an eastern Atlantic tropical wave is near 24W from 02N to 20N, moving westward at 10 to 15 knots. Rather limited scattered moderate convection is seen from 13N to 16N between 19W and 23W, and within 60 nm of 12N27W. Dry and stable air will likely limit this system’s development over the next few days, but a tropical depression could form by the middle to latter part of next week while it moves west-northwestward across the central tropical Atlantic. There is a medium chance for tropical development within the next 7 days.
The axis of a central Atlantic tropical wave is near 40W from 01N to 20N. It is moving westward around 10 knots. Scattered moderate convection is within 120 nm east of the wave from 14N to 16N.
The axis of a central Atlantic tropical wave is near 60W south of 19N, moving westward at about 10 knots. Scattered showers and isolated thunderstorms are from 10N to 16N between 55W and the wave, and also within 60 nm west of the wave from 15N to 17N.
A western Caribbean tropical wave has its axis near 86W south of 20N, moving westward at 10 knots. Scattered moderate to isolated strong convection is ahead of this wave confined to the Gulf of Honduras. Scattered showers and isolated thunderstorms are within 180 nm east of the wave south of 19N.

The Atlantic basin consists of the northern Atlantic, Caribbean Sea and Gulf of America. NOAA changed its naming convention for the Gulf of Mexico after the U.S. Geological Survey changed the name on U.S. maps per President Trump’s order.
