National Hurricane Center in Miami, Florida, forecast on tropical activity: Where is Isaias?
According to the 8 a.m. Sunday, Oct. 11, 2026, tropical weather outlook from the National Hurricane Center in Miami, Florida, the weather prediction center was issuing advisories on Post-Tropical Cyclone Isaias, located near the border of Tennessee and Kentucky. In addition, there is a tropical disturbance in the Atlantic with a low chance of formation.
The NHC reports:
Eastern Tropical Atlantic (shown in yellow): An elongated area of low pressure centered a few hundred miles southwest of the Cabo Verde Islands is producing a large but disorganized area of showers and thunderstorms extending from these islands southward into the eastern Tropical Atlantic. Environmental conditions appear only marginally conducive for some development of this system over the next day or two before upper-level winds become too strong for development by midweek. Regardless of development, heavy rainfall will be possible during the next few days over portions of the Cabo Verde Islands as the system moves slowly northward to north-northwestward.
Formation chance through 7 days was low at 20 percent.Formation chance through 48 hours was low at 20 percent.
The graphic above automatically updates with the most recent location for any or all disturbances. The NHC also reported it is monitoring three tropical waves:
An eastern Atlantic tropical wave was along 29W, south of 19N, moving westward at 10-15 knots. A 1011 mb low pressure was analyzed along the wave and monsoon trough near 13N27W. The broad system was producing a large area of showers and thunderstorms, mainly from 06N to 17N and between 22W and 36W.Another eastern Atlantic tropical wave was along 38W, south of 19N, moving westward at 10-15 knots. Scattered moderate to isolated strong convection was observed from 08N to 17N and between 33W and 45W.A western Caribbean tropical wave was along 88W, south of 19N, moving westward at 10-15 knots. The wave continues to interact with an upper-level low over the NW Caribbean, and was supporting scattered moderate to isolated strong convection over much of the NW Caribbean.
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.

What are the 2026 Atlantic hurricane season names? Did your name make the hurricane season names list?
Since 1953, the National Hurricane Center has released a list of names in alphabetical order for Atlantic tropical storms before each season begins, which it recycles every six years. It retires names of storms that are excessively deadly or costly, if it would be insensitive or inappropriate to use them again. These are the 2026 Atlantic tropical cyclone names:
Arthur, which formed as a tropical storm June 17, 2026Bertha, which formed as a tropical storm July 20, 2026Cristobal, which formed as a tropical storm Aug. 12, 2026Dolly, which formed as a tropical storm Aug. 27, 2026Edouard, which formed as a tropical storm Sept. 1, 2026Fay, which formed as a tropical storm Sept. 20, Sept. 23, and Sept. 28Gonzalo, which formed as a tropical storm Sept. 24Hanna, which formed as a tropical storm Sept. 28Isaias, which formed as a tropical storm Oct. 7 and hours later strengthened into a hurricane, making landfall in Destin, Florida, on Oct. 9JosephineKyleLeahMarcoNanaOmarPauletteReneSallyTeddyVickyWilfred
