The Brief

    • The next potential tropical threat appears focused on the Caribbean and Gulf of Mexico, where Hurricane Helene ultimately developed.
    • An area of low pressure is expected to develop in the Caribbean Sea over the next few days, and then move into the Gulf of Mexico.
    • It's too soon to know how much this new system will ultimately develop, but those along the U.S. Gulf Coast, including Florida, should pay attention, NHC said.
    • Florida is still cleaning up from Helene, which hit Florida's Big Bend region as a Category 4 hurricane.

As post-tropical storm Helene makes its way up the Midwest of the United States – and Florida continues to clean up from its impacts – Tropical Storm Joyce, Hurricane Isaac, and two other disturbances are being monitored in the Caribbean Sea, and the Atlantic Ocean.

Tropical Storm Joyce and Hurricane Isaac are not expected to have any impacts on Florida or the United States. However, a disturbance in the Caribbean and one in the Atlantic have medium and high chances of further development next week.

The next 2024 Atlantic storm names are Kirk, Leslie, Milton, and Nadine. Here is the latest that we know.

Disturbance 1 in the Eastern and Central Tropical Atlantic

The National Hurricane Center is monitoring an elongated area of low pressure in the central tropical Atlantic a couple of hundred miles west of the Cabo Verde Islands for potential development over the next week.

In its latest update, the NHC said this area of development is producing disorganized showers and thunderstorms, but has a high chance – 70% – of developing into a tropical depression early next week. The system is expected to continue to move west, and is then forecast to move into the eastern and tropical Atlantic.

Disturbance 2 in the Western Caribbean Sea and Gulf of Mexico

An area of low pressure is expected to form over the next couple of days in the Caribbean Sea, not far from where Helene ultimately developed, the National Hurricane Center said.

This system has a medium chance – 50% – of becoming a tropical depression next week, the NHC said. It is expected to move into the Gulf of Mexico later next week, where it could develop further.

Tropical Storm Joyce

Tropical Storm Joyce continued to move northwestward over the central Atlantic Ocean.

Tropical Storm Joyce was 1,120 miles east of the Northern Leeward Islands with sustained winds of 50 mph. It was moving NW at 10 mph. The minimum central pressure was 1004 mb, the NHC said in its latest advisory.

Joyce is expected to weaken Saturday night or on Sunday and could become a remnant low by Tuesday, the NHC said.

Hurricane Isaac

Hurricane Isaac remains a Category 2 hurricane with sustained winds of 105 mph. In its latest update, Isaac was 695 miles west of the Azores, and was moving ENE at 20 mph. The minimum central pressure was 968 mb.

Isaac is forecast to gradually weaken and could become a post-tropical cyclone on Monday.
