Where are Helene and Isaac headed in the Atlantic?

• Sep 9, 2018 at 6:00 PM

Two new tropical storms have emerged in the eastern Atlantic Ocean and one could threaten some of the Caribbean Islands this week.

Tropical Storm Isaac and Tropical Storm Helene have joined Florence in the Atlantic Basin.

Helene, which is located off the west coast of Africa, has brought tropical-storm-force conditions to the Cabo Verde Islands over the weekend.

Farther west, Isaac will track toward the Lesser Antilles this week.

“There is a growing consensus that this system could threaten the Lesser Antilles during the middle or latter part of the week,” AccuWeather Hurricane Expert Dan Kottlowski said.

Environmental conditions across the Atlantic will be favorable for strengthening as it tracks toward the islands.

“There is a significant chance this storm may become a hurricane along the way,” AccuWeather Senior Meteorologist Alex Sosnowski added.

Regardless of strength, seas will become rough and dangerous for bathers and boaters along the east-facing portions of the islands as early as Wednesday.

Rain and wind would also increase during the second half of the week on the projected path of the tropical storm.

The current track of Isaac will take it south of the areas that bore the brunt of Irma and Maria's wrath last year.

"All interests in the Lesser Antilles should monitor the progress of this system closely," AccuWeather Senior Meteorologist Mike Doll said.

Now is the time for people on the islands to review or formulate a plan of action.

Cruise ships may have to alter their itinerary due to the storm.

People elsewhere in the Caribbean, including Puerto Rico, Hispaniola, Cuba, Jamaica and the Bahamas, and also in the United States should stay aware of the system's track beyond the Lesser Antilles.

Helene passed near the southernmost Cabo Verde Islands, bringing heavy rain, gusty winds and rough seas.

After moving on a westerly path over or very near to the Cabo Verde Islands this weekend, Kottlowski expects Helene to move more toward the northwest over the open waters of the central Atlantic through the week, posing no direct threat to land.
