If it becomes a tropical storm, the next name on the list is Isaias.
But don't take any of that to the bank just yet.
That's because the system doesn't have a true center of circulation yet, which makes forecasting its path particularly challenging.
The long-term forecast showed the storm headed toward the southeastern US, though the hurricane center emphasized the system is still in the formative stage and accurately predicting its path was hard.
Forecasters say tropical storm watches or warnings could also be issued to portions of the islands later Tuesday and are asking those with interests in this area to continue monitoring the progress of this system.More news: Scientists revive 100 million-year-old microbes in a lab
The storm, which would be named Isaias if it reaches tropical storm strength, was expected to move through the Leeward Islands on Wednesday, and near or over the Virgin Islands and Puerto Rico on Wednesday night.
Gusty winds and heavy rain were spreading across some of those islands as of Wednesday morning, according to the hurricane center.
It's not officially a tropical storm, but the system's winds got a little stronger - up to 45 miles per hour now, and it could become Tropical Storm Isaias later today.
Tropical storm conditions are expected to reach the Leeward Islands on Wednesday and Puerto Rico on Wednesday afternoon through Thursday. The hurricane center said the strongest winds were located far north or its "center" position.
Forecasters issued tropical storm warnings for Puerto Rico, the British and U.S. Virgin Islands, Antigua, Barbuda, Dominica, Martinique, Montserrat, St. Kitts and Nevis, Guadeloupe, Martinique, St. Martin, St. Maarten, Saba, St. Eustatius and portions of the Dominican Republic.More news: ACC schedule includes Notre Dame, 10 conference games
The storm is expected to touch down in Puerto Rico on Wednesday.
While the system still does not have a well-defined center, "environmental conditions are expected to become somewhat more conducive for development, and a tropical depression or tropical storm is likely to form during the next couple of days while the system moves west-northwestward at 15 to 20 miles per hour and approaches the Leeward Islands", forecasters wrote.
The system will produce heavy rain and "potentially life-threatening flash floods and mudslides across the Leeward Islands, the Virgin Islands and Puerto Rico and the Dominican Republic", according to the NHC.
This will be hot on the heels of five other tropical storms that have set the same record this year for their corresponding letters: Cristobal, Edouard, Fay, Gonzalo and Hanna.More news: European Union to Limit Sale of ‘Sensitive’ Equipment to Hong Kong
