Tracking the forecast for potential tropical cyclone nine over the next five days.

Here we go again.

Fresh from the first hurricane in the 2020 Atlantic season, another tropical storm is likely to form this week in the central Atlantic Ocean. This storm, currently located over the central Atlantic, has been designated as a potential tropical cyclone by the National Hurricane Center.

A potential tropical cyclone means, in part, that the National Hurricane Center believes the storm has a high probability of becoming a tropical cyclone and forecasts cones, tropical alerts, and more before a tropical cyclone officially develops.

The next storm on the Atlantic hurricane list is Isaias. It would become the ninth named storm of a 2020 Atlantic hurricane season already hyperactive to date.

If Isaias really develops, it would become the first named I-registered storm. The current record for the storm for the ninth season name is Irene, who formed on August 7, 2005.

If you’re wondering how exactly to pronounce Isaiah, here is a detailed guide on how to say it correctly (along with all the other 2020 Atlantic storms.

As of Tuesday, the tropical wave was about 500 miles east of the Windward Islands.

Spaghetti models, a set of computer forecast models overlaid on a map, show that the storm is likely to gradually turn north as it moves west across the Atlantic.

Spaghetti models show a general runway from west to northwest before potentially approaching the southeastern U.S.

The first impacts of the system on land could be tonight in the Leeward Islands, where heavy rains are expected. Flash floods and life-threatening landslides are possible.

There are tropical storm warnings across much of the Caribbean, including the islands of Dominica, Puerto Rico, the US Virgin Islands, and the United Kingdom, Antigua and Barbuda, Montserrat, Guadalupe, Saint Martin, Anguilla, and Saint Kitts and Nevis , and the Dominican Republic.

Heavy rains and strong gusts of wind will spread to the Virgin Islands and Puerto Rico from Wednesday to Thursday night.

Most computer-based forecasting models show that the storm is slowly strengthening into a tropical storm this week, although the long-term path is still highly uncertain.
