It has entered a more supportive environment for development and will likely become a tropical storm by this weekend. Most model guidance has the system topping out as a tropical storm, but some models suggest it could make a run at hurricane strength early in the week ahead.

The next name on the 2025 hurricane season list is Fernand (pronounced fair-NAHN).

In terms of path, the majority of computer forecast models suggest this system will curl north, then northeast into the central Atlantic Ocean next week.

Though this system will not be a mainland U.S. threat, it will likely bring at least rainy weather to Bermuda as soon as Sunday night or Monday, depending on how soon it makes that northward turn.

Interests in Bermuda should monitor the progress of this system.

Eastern Area Of Interest

There is a tropical wave in the central tropical Atlantic between western Africa and the Lesser Antilles, which has been tagged Invest 99L by the National Hurricane Center.

The NHC says Invest 99L is moving into less favorable conditions through Saturday. Conditions could become slightly more supportive for development again late this weekend into early next week as the system approaches the Lesser Antilles around Tuesday.
