There is a high chance for a tropical depression to form today or Sunday with Invest 90L just shy of reaching that status. Hurricane Hunters are set to fly into the area Saturday afternoon to get the latest data on this disturbance.

This broad low pressure system is 500 miles south-southeast of Bermuda and strong steering is still in place to guide the storm away from the U.S. with a north to northeast track.

Bermuda is just west of where models take Invest 90L in the next few days. Watches could be required for the island as the storm looks like it could make a close pass before curving more northeast.

Invest 90L could become Fernand as things are favorable for additional development in the coming days. 39+ mph winds are needed for it to become Tropical Storm Fernand.

The other disturbance, Invest 99L, is about 800 miles east of the Windward Islands. It only has a 20% chance to form as it moves west.

Locally heavy rain and gusty winds are possible for the islands Sunday into Monday as the disorganized area of storms moves through.

Erin is now a post-tropical cyclone, moving very quickly (forward at 33mph) away from the United States.

This is the last advisory for Erin. Its remnants may eventually become a player in Europe’s local forecast next week.

Meanwhile we are tracking two other disturbances in the Atlantic. Neither brings any immediate threat to Florida or the United States.

Invest 90L will likely become a named storm within the next day or so, and possibly a hurricane after that. Upper-level steering should pull this north and eventually recurve it away from the U.S. 

Residents of Bermuda should monitor the development of this system carefully.

Meanwhile, Invest 99L now has a 40% chance of formation as it approaches the Windward Islands early next week. While a short-lived tropical depression could form from this disturbance in the short-term, it could enter into a favorable environment for development late this weekend into the start of next week. 

The Windward islands will need to keep an eye on 99L over the next few days. 

The next name on our 2025 storm naming list is Fernand.
