Lorenzo Weakens as a New Tropical Wave Emerges off Africa

Lorenzo is currently the only active named storm in the Atlantic. The tropical storm is located in the central Atlantic and poses no threat to land.

Lorenzo should dissipate by the end of this week.

Meanwhile, a new tropical wave has emerged off the coast of Africa.

While tropical development is not anticipated in the short-term, many weather models have this disturbance entering the central and west Caribbean over a week from now. That track would eventually take it into a favorable environment for organizing if it survives crossing the Main Development Region of the Atlantic.

This is reflected within the latest Tropical Cyclone Outlook, where the Climate Prediction Center has assigned the spot over a 40% chance of development between October 22nd/28th. It’s far too early to draw conclusions on the path it may take if it becomes our next named system.

If a named storm forms, the next name used will be Melissa.

Tropical Storm Lorenzo forms in Atlantic

Tropical Storm Lorenzo, the 12th named storm of the season, formed early Monday morning in the central Atlantic.

The good news is Lorenzo will move north, staying out to sea and far away from land thanks to a weakness in the subtropical ridge.

Tropical Storm Lorenzo will strengthen by early Thursday with 70 mph sustained winds forecast. From there, it will gradually weaken into this weekend as it curves NE south of the Azores.

Lorenzo is currently about 1,000 miles west of the Cabo Verde Islands with 45 mph sustained winds.

It is fighting off some wind shear, which is limiting strengthening, but shear will lessen and will open the door for Lorenzo to strengthen more on Wednesday-Thursday.

The storm is moving northwest at about 17 mph but is expected to gradually turn north on Tuesday then NE.

So far this season: 12 named storms, 4 hurricanes and 3 major hurricanes have formed.

The trend of storms taking a hard turn north and curving out to sea or remaining out to sea entirely has been notable.

Melissa is the next name in line on the 2025 season list followed by Nestor.
