Current Tropical Cyclones

There are no active tropical cyclones


For the North Atlantic…Caribbean Sea and the Gulf of Mexico:

Special Tropical Weather Outlook issued to discuss the potential for
subtropical development over the northwest Atlantic.

Northwestern Atlantic:

A non-tropical low pressure system (being referred to as Invest 90L) is centered over the northwestern Atlantic Ocean about 300 miles north of Bermuda is producing storm-force winds.

Although the cyclone is producing some thunderstorm activity near the center, it is embedded in a cold air mass with nearby frontal boundaries.

The low is expected to move northeastward today and northward tonight, bringing the system over much colder waters and across Atlantic Canada by early Tuesday. Therefore, it is unlikely that the low will transition to a subtropical or tropical cyclone.

Nevertheless, the system is expected to remain a strong non-tropical low during the next day or so.

No additional Special Tropical Weather Outlooks are scheduled for
this system. Regularly scheduled Tropical Weather Outlooks will
resume on May 15, 2023, while Special Tropical Weather Outlooks will
be issued as necessary during the off-season.

* Formation chance through 48 hours…low…near 0 percent.
* Formation chance through 5 days…low…near 0 percent.
