..TROPICAL WEATHER OUTLOOK SEPT. 15, 2023..

 

Storm Investigation 97L has a 90–90% formation chance and will more than likely be the next hurricane in the Atlantic. As it is, this storm system is scheduled to recurve over the North Atlantic and is not a threat to the U.S. mainland. 

The other storm investigation behind 97L presently has a 0–20% chance of formation. I will monitor this system since it could track further west and maybe into the eastern Caribbean.

Refer to the National Hurricane Center for the latest updates.
