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

A non-tropical low pressure system is located over the central

opportunity to become a subtropical cyclone over the next 24 hours
before it becomes absorbed by a larger extratropical cyclone. The
next Special Tropical Weather Outlook will be issued by 2 PM EDT
Wednesday.  For additional information on this system, please
see High Seas Forecasts issued by the National Weather Service.
* Formation chance through 48 hours...low...30 percent

I have noticed more convection (thunderstorms) near the center of circulation.  This system could become a sub-tropical system before merging with an extra-tropical system.  Only a threat to shipping!
