Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 PM EDT Sun Sep 9 2018

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

The National Hurricane Center is issuing advisories on recently
upgraded Hurricane Florence, located over the west-central Atlantic
Ocean, on Tropical Storm Helene, located just southwest of the Cabo
Verde Islands, and on Tropical Storm Isaac, located over the eastern
Atlantic.

The combination of an upper-level trough and a tropical wave over
the northwestern Caribbean Sea is producing a large area of
disorganized showers and thunderstorms between Cuba and Honduras.
Upper-level winds could become somewhat more conducive for some
development when the system moves into the Gulf of Mexico in a
couple of days while the system moves slowly west-northwestward or
northwestward.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...20 percent.

A non-tropical area of low pressure is forecast to form in the
northeastern Atlantic Ocean several hundred miles west-southwest of
the Azores in two or three days.  Some slow tropical or subtropical
development is possible by the middle of the week while the low
moves southwestward.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...30 percent.
