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.

1. 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.

2. 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.
