* Formation chance through 5 days...high...90 percent.



2. Eastern Tropical Atlantic:

A tropical wave is forecast to move off the west coast of Africa on

Thursday. Environmental conditions are forecast to be conducive for

at least gradual development of the system for a couple days

thereafter while the system moves slowly northward between west

Africa and the Cabo Verde Islands through the end of the week.

* Formation chance through 48 hours...low...near 0 percent.

* Formation chance through 5 days...medium...40 percent.
