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

The National Hurricane Center is issuing advisories on Tropical
Storm Nicholas, located over the western Gulf of Mexico.

A tropical wave has emerged off the west coast of Africa near
the coasts of Guinea and Sierra Leone.  Environmental conditions
are forecast to be conducive for gradual development of this
disturbance, and a tropical depression is likely to form by late
this week while the system moves westward at 10 to 15 mph across
the eastern tropical Atlantic Ocean.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 5 days...high...80 percent.

An area of low pressure is forecast to form by midweek a couple of
hundred miles north of the southeastern or central Bahamas as a
tropical wave interacts with an upper-level trough.  Some gradual
development of this system is possible thereafter, and a tropical
depression could form later this week while the system moves
north-northwestward or northward across the western Atlantic.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...medium...50 percent.
