The National Hurricane Centre (NHC) in Miami is tracking two tropical waves that have formed in the Atlantic off the coast of Africa.

One of the systems has a 60 percent chance of developing into a tropical cyclone in the next five days and the other has been given a 40 percent chance.

With regard to the first one, the NHC says it continues to produce widespread showers and thunderstorms.

It notes that environmental conditions are expected to be conducive for gradual development of this system, and a tropical depression could form early next week while it moves westward at around 15 mph across the tropical Atlantic.

* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...medium...60 percent.

With regard to the second tropical wave, the NHC says it's producing a large area of disorganized shower and thunderstorm activity.

It says some development of this system is possible over the next few days before upper-level winds become less favorable.  The system is forecast to move westward at 10 to 15 mph across the far eastern tropical Atlantic for the next several days.

* Formation chance through 48 hours...low...30 percent.
* Formation chance through 5 days...medium...40 percent.
