1. Central Tropical Atlantic (AL92):   An elongated area of low pressure located over the central tropical Atlantic continues to produce some disorganized shower and thunderstorm activity. Environmental conditions appear only

marginally conducive for some slight development during the next couple of days, but a tropical depression could still form during that time while the system moves westward at 5 to 10 mph over the central tropical Atlantic.

* Formation chance through 48 hours...low...30 percent.

* Formation chance through 7 days...low...30 percent.

 

2. Eastern and Central Tropical Atlantic:  A trough of low pressure over the eastern tropical Atlantic is producing a large but disorganized area of showers and thunderstorms from near the Cabo Verde Islands extending  southwestward for several hundred miles.  Environmental conditions appear favorable for gradual development of this system, and a tropical depression will likely form during the latter part of this week while the system moves west-northwestward at 10 to 15 mph.

* Formation chance through 48 hours...medium...40 percent.

* Formation chance through 7 days...high...80 percent.
