2. A broad area of low pressure located several hundred miles southwest
of the Cabo Verde Islands is producing a large area of disorganized
showers and thunderstorms. Environmental conditions are conducive
for further development, and a tropical depression is likely to form
during the next day or two while the system moves westward to
west-northwestward at 5 to 10 mph over the central tropical
Atlantic.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 5 days...high...90 percent.

2. Showers and thunderstorms remain disorganized in association with a
a broad area of low pressure located several hundred miles southwest
of the Cabo Verde Islands. Environmental conditions are conducive
for gradual development, and a tropical depression could still form
during the next couple of days if the disturbance does not get
absorbed into the stronger low pressure system located to its east.
The broad low is expected to move slowly west-northwestward to
westward over the central tropical Atlantic during the next few
days.
* Formation chance through 48 hours...medium...60 percent.
* Formation chance through 5 days...medium...60 percent.

2. Showers and thunderstorms remain disorganized in association with a
a broad and elongated area of low pressure located several hundred
miles southwest of the Cabo Verde Islands. Although environmental
conditions are generally conducive for development during the next
day or so, interaction of this system with the low pressure area
located to its east is likely to hinder development after that time.
The system is forecast to drift west-northwestward over the next
few days.  
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 5 days...medium...50 percent.

2. Showers and thunderstorms remain disorganized in association with a
a trough of low pressure located several hundred miles southwest of
the Cabo Verde Islands.  Development of this system appears less
likely due to the interaction with the larger low pressure area
located to its east. The system is forecast to drift
west-northwestward over the tropical central Atlantic during the
next few days.  
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 5 days...low...30 percent.

1. Shower activity associated with a trough of low pressure located
over the tropical Atlantic about midway between the Cabo Verde
Islands and the Lesser Antilles has become limited. Environmental
conditions are forecast to become less conducive over the next few
days, and significant development of this system is no longer
anticipated. The disturbance is forecast to move westward at 10
to 15 mph.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...10 percent.
