However, environmental conditions are conducive for development, and
a tropical depression is expected to form within the next day or two
while the system moves slowly westward or west-northwestward across
the tropical Atlantic Ocean.
* Formation chance through 48 hours...high...80 percent.
* Formation chance through 5 days...high...90 percent.

Updated: A tropical wave with an accompanying low pressure area is
forecast to move off the west coast of Africa on Friday.  This
system is already showing signs of organization, and a tropical
depression is likely to form over the weekend or early next week
while the wave moves westward or west-northwestward over the far
eastern tropical Atlantic Ocean.  Interests in the Cabo Verde
Islands should monitor the progress of this system.
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 5 days...high...80 percent.
