Tropical Atlantic:
Showers and thunderstorms associated with a tropical wave located
over the eastern tropical Atlantic several hundred miles
west-southwest of the Cabo Verde Islands remain disorganized.
Environmental conditions are conducive for development of this
system during the next several days, and a tropical depression is
likely to form late this week or this weekend over the eastern or
central tropical Atlantic while moving slowly toward the
west-northwest at 5 to 10 mph. The system is likely to move faster
toward the west or west-northwest thereafter and reach the waters
east of the Lesser Antilles by the middle of next week.
