A broad area of low pressure, associated with a tropical wave, is
producing a large area of disorganized showers and thunderstorms
just off the west coast of Africa.  Environmental conditions appear
conducive for gradual development of this system, and a tropical
depression could form by the middle to latter portion of next week
while moving west-northwestward 20 mph or 32 km/h across the eastern
and central tropical Atlantic.
