south-southwest of the Gulf of Tehuantepec is producing a large
area of disorganized showers and thunderstorms.  Environmental
conditions are expected to be conducive for gradual development,
and a tropical depression is likely to form during the middle to
later part of this week as it moves west-northwestward or
northwestward at 10 to 15 mph.
