Although the disturbance does not yet have a well-defined circulation center, ship observations indicate that tropical-storm-force winds are occurring in the northern portion of wave to the southeast of Jamaica, which will spread near or just south of Jamaica later this morning and into this afternoon. Environmental conditions are expected to become a little more conducive for development, and a tropical depression or a tropical storm is likely to form during the next day or so before the system reaches Central America Wednesday night.
