1. A trough of low pressure is producing a large area of disorganized
cloudiness and thunderstorms over the northwestern Caribbean Sea,
the Yucatan Peninsula, and northern portions of Central America.
This system is expected to reach the southern Gulf of Mexico later
this weekend, and will begin to interact with an upper-level low
located near the Texas coast.  This interaction should result in the
development of a broad and complex area of low pressure that moves
northward over the Gulf of Mexico early next week.  Although
environmental conditions are not expected to be conducive for
tropical cyclone formation, this disturbance is likely to produce
locally heavy rainfall over portions of the northern Gulf coast and
southeastern United States early next week.
