Synopsis for the Gulf of Mexico

.SYNOPSIS...Disorganized showers and thunderstorms over portions
of Central America and the adjacent waters of the northwestern
Caribbean Sea and southern Gulf of Mexico are associated with a
tropical wave interacting with an upper-level trough. Upper-
level winds over the western Gulf of Mexico are expected to 
become more conducive for development over the weekend, and a 
tropical depression is likely to form on Sunday or Monday while 
the system moves northwestward and then northward near the coast 
of northeastern Mexico. Further development of this system will 
be possible through the middle of next week if it remains over 
water, and interests along the western and northwestern Gulf 
coast should monitor the progress of this system. Regardless of 
development, this disturbance is expected to produce heavy rain 
across portions western Gulf coast, including coastal Texas and 
Louisiana through the middle of next week. Expect an increase in 
winds and seas along these regions with this system. Meanwhile, a
frontal boundary over the northern Gulf will prevail through Sun
supporting showers and thunderstorms across the region.
