Synopsis for the Gulf of Mexico

.SYNOPSIS...The northern portion of a tropical wave is producing
disorganized showers and thunderstorms across the western
Caribbean Sea. This system is forecast to move into the Bay of
Campeche and merge with a pre-existing surface trough located
over the southwestern Gulf of Mexico by this weekend. Environmental
conditions are expected to be conducive to support some gradual 
development, and a tropical depression could form by early next 
week before the system moves inland over mainland Mexico. This 
system has a low chance of development in 48 hours and medium 
chance in the next 5 days. Regardless of development, this system
could bring an increase in winds and seas across the Gulf waters
during the upcoming weekend.
