A tropical wave moved across Central America into the far eastern north Pacific ocean by August 28th.  The
 system moved westward with no signs of development until September 1st, when an upper level low to its north
across the Gulf of Mexico caused an area of thunderstorms to form just south of the Mexican coastline.  An upper
trough developed across the southern Plains of the United States, which slowly lured the northern portion of this
increasingly large disturbance northward through the Mexican Isthmus.  The southern portion moved westward,
developing into Hurricane Marie.  For a short while, Marie acted as a source of vertical wind shear from the west
for this system, halting further development. 

By the 6th, the disturbance had emerged into the southwest Gulf of Mexico and consolidated into a smaller system
which had enough organization to be classified as a tropical depression, the seventh of the season.  The depression
moved north-northwest into northeast Mexico on the afternoon of the 7th, dissipating completely on the 8th.  Below
is a storm total rainfall map for the tropical depression, using data from the Servicio Nacional del Agua, the parent
agency of Mexico's National Weather Service.
