The southern portion of the tropical wave which spawned Hurricane Gordon in the Gulf of Mexico moved
westward through central America into the tropical eastern Pacific on September 16th. The wave moved
through a pre-existing gyre of low pressure south of Mexico, which produced a large area of disturbed
weather. The system slowly became better organized forming into a tropical depression on the morning of
the 20th and a tropical storm just prior to landfall between Lazaro Cardenas and Colima. Weakening
thereafter, it quickly regained tropical depression status and moved slightly offshore before striking
Mexico a second time near Mazatlan. The remnant tropical disturbance moved up the Sierra Madre
Occidental towards Arizona. Below is its track, supplied by the National Hurricane Center.
The graphics below show the storm total rainfall for Norman, which used information from the Comision
Nacional del Agua, parent agency of Mexico's National Weather Service.
