Correspondingly, Odile was downgraded to a tropical depression early on 12 October, subsequently degenerating into a remnant low about 55 mi (85 km) south of Manzanillo, Colima.

A tropical wave emerged off the west coast of Africa on September 23, and merged with the southern end of a decaying frontal system over the Caribbean Sea.

[3][4] The circulation slowly drifted east-northeastward and became absorbed by a neighboring tropical wave, with the broad resultant low re-curving to the west-northwest.

[7] Despite being in an area with favorable conditions, lack of inner core organization proved difficult for rapid deepening to occur, and initially, model guidance did not forecast any significant strengthening.

[1][8] Based on the improved appearance on satellite imagery, it is estimated the depression intensified into Tropical Storm Odile at 0600 UTC on October 9 about 330 mi (530 km) southeast of Puerto Ángel, Mexico.

[18] As a consequence of the slightly improved organization, Odile had a stronger interaction with the easterlies aloft, therefore increasing forward movement speed.

[18] Later that day, a reconnaissance aircraft passed through Odile and observed a rather weak and disorganized tropical cyclone, resulting in meteorologists at the NHC to change its forecasts.

[1] The last advisory regarding Odile was issued later that day stating that it has subsequently degenerated into a remnant low-pressure area, a swirl of low-level clouds.

[1] On October 11 at around 2 AM PDT, a hurricane watch was declared for the Pacific coast of Mexico from Tecpan de Galeana to Punta San Telmo.

[29] On October 11, a yellow alert were declared for the state of Michoacán, where the civil defense committee also announced that the shelters were opened for schools in the municipality of Lázaro Cárdenas and the towns of Playa Azul and Guacamayas.

[29] The flooding is also responsible for causing strong current that had swept away parked vehicles, downing of at least 16 trees and carrying debris to the main streets of the port.

[34] In Michoacán, strong winds resulted 30 downed trees and the collapse of 5 power poles, leaving 10 minutes without electricity for a large part of the city.
