An initial band of moisture associated with Tropical Depression Odile, once rated as strong as a Category 4 hurricane, contributed to heavy rainfall in Greenlee County on September 16th. A precipitable water value of 1.91 inches was noted on the Tucson sounding at 1200 UTC September 17th. Odile took a sharp turn to the east later that day, which limited rainfall from Tucson westward, although widespread heavy rain fell in Cochise, Santa Cruz and southeast Graham Counties. From the afternoon of September 17th into the early morning hours of September 18th, rainfall amounts of 1 to 3 inches were common with locally heavier amounts of 4 to 6 inches reported. Multiple reports of flooding were received due to both flash flooding and river flooding.

Multiple road and bridge closures occurred in response to heavy rainfall across much of Cochise County. Increased flows on the San Pedro River eventually over-topped both the Highway 92 bridge in Palominas and the Hereford Bridge, causing both to be closed for a period of time. The Hereford Bridge sustained damage, and it did not re-open until nearly a month later on October 16, 2014. Further east, rainfall in the Old Bisbee area weakened a portion of a hillside. Falling soil and rock collapsed a retaining wall which fell onto a vehicle, while another residence sustained damage. The bridge at Cave Creek Road near Portal which leads to Cathedral Rock cabins was completely washed out. Water rushed around several buildings up to 2 feet deep in some locations but little damage occurred. One resident was evacuated from her home as a precaution. Additionally, many roads in rural Cochise County were closed for a time due to areal flooding.
