Tropical Depression One-E was the earliest tropical cyclone in the calendar year to impact the Mexican state of Sinaloa ever recorded. The first system of the 2009 Pacific hurricane season, One-E formed out of an area of disturbed weather on June 18, 2009, and initially tracked slowly northwards. Throughout the day, convection developed around the center of circulation and the system was anticipated to become a tropical storm. Late on June 18, the National Hurricane Center noted that the system was on the verge of becoming a tropical storm; it would have been named Andres had this occurred. However, the following day, strong wind shear caused the depression to rapidly degenerate into a trough of low pressure before dissipating off the coast of Sinaloa.

Although no longer a tropical cyclone, the remnants of the depression brought moderate rainfall to parts of Sinaloa, Nayarit and Jalisco. High winds accompanied the rainfall and left about 50,000 residences without power. Several trees were downed and some structures sustained damage from fresh water flooding. Landslides occurred along major highways and significant structural damage was reported around Mazatlán. However, there was no loss of life or reports of injuries.
