Meteorological history
Late on October 10, 2017, the Joint Typhoon Warning Center (JTWC) began to monitor an area of low pressure for potential tropical cyclogenesis. At 0:00 UTC the following day, the Japan Meteorological Agency (JMA) designated the system as a tropical depression. However, the JTWC did not follow suit, instead issuing a Tropical Cyclone Formation Alert (TCFA), later that day. Although, the JTWC upgraded the disturbance into a tropical depression, giving it the identifier 24W, at 6:00 UTC on October 12. PAGASA also began to monitor the tropical depression, around this time, naming it Odette. The system began to drift towards the west-northwest, nearing the island of Luzon. Just six hours later, the depression strengthened into a tropical storm, being provided the name Khanun by the JMA. PAGASA upgraded the system into a tropical storm by 14:00 UTC. Roughly three hours later, Khanun made landfall in Santa Ana, Cagayan in the Philippines. As the storm made landfall, the JTWC upgraded it into a tropical storm.
