Extended interaction with land proved detrimental to the storm, and it began to rapidly disintegrate. Just 18 hours after its final bout of strengthening, Nepartak had been reduced to an exposed circulation center with no associated thunderstorms.[1] Turning toward the northeast, the system had been concurrently downgraded to a tropical depression by the JTWC and JMA early on November 19.[3][5] The weak remnant low of Nepartak limped ashore over Beihai, China at 1900 UTC and dissipated shortly thereafter.[1]
