It was also the earliest-forming storm in both the Northwestern Pacific Ocean and North Indian Ocean basins on record. Forming on the last day of 2018, Pabuk persisted into 2019, spanning two calendar years, and crossed into the North Indian Ocean basin several days later. The first tropical cyclone and named storm of the 2019 Pacific typhoon and North Indian Ocean cyclone seasons, Pabuk originated as a tropical disturbance in the South China Sea on December 28, 2018, which organized into a tropical depression on December 31. A day later, on January 1, 2019, the system intensified into a tropical storm and was named Pabuk. Pabuk made landfall in Thailand on January 4, emerging into the Bay of Bengal in the North Indian Ocean basin shortly afterward. Pabuk weakened after it entered the North Indian Ocean, eventually degenerating into a remnant low on January 7, before dissipating on the next day.
