The next day, it crossed into the Andaman Sea and lingered there, organizing further throughout the day and intensified into a depression over the Bay of Bengal on November 10. The next day, the system was designated by the IMD as BOB 09. Soon after, the Joint Typhoon Warning Center (JTWC) issued a Tropical Cyclone Formation Alert (TCFA).

At 00:00 UTC on November 11, the deep depression strengthened into a cyclonic storm, and was given the name Gaja by the IMD.
