Deep convection persisted to the west of the system while the circulation continued to develop over the next 24 hours, and the IMD started tracking it as a depression, with the identifier ARB 02. ARB 02 continued to develop and by the night of 22 June, the JTWC issued a TCFA on the system, while it was 285 nmi west-northwest of Mumbai.
