An area of convection first appeared on May 4.
It slowly moved eastwards and organized into a low pressure area on May 8.
A pulse in the Madden–Julian oscillation, together with a convective Kelvin wave allowed the system to develop.
These oscillations also caused Tropical Storm Jamala to form.
The JTWC later issued a Tropical Cyclone Formation Alert (TCFA) on May 10, after the system became more organized.
The IMD upgraded it to a well-marked low pressure area.
Later the same day, JTWC issued the first warning for the storm.
JTWC designed it 01B, followed by the IMD upgrading the storm into a depression, and later into a deep depression.
