Meteorological history
On November 24 an area of low pressure formed over land in Sri Lanka. Later that day the Joint Typhoon Warning Center assessed the low-pressure area's chance of becoming a significant tropical cyclone within 24 hours as 'poor', due to the minimal convection near the low-level circulation center. The next morning the JTWC issued a Tropical Cyclone Formation Alert on the low-pressure area, stating it had a 'good' chance of becoming a significant tropical cyclone within 24 hours, as the Low Level Circulation Center was moving into the Bay of Bengal. Two hours later the IMD upgraded the area of low pressure to Depression BOB 07. Three hours later the India Meteorological Department reported that the depression had intensified into a Deep Depression whilst remaining stationary.
