Meteorological history.
The Indian Meteorological Department issued a bulletin stating that a tropical depression had formed in the Bay of Bengal and was designated "BOB 09". The JTWC, released a TCFA on the system, stating that it could intensify further, because of very warm waters and low to moderate wind shear, designating it "Invest 96B". A day later, both the JTWC and IMD classified this low pressure as a "cyclonic storm" and it was named "Mandous". Mandous continued tracking westward, and later, attaining wind speeds of , strengthened into a Severe Cyclonic Storm. As it continued tracking westward, land interaction caused in to fall to Cyclonic Storm intensity. It later made landfall around Chennai, India as a Deep Depression. It fell to Depression intensity, and later degenerated into a remnant low.
Regeneration.
On December 14, the remnants of Cyclone Mandous regenerated into a depression in the Arabian Sea, and it was called ARB 03. The Joint Typhoon Warning Center dubbed it as "Invest 97A". Although forecasted to quickly degenerate into a remnant low, ARB 03 intensified into a Deep Depression, according to the Indian Meteorological Department, and the JTWC dubbed it as "Cyclone 07A". After reaching peak intensity, the Low-Level Circulation detached from the associated convection, and wind shear increased, starting a weakening trend. It weakened into a low pressure area at 12:00 UTC on December 17.
