Severe Cyclonic Storm Mandous[a] (/mændəs/) was the third cyclonic storm, as well as the third most intense tropical cyclone of the 2022 North Indian Ocean cyclone season. The remnants of the system later regenerated into Deep Depression ARB 03 in the Arabian Sea. The system struck the Andaman and Nicobar Islands, as well as South India.
The Indian Meteorological Department issued a bulletin stating that a tropical depression had formed in the Bay of Bengal and was designated BOB 09.[5] 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.[6] A day later, both the JTWC and IMD classified this low pressure as a "cyclonic storm" and it was named Mandous.[7][8] Mandous continued tracking westward, and later, attaining wind speeds of 65 mph (105 km/h; 56 kn), strengthened into a Severe Cyclonic Storm.[9][10] 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.[11]
Regeneration
On December 14, the remnants of Cyclone Mandous regenerated into a depression in the Arabian Sea, and it was called ARB 03.[12] 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,[13] 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.
Preparations
In Puducherry and Karikal, colleges and schools were closed in anticipation of the storm.[14]
Impact
In Chennai, about 200 trees were uprooted due to Cyclone Mandous.[15] Damage in Anantapur was Rs45 million (US$550 thousand).[16] Four people died Tamil Nadu from heavy rains. Five fishermen went missing off the coast of Sri Lanka due to the storm.[17][18]
