Very Severe Cyclonic Storm Nivar[a] (/nɪ'vɑː(ɹ)/) was a tropical cyclone which brought severe impacts to portions of Tamil Nadu and Andhra Pradesh in late November 2020. The eighth depression and fourth named storm of the 2020 North Indian Ocean cyclone season, Nivar originated from a disturbance in the Intertropical Convergence Zone. The disturbance gradually organized and on 23 November, both the Joint Typhoon Warning Center (JTWC) and the India Meteorological Department (IMD) reported that a tropical depression had formed. On the next day, both agencies upgraded the system to a tropical storm, with the latter assigning it the name Nivar. Nivar made its landfall over north coastal Tamil Nadu between Puducherry and Chennai close to Marakkanam. Overall, Nivar caused $600 million in damages.[2]
