Over the past fifty years, Andhra Pradesh has endured the devastating impact of 60 cyclones, with 40 of these classified as ‘very severe,’ according to data from the Andhra Pradesh Disaster Management Authority. This cyclone-prone region, particularly vulnerable between September and December, has witnessed extensive destruction and loss of life due to these natural disasters.
September has been notably harsh, with significant cyclonic activity, such as Cyclone DAYE in 2018 and the deadliest September storm in 2005 that claimed 105 lives. October has been no less severe, with Cyclone Titli in 2018 affecting eight districts and Cyclone Hudhud in 2014 impacting 92.78 lakh people across four districts.
November cyclones, such as Nivar in 2020 and Helen in 2013, have also wreaked havoc, each impacting multiple districts and leaving a trail of destruction. Even December, traditionally less cyclone-prone, has seen notable storms like Mandodus in 2022 and Vardah in 2016. The infamous Diviseema Cyclone of 1977 remains etched in the collective memory of Andhra Pradesh for the devastation it caused along the coastline from Srikakulam to Guntur.
Stella S, director of the IMD Amaravati bureau, shed light on why Andhra Pradesh faces a high frequency of cyclones during these months. “The movement of the Intertropical Convergence Zone (ITCZ), combined with favorable sea surface temperatures and vorticity, creates ideal conditions for cyclone formation after the monsoon season,” she explained. Meteorology professor P. Sunitha added, “The Bay of Bengal’s warming during October leads to evaporation and moisture buildup, which can trigger cyclone development within 45 days of the monsoon’s retreat.”
Despite the ongoing challenges, there is a temporary respite as no cyclonic activity is expected in the coming two weeks. However, the state remains vigilant, continuously improving disaster preparedness to mitigate the impact of future cyclones.
