Cyclone Arnab nears the coast; Andhra Pradesh and Odisha step up evacuations
Cyclone Arnab has intensified over the Bay of Bengal, and Andhra Pradesh and Odisha have stepped up evacuations. The Cabinet Secretary chaired a National Crisis Management Committee (NCMC) meeting on 26 October to review preparedness. The IMD expects landfall on the Andhra Pradesh–Yanam coast between Bapatla and Visakhapatnam around 28 October.
Why in news
Forecast: Maximum sustained winds of 115–125 km/h, gusting to 140 km/h. Heavy to extremely heavy rain over coastal Andhra Pradesh and south Odisha. Rain effects may extend to Telangana, Chhattisgarh, Bihar and eastern Uttar Pradesh. Preparedness: Evacuation to cyclone shelters in vulnerable areas. NDRF and SDRF teams deployed and district control rooms activated. Fishermen advised to stay off the sea. Army, Navy, Air Force and Coast Guard teams on standby. About the name: "Arnab" was contributed by Bangladesh and means "ocean" in Bengali. In September 2026, a Bay of Bengal system was widely called "Cyclone Arnab", but the IMD classified it only as a deep depression, so it was never formally named. The name was used only now, once a system reached cyclonic-storm strength.
Prelims pointers
- Cyclones in the North Indian Ocean are named by RSMC New Delhi (IMD) from a list prepared by the WMO/ESCAP Panel on Tropical Cyclones (13 member countries, 169 names adopted in 2020).
- A system gets a name only on reaching cyclonic-storm intensity (62–88 km/h).
- IMD scale: Depression 31–49, Deep Depression 50–61, Cyclonic Storm 62–88, Severe 89–117, Very Severe 118–166, Extremely Severe 167–221, Super Cyclonic Storm 222 km/h and above.
- Cyclone formation needs warm sea water (about 26.5°C or more), Coriolis force, high humidity and low vertical wind shear. Cyclones rarely form at the Equator.
- Yanam is an enclave of the Union Territory of Puducherry on the Andhra Pradesh coast.
- The Bay of Bengal sees most of India's cyclones, with peaks in the pre-monsoon (April–May) and post-monsoon (October–December) seasons.
Mains angle
India has cut cyclone deaths sharply through better forecasting and mass evacuation (the Odisha model). Losses to housing, crops, power and fisheries still remain high. Priorities: Last-mile warnings for fishing villages. Cyclone-resistant housing and power lines. Mangrove and coastal ecosystem protection. Faster restoration and livelihood support after landfall.
