Cyclone Arnab approached the Andhra coast, and IMD issued orange alerts across several states, including Karnataka, with heavy rain and a drop in temperatures.
A lingering low-pressure system near Tamil Nadu may have added moisture but did not merge with it.
Commentators credit proactive governance for the low casualties.
Cyclones of the North Indian Ocean are named from a list proposed by member countries of the WMO/ESCAP Panel on Tropical Cyclones, with IMD New Delhi as the regional specialised centre.

How the exam will ask it
ପ୍ରିଲିମ୍ସ
- IMD, New Delhi is a WMO Regional Specialised Meteorological Centre for tropical cyclones over the North Indian Ocean.
- Names of North Indian Ocean cyclones are drawn from a list proposed by member countries of the WMO/ESCAP Panel on Tropical Cyclones.
- IMD's colour-coded warnings run from green to red; orange asks authorities and public to be prepared for severe weather.
ମେନ୍ସ
GS1 (Geography: cyclones) and GS3 (Disaster management). Issue: a cyclone brings heavy rain and orange alerts across several states. Provision/policy: early warning by IMD as RSMC, backed by the Disaster Management Act, 2005 and NDMA/SDMA preparedness. Implication: low casualties show the value of early warning and coordination; way forward is stronger last-mile alerts, resilient coastal infrastructure and clear attribution of causes rather than credit claims.
