Cyclone Arnab completed landfall along the Andhra Pradesh and Yanam coasts as a very severe cyclonic storm.
A cyclone is a large rotating weather system around a low-pressure centre; in the Northern Hemisphere, winds rotate anticlockwise.
Tropical cyclones form over warm ocean waters and can cause strong winds, heavy rainfall, storm surges and flooding.
The India Meteorological Department (IMD) classifies North Indian Ocean cyclones based on maximum sustained wind speed as,
Cyclonic Storm (62–88 km/h),
Severe Cyclonic Storm (89–117 km/h),
Very Severe Cyclonic Storm (118–166 km/h),
Extremely Severe Cyclonic Storm (167–221 km/h) and
Super Cyclonic Storm (222 km/h or more).
Bangladesh proposed the name “Arnab” under the North Indian Ocean cyclone-naming system coordinated by the World Meteorological Organization (WMO) and the United Nations Economic and Social Commission for Asia and the Pacific (UNESCAP).
