About Cyclone Remal:

Named ‘Remal’ by Oman, it’s the first cyclone of the 2024 pre-monsoon season in the Bay of Bengal.
‘Remal’ means ‘sand’ in Arabic, originating from the Bay of Bengal.
Formation factors: A depression in the central Bay of Bengal serves as the genesis for Cyclone Remal.
Potential impact: Shallow bathymetry and funnel-shaped geography in the northern Bay of Bengal can amplify cyclone intensity, leading to storm surges and flooding risks.
