- The Indian National Centre for Ocean Information Services had issued a warning to States of Kerala, South Tamil Nadu, Puducherry and Lakshadweep.
- Swell waves are long-wavelength ocean waves that travel away from their places of origin.
- They are usually created by windstorms or other weather systems.
- Sea waves otherwise are usually generated due to local winds.
- Windstorms and other powerful air current systems transfer energy from the air to water, making swell waves more powerful than locally generated waves.
- Because of their high energy, swell waves are able to travel large distances and strike shores with considerably high power.
- Swell waves are also called Kallakkadal waves in India, which is a colloquial term used by Kerala fishermen.
- The term has now been approved for scientific use by UNESCO.
