Intro to cylones:
In meteorology, a cyclone is an area of closed, circular fluid motion rotating in the same direction as the Earth.[1][2] This is usually characterized by inward spiraling winds that rotate anti-clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere of the Earth. Most large-scale cyclonic circulations are centered on areas of low atmospheric pressure.[3][4] The largest low-pressure systems are cold-core polar cyclones and extratropical cyclones which lie on the synoptic scale. According to the NHC glossary, warm-core cyclones such as tropical cyclones and subtropical cyclones also lie within the synoptic scale.[5] Mesocyclones, tornadoes and dust devils lie within the smaller mesoscale.[6] Upper level cyclones can exist without the presence of a surface low, and can pinch off from the base of the Tropical Upper Tropospheric Trough during the summer months in the Northern Hemisphere. Cyclones have also been seen on extraterrestrial planets, such as Mars and Neptune.[7][8] Cyclogenesis describes the process of cyclone formation and intensification.[9] Extratropical cyclones form as waves in large regions of enhanced mid-latitude temperature contrasts called baroclinic zones. These zones contract to form weather fronts as the cyclonic circulation closes and intensifies. Later in their life cycle, cyclones occlude as cold core systems. A cyclone's track is guided over the course of its 2 to 6 day life cycle by the steering flow of the cancer or subtropical jet stream.

The cyclone would also lead to partial disruption of power and communication lines. D.M:intro:

National Institute of Disaster Management (Hindi: राष्ट्रीय आपदा प्रबंधन संस्थान ) abbr. NIDM, is a premier institute for training and capacity development programs for managing natural disasters in India, on a national as well as regional basis. The National Centre of Disaster Management (NIDM), constituted under an Act of Parliament in 1995; was redesignated to give the present name of National Institute of Disaster Management (NIDM) by the Disaster Management Act 2005[1] passed by President of India on 9 January 2006,[2] NIDM also serves as international SAARC Disaster Management Centre (SDMC) and works as focus for its operation and planning.
