  • Recently, the India Meteorological Department (IMD) reported that Cyclone Asna has formed over the Kutch coast in Gujarat and adjoining areas of Pakistan.
  • Since 1891, only three cyclonic storms have occurred in the Arabian Sea in August, with the most recent one before 2023 being in 1976.
  • A well-marked low-pressure area – a very early precursor to a cyclone – has formed in the Bay of Bengal off north Andhra Pradesh and south Odisha.
  • Cyclone Asna caused torrential rain in Gujarat, leading to 26 deaths, the relocation of 18,000 people, and the rescue of 1,200 from floods.
  • Formation: Cyclones form over warm ocean waters where moist air rises, creating a low-pressure system. This system intensifies due to the Coriolis effect, forming a rotating storm with strong winds.
  • Cyclone Asna, named by Pakistan, means “the one to be acknowledged or praised.”
    • Naming of Cyclones: Names are chosen from a list of suggestions submitted by member countries. The names are often easy to pronounce, culturally relevant, and avoid being offensive.
