The southwest monsoon season has set in over Kerala on June 1, according to the India Meteorological Department (IMD). This is the normal date for the onset of the monsoon season over the state and is four days earlier than the date IMD predicted earlier. 

  • The season brings around 70 per cent of the total rainfall that falls over India. 
  • The reason for this is the development of a low-pressure area in the Arabian Sea which is touted to intensify into a cyclone by June 2 and make landfall along the Maharashtra coast, close to Mumbai. 
  • The monsoon winds are south westerly in nature and move towards the north and north west directions. 
  • This might help the cyclone gain in strength and move northwards and further inland after making landfall and decreasing in intensity, according to Raghu Murtugudde, climate scientist at the University of Maryland in the United States.  
  • This might cause rainfall in the interior districts of Maharashtra and Madhya Pradesh.
