The normal date of onset is June 1, but Skymet reiterated that the onset date has no bearing on its further advancement to other parts of the country. 

The IMD has said that the low over the South-East Bay and adjoining South Andaman Sea has become well-marked, a step away from being called a depression. It may reach depression strength on Friday over the central parts of the South Bay and further intensify into a cyclone by Saturday evening.

The onset of Southwest Monsoon over Kerala has a standard deviation of 7 days which indicates that on maximum occasions the event occurs between May 25 to June 8. In the last 10years, the earliest arrival was on May 23 in 2009 and the most delayed on June 8, 2016.
