The southwest monsoon arrived over Kerala Sunday, three days ahead of its normal onset date of June 1, the India Meteorological Department (IMD) said.
This is only the fourth occasion since 2010 when the onset of southwest monsoon over Kerala took place before time (June 1). As per IMD records, the monsoon had arrived earlier than usual in 2010 (May 31), 2017 (May 30) and 2018 (May 29). The earliest onset over Kerala since 2005 was recorded in the year 2006, when the monsoon had arrived on May 26.
The declaration regarding the arrival of monsoon was made after the IMD was satisfied with all meteorological parameters including cloud cover over Arabian Sea and Kerala, rainfall over 14 stations in Kerala and the strengthening and depth of westerly winds, among others.
