The southwest monsoon has arrived over Kerala, marking the start of a four-month long rainfall season, said the India Meteorological Department (IMD) said on Monday.
The four-month monsoon season from June to September accounts for 75 per cent of rainfall in the country.
Private forecaster, Skymet Weather on May 30 had declared arrival of monsoon, but the IMD had differed, saying conditions were not ripe then for such an announcement.
IMD will on Monday release the second stage forecast for the 2020 monsoon season, which will detail the region-wise forecast and also how the rains will perform in the four months
