The monsoon is likely to hit Kerala on May 30, a day or two earlier than the previous forecast by the Indian Meteorological Department (IMD), suggests their latest report. The onset of southwest monsoon over Kerala signals the arrival of monsoon over the Indian subcontinent. The southwest monsoon advances over the Andaman sea usually around May 20 with a standard deviation of about a week, but recent formations of cyclonic circulation over the sea have sped the monsoon. It also resulted in an early onset of monsoon in parts of southeast Bay of Bengal, Andaman and Nicobar islands. The forecasts of the monsoon onset issued during the past 12 years (2005-2016) were proved to be correct for all years except 2015.
