NEW DELHI, Oct. 1 -- The 2019 southwest monsoon officially came to an end on Monday, with the India Meteorological Department announcing that the country had received the heaviest rainfall in 25 years, and classifying the weather pattern as 'above normal'.

The withdrawal of the monsoon, however, is likely to begin only around October 10 - the longest delay since data first started being recorded. The previous record for the biggest delay of the summer monsoon was in 1961: October 1. The monsoon usually starts withdrawing in the first week of September from northern India.

"Quantitatively monsoon seasonal rainfall was 110 per cent of its Long Period Average (LPA)," the IMD said. On Monday, Bihar received 1,468% above normal rainfall.
