The average, or normal, rainfall in the country is defined between 96 and 104 per cent of a 50-year average for the entire four-month monsoon season. If it is normal, the country will record 887 mm for the four-month period from June to September. “The onset month of June and the withdrawal month of September give a promising picture in terms of good countrywide rainfall distribution,” Skymet said in its report. The official forecaster, India Meteorological Department, is expected to come up with its monsoon predictions later this month. In its forecast bulletin, Skymet drew up three more scerios likely for the season — ranging from below normal to excess rainfall with an error margin of plus-minus 5 per cent.
