Guwahati: India Meteorological Department (IMD) said on Thursday that conditions are favourable for monsoon to reach the northeast in the next two to three days, as it announced the onset of the southwest monsoon in Kerala.After heavy to very heavy rainfall was recorded at isolated places in several northeastern states over the past 24 hours, the Met office predicted that heavy to very heavy rain will continue across the northeast for the next five to six days.“Conditions are favourable for further advance of southwest monsoon into some more parts of central Arabian Sea, entire Goa, some parts of Maharashtra and Andhra Pradesh, some more parts of Karnataka, remaining parts of Tamil Nadu, Southwest Bay of Bengal, some more parts of Westcentral, East central and Northeast Bay of Bengal, some parts of northeastern state during next 2-3 days,” the IMD said on Thursday.The normal monsoon onset date in the northeast is June 5, and this year the onset across the region is expected to be almost simultaneous, Met officials added.Met officials said a heavy spell is likely with the onset of monsoon, which could help farmers who have been waiting to begin ploughing paddy fields in states such as Assam, the northeast’s largest paddy-producing state.According to the latest Long Range Forecast for the Southwest Monsoon Seasonal Rainfall during June–September, rainfall during the monsoon months (from June to September) is most likely to be normal over Northeast India—94 to 106% of the Long Period Average (LPA)—and below normal over Central & South Peninsular India (
