The northeast monsoon, which brings the major share of Tamil Nadu’s annual rainfall, is likely to commence around October 16, slightly ahead of its normal onset date of October 20.
According to the Regional Meteorological Centre, Chennai, conditions are becoming favourable for the complete withdrawal of southwest monsoon from the country during the first half of the week starting from October 16.
In its bulletin, the RMC has said that this would lead to the simultaneous establishment of easterly/northeasterly winds over southern peninsular region, south and adjoining central Bay of Bengal, paving the way for the onset of the northeast monsoon.
