The arrival of the Northeast Monsoon is crucial for Tamil Nadu, as it replenishes water resources and mitigates rainfall deficits. However, during the transition phase, some areas, particularly north interior Tamil Nadu, may experience above-normal temperatures until October 14. Additionally, a weather system over the Gulf of Mannar and south Tamil Nadu could trigger light to moderate rainfall in southern and interior regions until October 16. Elevated temperatures may persist in areas lacking sustained cloud cover.
