# IMD forecasts heavy rain in Arunachal, thunderstorms in south India 2026-10-03T00:42:46+00:00 | Governance | Indian Opinion Desk Corroboration: 1 independent outlet The India Meteorological Department (IMD) has forecast isolated heavy rainfall over Arunachal Pradesh on 3 October, with thunderstorms, lightning and gusty winds in parts of south and northeast India. Tamil Nadu, Puducherry and Karaikal may see thunderstorms with gusty winds of 40 to 50 kmph. Similar conditions with winds of 30 to 40 kmph are likely over parts of Andhra Pradesh, Kerala and Mahe, Lakshadweep, and Sub-Himalayan West Bengal and Sikkim. No rain is forecast over Delhi on 3 October, but rainfall activity is expected to increase from 6 October. The IMD added that conditions are becoming favourable for further withdrawal of the southwest monsoon from remaining parts of north and west India over the next 24 hours. ## Indian Opinion Analysis The IMD's forecast for Arunachal Pradesh and south India on 3 October points to a continuing active monsoon phase, even as the southwest monsoon officially withdraws from northern and western states. Residents in Kerala, Tamil Nadu and Karnataka face a wet spell through 6 October, with heavy rain expected from 4 October. For Delhi and Uttar Pradesh, the dry window ends on 5 to 6 October when rain is likely to return. The simultaneous withdrawal and active rainfall highlight the uneven nature of the monsoon's retreat, leaving some regions vulnerable to flooding while others see a delayed dry season. ## Coverage - cnbctv18.com Straight agency-style forecast report, no editorial slant This brief was synthesised by AI from the source linked above.
