A sharp meteorological shift is sweeping across India over the next 15 hours, with the India Meteorological Department (IMD) issuing heavy rainfall alerts and thunderstorm advisories covering 23 states, including Uttar Pradesh, Bihar, Madhya Pradesh, and Rajasthan. While the northern plains around Delhi, Haryana, and Chandigarh will see dry skies today before rain returns on October 6, active atmospheric troughs and retreating monsoon winds are driving intense downpours across Northeast India and the southern peninsula. Authorities have urged heightened caution across fragile mountain slopes due to impending landslide risks, especially as isolated regions of Arunachal Pradesh brace for severe torrential rain alongside lightning strikes and fierce surface wind gusts.

Northeast & Himalayan Alert: Severe Downpours in Arunachal Pradesh and Landslide Threats

The weather office highlighted elevated terrain risks across eastern and northeastern belts:

Arunachal Cloudburst & Rain Warning: Isolated localities across Arunachal Pradesh are set to encounter heavy precipitation, creating runoff hazards along river valleys.

Widespread Regional Showers: Scattered to isolated rainfall is projected across Assam, Meghalaya, Nagaland, Manipur, Mizoram, Tripura, Sub-Himalayan West Bengal, Sikkim, and the Andaman and Nicobar Islands.

Thunderstorms, Lightning, and Slope Slips: Intense convective thunderstorm activity paired with dangerous lightning is forecast for Assam-Meghalaya and the Nagaland-Manipur-Mizoram-Tripura belt, prompting landslide warnings in several steep hilly corridors.

Southern Peninsula Storm Watch: 50 Kmph Winds, Extended Wet Spell for Kerala and Tamil Nadu

Active tropical weather setups will trigger sustained downpours across southern coastal and interior pockets:

High-Speed Gusts: Squally winds touching 40 to 50 kmph accompanied by thunderstorms are likely over Tamil Nadu, Puducherry, and Karaikal, while winds reaching 30 to 40 kmph will sweep through Andhra Pradesh, Kerala, Mahe, and Lakshadweep.

Surface Wind Warnings in Andhra: Parts of Andhra Pradesh are on alert for strong surface winds capable of causing minor tree-branch snapping and loose structure disruptions.

Persistent Heavy Rain Spell: Kerala and Mahe will experience substantial showers from October 2 through October 6, Coastal Karnataka will see sustained activity between October 3 and October 6, and intense downpours will batter Kerala, Mahe, Tamil Nadu, Puducherry, and Karaikal from October 4 to October 6.

Clear Skies in Delhi-NCR Today: Rain Rebound From October 6 as Monsoon Retires

While north-central plains enjoy a temporary dry reprieve, changes are brewing for the coming week:

Clear Weather for Capital Belt: No rain is predicted for Haryana, Chandigarh, and Delhi today; however, wet spells are scheduled to restart across the NCR belt from October 6.

Western Himalayan Showers: Uttarakhand will witness fresh showers starting October 5, intensifying significantly by October 7, while Himachal Pradesh will encounter scattered precipitation from October 5 to October 8.

Southwest Monsoon Withdrawal: The southwest monsoon continues its orderly retreat and is expected to pull out further from remaining pockets of Punjab, Haryana, Rajasthan, Uttar Pradesh, Gujarat, Madhya Pradesh, Jammu & Kashmir, Himachal Pradesh, and Uttarakhand over the next 24 hours.
