On Oct 30, 2026, the Indian Meteorological Department (IMD) issued a severe weather alert calling for heavy rainfall and thunderstorms across Delhi and much of eastern, central, and southern India, driven by a depression formed from Cyclone Arnab and a western disturbance.
The alert notes that Delhi will see continuous rain in the west and north for the next five to six hours, followed by light to moderate showers as early as 6:30 p.m., with maximum temperatures capped at 29 °C and minimums at 18 °C.
Thunderstorms with hail are expected in Haryana, Chandigarh, Delhi, and Punjab, while thundersqualls could deliver winds up to 40 km/h, potentially damaging power lines and uprooting trees.
Elsewhere, Odisha, coastal Andhra Pradesh, and Yanam have already recorded extreme rainfall; the forecast predicts 70 mm or more in east Chhattisgarh and north Odisha on Oct 30, with Jharkhand facing lightning‑laden storms.
The IMD also warned of a low‑pressure system over the southern Andaman Sea that will move west‑northwest, intensifying over the Bay of Bengal around Oct 31 before heading toward the Andhra Pradesh coast.
Local authorities in Delhi have mobilised 15 emergency response teams and set up temporary shelters for over 3,000 residents displaced by yesterday’s floods; a resident of Faridabad said he will keep his family indoors until the weather clears.
