Weather Alerts and Expected Conditions
The India Meteorological Department (IMD) placed Delhi under a yellow alert on October 29, 2026, warning of light to moderate rain, thunderstorms, lightning and gusty winds of 40–50 kmph in the morning, easing later. Temperatures were forecast to hover around a maximum of 27 °C and a minimum of 17 °C.
On October 30, 2026, the IMD upgraded parts of the capital and neighbouring states to red and orange alerts, indicating a higher likelihood of moderate to heavy rainfall, hailstorms and wind gusts up to 70 kmph in isolated locations. Thunderstorms accompanied by hail were described as “very likely” over central and western districts.

Official Statements & Responses
The IMD advised residents to exercise caution during lightning, hail and strong winds, avoid sheltering under trees, and secure loose objects. Commuters were urged to allow extra travel time and stay informed through official bulletins.
An IMD official noted that a western disturbance over north-Pakistan and a cyclonic circulation over Haryana were interacting to produce the unsettled weather across the northern plains.
04
Impact on Karwa Chauth Observances
The same system threatened visibility of the moon on Karwa Chauth, a Hindu fasting ritual that requires sighting the moon before breaking the fast. Overcast skies and possible hail raised concerns that the moon may not be visible, potentially delaying the ritual for fasting women across Delhi-NCR and the Tricity (Chandigarh, Mohali, Panchkula).
05
On-the-Ground Reports
Social-media posts from residents in Preet Vihar, Dwarka, Laxmi Nagar, Nirman Vihar and Yamuna Bank documented sudden showers and hail on the afternoon of Oct 29. Photographs showed wet streets, water-logged potholes and hailstones on rooftops.
06
Why It Matters
- Public health: An AQI of 229 places the capital in the “poor” category, increasing breathing discomfort for vulnerable groups.
- Transportation safety: Strong gusts and lightning raise the likelihood of road accidents, especially for two-wheelers and pedestrians.
- Cultural significance: Disruption of Karwa Chauth moon-sighting affects a widely observed religious practice.
07
Conflicting Reports & Gaps
Temperature forecasts vary: some outlets project a maximum of 27 °C on Oct 29, while others cite 32 °C. The IMD’s official bulletin lists 27 °C, but the discrepancy remains unclarified. Precise contributions of Cyclone Arnab to Delhi’s rainfall are noted as “to be confirmed” in later reports.
08
What’s Next
The IMD’s seven-day outlook indicates partly cloudy conditions on October 31, 2026, suggesting a tapering of rain after the late-week spell. A separate forecast notes that clear weather is expected to return across the region by November 1, 2026. Residents are encouraged to monitor updated IMD bulletins for any further changes.
