IMD orange alert for Delhi-NCR: Heavy rain, thunderstorms on Oct 15-16
Synopsis
Key Takeaways
The India Meteorological Department (IMD) issued an orange alert for Delhi-NCR on Thursday, 15 October as heavy rain and thunderstorms swept through the national capital, with the weather agency warning of continued showers, lightning, and gusty winds into Friday, 16 October. Dark clouds blanketed the city through the day, marking a sharp break from the warm conditions that had prevailed earlier this week.
What the IMD Forecast Says
The department warned of moderate to intense rainfall in parts of north and northwest Delhi, with wind speeds forecast at 40–50 kmph and gusts of up to 60 kmph. Lighter showers and thunderstorms are expected across the remaining parts of the capital. The maximum temperature is forecast to hover around 29 degrees Celsius — noticeably lower than readings recorded earlier this week.
According to the IMD, conditions are likely to ease from Saturday, 17 October, when partly cloudy skies and a maximum of around 32 degrees Celsius are expected. By Sunday, 18 October, skies are forecast to turn mainly clear, with daytime temperatures rising further.
The Weather Driver: Western Disturbance
The current wet spell is associated with a western disturbance — a weather system that moves eastwards from regions west of India and periodically triggers rain and thunderstorms across the country's northern belt. This type of system is a recurring feature of October weather in the region, though the intensity of rainfall can vary considerably across localities.
Areas Likely to Be Affected
Beyond Delhi, neighbouring satellite cities — Noida, Gurugram, Ghaziabad, and Faridabad — are also expected to receive showers, though the IMD has noted that rainfall distribution and intensity may differ across the region. The orange alert, which sits one level below the most severe red alert, signals that residents and authorities should remain prepared.
Impact on Traffic, Air Quality and Daily Life
Rain, lightning, and gusty winds could disrupt traffic and outdoor activities, particularly in areas receiving heavier downpours. Waterlogging on roads is a concern during peak commute hours. On the air quality front, the rainfall may temporarily wash out particulate matter, but any sustained improvement in Delhi's air quality index will depend on the intensity of showers and wind patterns in the hours that follow — a dynamic the IMD is continuing to monitor.
Residents are advised to stay indoors during peak storm activity and avoid waterlogged streets. The weather picture is expected to become clearer — literally and figuratively — by the weekend.
