Delhi-NCR Witnesses Rain and Strong Winds, IMD Issues 14-State Alert

The weather pattern in Delhi and the National Capital Region (NCR) underwent a significant transformation on Monday afternoon. Dense clouds enveloped the sky, followed by light to moderate rainfall in several areas. The sudden showers, accompanied by gusty winds and thunder, provided much-needed relief to residents from the rising mercury levels. According to the India Meteorological Department (IMD), this change is attributed to the influence of two active Western Disturbances over North India. The weather office has issued a 'Yellow Alert' for the region, predicting continued thundershowers and dust storms throughout the day.

Atmospheric Changes and Wind Velocity in Delhi-NCR

Meteorological officials have noted that the atmospheric pressure changes have led to sustained cloud cover over the capital, while surface winds are expected to maintain a speed of 30 to 40 kmph, with occasional gusts reaching up to 50 kmph. These high-velocity winds have caused a slight dip in visibility in some parts of the city. The IMD reports that the rain and wind are likely to wash away pollutants, potentially improving the Air Quality Index (AQI) across the metropolitan area. Weather stations at Safdarjung, Palam, and Lodhi Road have already recorded a noticeable drop in ambient temperatures following the initial spells of rain.

Regional Weather Alerts Across 14 Indian States

The impact of the current weather system extends far beyond the national capital. The IMD has placed 14 states under various levels of weather alerts. States including Uttar Pradesh, Punjab, Haryana, Rajasthan, and Chandigarh are expected to witness rainfall and thunderstorms over the next 48 hours. In Rajasthan, the disturbance is likely to trigger dust storms in the western districts. Also, heavy rainfall warnings have been issued for Central and Eastern India, covering Madhya Pradesh, Chhattisgarh, Bihar, Jharkhand, West Bengal, and Odisha. In South India, Kerala is on high alert for heavy precipitation between March 31 and April 1, as per official forecasts.

Snowfall in Hilly Regions and Hailstorm Risks

The Western Disturbance is exerting a strong influence on the Himalayan belt. Higher reaches of Jammu and Kashmir, Himachal Pradesh, and Uttarakhand are experiencing fresh snowfall, while the lower valleys receive heavy rain. Authorities in Kashmir have warned of potential disruptions to vehicular traffic on major highways due to the snow. In the plains, particularly in parts of Punjab and Haryana, there is a significant risk of hailstorms. Agricultural experts have expressed concern that hailstones could damage standing crops such as wheat and mustard, which are nearing the harvest stage. Farmers have been advised to monitor weather updates closely to protect their produce.

Temperature Trends and Relief from Early Summer Heat

Prior to this weather shift, Delhi had been recording maximum temperatures near 35 degrees Celsius. However, the current spell of rain has brought the mercury down. The IMD predicts a maximum temperature of 33 degrees Celsius and a minimum of 20 degrees Celsius for today. A further decline of 2 degrees Celsius in the minimum temperature is expected by Tuesday, leading to cooler nights. This cooling trend is consistent across Northwest India, where maximum temperatures are projected to remain 3 to 5 degrees Celsius below normal for the next few days. The absence of heatwave conditions provides a temporary reprieve as the region transitions into the peak summer months.

Extended Forecast and Atmospheric Outlook

According to the latest IMD bulletins, the influence of the Western Disturbances is likely to persist until the middle of the week. A gradual clearing of the skies and an increase in sunshine are expected from April 2 onwards. During this period, humidity levels are anticipated to remain high, while in Northeast India, states like Assam and Meghalaya are also slated to receive scattered rainfall and thunderstorms. While the first week of April may see a return to warmer conditions, the current atmospheric instability has effectively delayed the onset of extreme heat. Coastal regions, however, may continue to experience humid conditions despite the regional cooling in the north.
