Western Disturbance to Bring Rainfall and Intense Cold in Delhi: IMD Forecasts the Season’s Harshest Chill

New Delhi, January 19 – The Indian Meteorological Department (IMD) has predicted that Delhi is poised to experience a significant drop in temperature and rainfall over the next few days due to the impact of a western disturbance. The much-awaited precipitation is likely to be accompanied by a sharp dip in temperature, marking the season’s coldest spell.

As Delhi continues to grapple with winter’s chill, the IMD warns that relief from the biting cold is unlikely anytime soon. After the anticipated rainfall, temperatures in Delhi and its surrounding regions are expected to plunge, with predictions pointing towards a minimum of 2°C in the days following Tuesday.

Weather Update: Rain and Plunging Temperatures

According to the IMD, Delhi’s temperature on Sunday is likely to hover around a maximum of 21°C and a minimum of 10°C. Winds are expected to blow at a speed of 12 to 18 km/h, keeping the fog density moderate. However, Tuesday onwards, the arrival of a western disturbance will bring isolated showers across the capital. The rain will lead to a significant drop in the maximum temperature, which may decline by two degrees.

While Delhi-NCR might experience mild to moderate fog due to active winds, dense fog is predicted in other parts of northern India, including Uttar Pradesh. This will exacerbate cold wave conditions, particularly in regions where winds are stagnant.

Air Quality in Delhi: Grim but Improving

Delhi’s air quality remains a pressing concern despite some improvement in recent days. On Saturday, the city’s average Air Quality Index (AQI) stood at 255, categorized as “poor.” This marks an improvement from Friday’s AQI of 289, as increased wind speeds helped disperse pollutants.

However, the situation is far from ideal. Eleven areas across Delhi recorded AQI levels above 300 on Saturday, placing them in the “very poor” category. Experts warn that residents should brace for continued exposure to suboptimal air quality, as conditions are unlikely to improve significantly over the next two days.

The Central Pollution Control Board (CPCB) attributes the slight improvement to increased wind activity, which has helped reduce the concentration of particulate matter. Nevertheless, the IMD warns that Delhi residents will need to wait longer for truly clean air.

Delhi’s Air Pollution: A Persistent Challenge

The CPCB’s data highlights that pollution levels remain elevated in several parts of the city. While stronger winds have provided some respite, the pollutant dispersal rate may slow again as temperatures drop. The very poor air quality recorded in areas like Jahangirpuri, Anand Vihar, and Rohini is particularly concerning, with AQI levels crossing 300.

Public health experts continue to advise residents, especially vulnerable populations such as children, the elderly, and those with respiratory conditions, to limit outdoor activities during peak pollution hours. The use of N95 masks remains strongly recommended when stepping out.

Impact of Western Disturbances on Delhi-NCR

The western disturbance expected to hit Delhi is a key weather system that typically originates in the Mediterranean region and moves towards the Indian subcontinent. As it approaches northern India, it brings cold winds, rainfall, and a significant drop in temperature. These disturbances are particularly common during winter months and are instrumental in shaping the region’s weather patterns.

With this new disturbance, Delhi is set to witness rainfall in isolated pockets, which will likely reduce particulate pollution temporarily. However, the associated drop in temperature may worsen cold wave conditions across Delhi and adjoining states.

Delhi’s Temperature Trends: What Lies Ahead?

Once the western disturbance subsides, temperatures are expected to drop significantly. Meteorologists predict that Delhi’s minimum temperature could fall as low as 2°C, making it the coldest period of the season. This drop will be accompanied by biting winds, further intensifying the chill factor.

Residents are advised to prepare for extreme cold by layering up, ensuring adequate heating in homes, and taking measures to avoid hypothermia. Those relying on heaters should be mindful of indoor air quality and ensure proper ventilation to prevent the buildup of carbon monoxide.

Dense Fog Expected in Uttar Pradesh and Beyond

While Delhi-NCR braces for light rain and moderate fog, dense to very dense fog is likely to envelop large swathes of Uttar Pradesh, Haryana, and Punjab. The IMD has issued warnings for significantly reduced visibility in these areas, which could disrupt transportation and daily activities.

Drivers and commuters are advised to exercise caution on the roads, especially during early mornings and late evenings when fog is at its densest. Railways and airlines have also been put on alert for potential delays due to reduced visibility.

Pollution and Winter: A Double Threat

Delhi’s residents are battling a dual challenge of severe pollution and an intensifying winter. While the rain may bring temporary relief by reducing particulate matter, the overall improvement in air quality is contingent on sustained efforts to tackle pollution at its source.

The government has been implementing measures like the Graded Response Action Plan (GRAP) to curb emissions during peak pollution periods. However, enforcement and compliance remain critical factors in determining the plan’s success.

How Delhiites Are Coping

The colder weather has led to increased reliance on heating appliances, which, ironically, contributes to the city’s air quality woes due to the combustion of fossil fuels. Awareness campaigns urging residents to adopt cleaner alternatives, such as electric or infrared heaters, have gained momentum.

Meanwhile, Delhi’s hospitals are reporting an uptick in cases of respiratory illnesses, exacerbated by the pollution and cold weather. Doctors recommend staying indoors during peak pollution hours, consuming warm liquids, and wearing masks to minimize exposure.
