New Delhi: The weather in the national capital took a sudden turn on Wednesday morning as light drizzle was reported in several areas. Under the influence of a western disturbance, the city is expected to witness cloudy skies and intermittent rainfall through the day, according to the (IMD).

The IMD has issued a yellow alert, forecasting light rain in the morning followed by moderate showers accompanied by thunderstorms in the afternoon. Wind speeds may reach 30-40 kmph at times. Light rainfall is also likely during the evening hours. While the maximum temperature is expected to dip slightly compared to Tuesday, the minimum temperature may see a marginal rise.

Southerly and south-easterly winds are predicted at different intervals throughout the day. The maximum temperature is likely to hover between 26 and 28 degrees Celsius, while the minimum may range from 13 to 15 degrees Celsius.

On Tuesday, the city experienced partly cloudy skies, with brighter sunshine in the afternoon as clouds gradually cleared. The maximum temperature was recorded at 30.9 degrees Celsius - 6.5 degrees above normal - though slightly lower than Monday, which was declared the hottest day of the season. The minimum temperature stood at 12.4 degrees Celsius, 1.4 degrees above normal. Humidity levels peaked at 95 percent.

Slight Improvement in Air Quality
While residents continue to grapple with polluted air, there was marginal relief in pollution levels on Tuesday compared to Monday. According to data from the (CPCB), the average Air Quality Index (AQI) dropped to 249 on Tuesday from 261 on Monday. However, it remained in the ‘very poor’ category at several monitoring stations.

On Monday, 16 monitoring stations recorded AQI levels above 300. By 6 pm Tuesday, seven locations remained in the ‘very poor’ category. For comparison, the AQI was 216 on Sunday.

As per prescribed standards, air is considered healthy when PM10 levels remain below 100 and PM2.5 levels under 60. However, at 5 pm Tuesday, the average PM10 level in Delhi-NCR stood at 224.3 micrograms per cubic meter, while PM2.5 was recorded at 102.3 micrograms per cubic meter - nearly double the safe limits.

With a fresh western disturbance becoming active, residents can expect changing weather conditions over the next 24 hours, though sustained relief from pollution remains uncertain.
