Rain, hailstorm lash Delhi, NCR, brings down air pollution levels

  • A fresh Western Disturbance is likely to affect Western Himalayan region and plains of north-western India after 10th February
  • The air quality is likely to remain at ‘moderate’ levels on Friday as well

NEW DELHI: Chilly winds coupled with moderate rain and hailstorm swept across the National Capital Region (NCR), improving the air quality levels from ‘very poor’ to ‘moderate’, here on Thursday.

The India Meteorological Department (IMD) had predicted an intense wet spell over the north-western states following a western disturbance which was initially located over Afghanistan and neighbourhood. Along with this, an anti-cyclonic circulation developed over central India which shifted eastwards into the Bay of Bengal.

Both the streams converged over central India bringing moisture over to northwest India from Arabian Sea and Bay of Bengal, respectively. The weather activity remained at its peak on 6 and 7 February bringing heavy rainfall/snowfall over entire northwest India.

“Active western disturbances are known to bring scattered hailstorm, so it is nothing unusual. However, the intensity was high, which was evident especially in Noida, where road stretches upto 3 kms could be seen covered with hailstones. There was widespread rain across Delhi too," said Kuldeep Srivastava, Head, Regional Weather Forecasting Centre, Delhi.

It has been raining intermittently in Delhi since Wednesday evening, however, the rainfall intensified late night on Thursday and later in the afternoon. The maximum temperatures were recorded at 25 °C, while the minimum was recorded at 12 °C. The night temperatures are also likely to fall by 4 to 5 °C from Friday onwards.

As per the forecast, the conditions would persist for next few hours, after which the rainfall would subsequently decrease. The weather department officials sated that the induced cyclonic circulation over north Rajasthan and neighborhood persists, but it would move over to Punjab and adjoining Haryana within next 24 hours.

"There could be light to moderate showers at isolated places, but no heavy rains are expected, as the system would begin to weaken," said Srivastava.

The air quality is likely to remain at ‘moderate’ levels on Friday as well, after which it could start deteriorating, as per the forecast.

“The south-westerly winds from the Arabian Sea will bring more moisture and foggy conditions may occur for next few days. After the passing of the system, the wind speed would reduce, which could deteriorate the air quality levels to ‘very poor’," read the forecast issued by System of Air Quality and Weather Forecasting (SAFAR).

A fresh Western Disturbance is likely to affect Western Himalayan region and plains of north-western India after 10th February, as per IMD.
