Some regions in Delhi received light rain on Tuesday, with the weather department predicting cloudy skies and moderate showers on Wednesday and Thursday, PTI reported. The maximum temperature in Delhi settled at 41.5 degrees Celsius on Tuesday, four notches above normal, according to IMD. The minimum temperature was recorded at 30.8 degrees Celsius, three notches above normal.


On Tuesday, ITO, Mandi House, Tilak Marg, Ring Road, DDU Marg, Vikas Marg and Laxmi Nagar witnessed light rainfall. The relative humidity at 5.30 pm was 57 per cent, the IMD said.


In the next two days, Delhi is likly to witness generally cloudy skies and moderate rains. "The maximum and minimum temperatures on Wednesday will hover around 42 degrees Celsius and 30 degrees Celsius respectively," PTI quoted an IMD official as saying.


The IMD said conditions were becoming favourable for the onset of monsoon in north-west India, including Delhi.


"Conditions would continue to become favourable for further advance of monsoon into remaining parts of Arabian Sea and Gujarat, some parts of Rajasthan, remaining parts of Madhya Pradesh, entire Uttar Pradesh and Uttarakhand, Himachal Pradesh and Jammu and Kashmir, some parts of Punjab, Haryana and Chandigarh and entire Delhi during subsequent 48 hours between June 30 and July 1," the IMD said.


Weather experts said Delhi would receive a fresh spell of rain from Wednesday, PTI reported. Monsoon is expected to yield good rainfall in the first 10 days, experts said.


Meanwhile, Delhi authorities said elaborate plans were in place to prevent waterlogging in the newly opened Pragati Maidan tunnel. The tunnel allows commuters travelling to India Gate and other central Delhi areas from east Delhi, Noida and Ghaziabad to ditch traffic snarls at ITO, Mathura Road, Ring Road and Bhairon Marg.


"There is no need to worry about flooding in the tunnel as automatic pumps along with underground sumps have been constructed in the facility. This will enable swift discharge of storm water in case of heavy rain. Other than this, temporary pumps will also be kept on standby mode so that they can be quickly deployed whenever required," a senior PWD official told PTI.
