Despite a yellow alert in Delhi, the Capital remained sunny, with mercury rapidly rising through the day.. Rain caused by western disturbance. The rain on Monday took place due to a fresh western disturbance influencing northwest India on Sunday. Another western disturbance is also likely on April 2, with chances of very light rain in Delhi on April 3 and 4.. Palawat said there are chances of rain in Delhi on Monday during the day, before this western disturbance starts to weaken again. He added that a fairly cool start to April was on the cards, saying, “We will then get another western disturbance around April 2 and 3, followed by another between April 6 and 9, so the temperature is unlikely to rise too rapidly.”. Meanwhile, amateur weatherman Navdeep Dahiya said frequent western disturbances are likely to continue next month, with heatwaves to be at bay till the end of April.
