The national capital Delhi has been reeling under the longest heat wave session in the Monsoon season due to the prolonged dry period beginning June 1 to June 13. This has made Delhi the driest city in the country with its cumulative rainfall deficiency mounting to 100%.
On June 10, Delhi’s Safdarjung Observatory recorded 45.6°C as the day temperature. And on June 13, the mercury dropped to settle at 41°C. Today, a marginal rise in temperature can be observed. However, June 15 onward the temperatures will see a downward trend, dropping to 40 degrees Celsius in the coming days.
The reason for these intermittent rains and thundershowers will be the successive yet feeble Western Disturbances which might induce a Cyclonic Circulation over Central Pakistan and adjoining Punjab and Haryana. Moreover, humid strong winds in the area are also pulling moisture from the Arabian Sea, while a trough is extending from Central Pakistan up to East India across Punjab, Haryana and Uttar Pradesh.
The combined effect of these weather systems would be responsible for rain in the region. Dust storm along with rain and thundershowers will be a sight in parts of Delhi and and its adjoining areas like Noida, Ghaziabad, Faridabad, Gurugram. The activities will be light and patchy in nature. However, one or two intense spells for a short duration due to the convective clouds cannot be ruled out.
From June 15 to June 19, these on and off rain, thundershower and dust storm activities would continue over the NCR region.
