Onset of Monsoon was well before time over Andaman Sea as well as over Kerala. The progress of monsoon was satisfactory over West coast of the country. However, the eastern arm of monsoon lagged. Until now, Monsoon has not reached East Uttar Pradesh.
Westerly dry and hot winds are blowing across Northwest India and parts of Central India. These winds are not allowing monsoon to progress further. Weather of Western Himalayas, Punjab, Haryana, Delhi, most parts of Uttar Pradesh as well as Rajasthan northern parts of Madhya Pradesh and North Gujarat has gone dry. Temperatures are also increasing over these states. However, we do not expect heat wave to make a comeback now.
Normal date of onset of Monsoon over Delhi is around June 27th. We expect monsoon rains to revive once again by June 27 or 28. A Trough is expected to develop over Northern Plains leading to humid easterly winds from Bay of Bengal.
The increased moisture will certainly lead to formation of clouds and subsequent rainfall. Post June 28, Monsoon is expected to make a steady progress and will cover parts of Uttarakhand, Uttar Pradesh, Delhi and Eastern parts of Punjab and Haryana by end of the June.
Delhi is going to miss the onset date of Monsoon but the delay will not be significant. Temperatures will subside over Northwest and Central India, giving significant relief from ongoing hot weather conditions.
