Other plains of north India that includes Haryana, Punjab, Rajasthan and Uttar Pradesh can also observe similar wet weather conditions.

Meanwhile, monsoon rains will reach the country's southern coast in the first week of June, most probably on 4th. It will deliver less rainfall than average this year, according to a private weather forecaster, lowering the prospects of high farm & economic growth in the Dollar 2.6 trillion economy.
It must be noted that the monsoon rains, which is the livelihood for the nation's farm-dependent economy usually arrive on the southern tip of Kerala around 1st June and move away from Rajasthan by September. Skymet Managing director, Jatin Singh said, "Onset of monsoon will be around 4th June. It seems that early advancement of monsoon over peninsular India is going to be slow”.
