New Delhi, June 27

The monsoon that arrived three days before its designated onset day over Kerala this year, may miss its June-29 date with Delhi. IMD director-general Ajit Tyagi confirmed to The Tribune today that country’s most awaited seasonal rains were lagging behind schedule. Currently the northern limit of monsoon was passing through Rajkot, Ahmedabad, Indore, Seoni, Pendra, Ambikapur, Daltonganj, Gaya, Muzaffarpur and Raxaul.

“Current indications are that there may be a delay in arrival of monsoon over Delhi. Even though a fresh system developed last week, due to its low intensity the northern limit of monsoon saw no significant movement. By tomorrow, the IMD should be able to predict when the rains will arrive over Delhi and rest of the northwest India,” he said.

Though dates are only said to be pointers, but as per the current system around June 29, 30 and July 1, the monsoon limit is supposed to pass through Punjab, Haryana, Himachal Pradesh and Jammu and Kashmir. The good news was that even though there has been a slight delay in the progress of the monsoon, the country could expect good rains this year that would help it tide over last year’s deficit.

The Met office has predicted monsoon rains this year to be 102 per cent of the long period average, which was an extremely positive sign for the country’s agriculture-driven economy. The northwest India, comprising Punjab, Haryana, Chandigarh, Delhi, UP, Jammu and Kashmir, HP and Rajasthan, was also likely to get good rains this year, as per the IMD.

The weather office that was in the process of reviewing onset dates of the monsoon said as per current dates the seasonal rains cover the entire country by July 15. Weather scientists are in the process of reviewing normal onset dates for monsoon, which may come into effect from next season, said Tyagi.

However, the new dates may vary from the present ones only by a couple of days and would also be subject to a variation of plus or minus seven to eight days. Which means that even though Kerala, Delhi and other parts of the country would soon have new onset dates for monsoon, there may not really be any significant change from current normal dates.

Under normal conditions, southwest monsoon sets in over Andaman seas by mid-May. Under the current system, June 1 was considered the normal date for the onset of the monsoons over Kerala.

Its onward surge begins with Kochi getting rains by June 2, followed by Mangalore (June 3), Vishakhapattanam (June 8), Mumbai, Nagpur, Raipur, Ranchi (June 10), Varanasi (June 15), Lucknow (June 18) and Delhi (June 29). This year, while Kerala saw the onset of monsoon before time, cyclonic storm Phet in the Arabian Sea delayed its advancement across the west coast by about one week.
