Delay in monsoon pushes rainfall deficiency to 45% in first 9 days of June

The rainfall deficiency in June could be higher due to the sluggish pace of the monsoon and a weak El Niño, a phenomenon associated with heating of Pacific waters

A delay in the arrival of monsoon has pushed the country’s rainfall deficiency in the first nine days of June to 45 per cent, the India Meteorological Department (IMD) said.

Monsoon made an onset over Kerala on June 8, a week after its normal arrival date. This has also delayed its arrival in different parts of the country. The country received only 17.7 millimetres of rainfall as against the normal precipitation of 32.4 millimetres, which comes to around 45 per cent, it said.

The rainfall deficiency in June could be higher due to the sluggish pace of the monsoon and a weak El Niño, a phenomenon associated with heating of Pacific waters.

An on-going cyclonic circulation in the Arabian Sea could slow down the progress of monsoon over the next few days, it said. “A low pressure area has formed over southeast Arabian Sea and Lakshadweep area and east central Arabian Sea. It is very likely to concentrate into a depression during the next 48 hours over southeast and adjoining east central Arabian Sea. It is very likely to move north-northwestwards and intensify further into a cyclonic storm subsequently,” the IMD data said.

Of the four meteorological divisions of the country, the deficiency was 66 per cent — the highest in the country — in central India that covers the states of Maharashtra, Madhya Pradesh, Gujarat, Goa, Odisha and Chhattisgarh. Gujarat and Kutch and Saurashtra sub-divisions of central India have clocked a deficiency of 100 per cent, it said.
