The maverick monsoon seems to be in a hurry to leave Jharkhand this year.
If weathermen are to be believed, the shower show will reduce to a trickle by the beginning of October and the drought-buster southwest current will retreat a week ahead of schedule — and, in all probability, on a deficit note.
Usually, the rain god says his annual adieu in mid-October (see chart) and often overstays his welcome.
“The prevailing monsoon flow indicates early withdrawal. Under normal circumstances, the rains last till October 10 and beyond, but the wind pattern suggests that monsoon won’t last that long this time,” said A.K. Sen, the director of Patna Meteorological Centre.
He added that the monsoon current had already weakened in the Southern Hemisphere.
In India, the flow has been staggering for the past 15 days. IMD officials in New Delhi confirmed that the southwest monsoon had already made an exit from Jammu and Kashmir, Himachal Pradesh, Punjab and some parts of Haryana and Rajasthan.
This year, the rain god had kept its date with Jharkhand, reaching bang on time on June 10. But, currently, only low-pressure troughs and cyclonic circulations are causing maximum precipitation. “The wind pattern is changing. Low pressure and other atmospheric systems originating over the Bay of Bengal is holding the monsoon back in Jharkhand,” Sen explained.
In its 48-hour forecast, both Patna Met office and the Regional Meteorological Centre in Calcutta have promised dry weather in the state.
“Monsoon has become weak over Jharkhand. Only isolated rainfall can be expected for the next two days,” said a duty officer at the Alipore weather office in Calcutta. He, however, did not rule out the possibility of “localised rain concentrated in small areas”.
The rain deficit on Sunday stood at 22 per cent. Against an average normal of 1,037mm, the state has so far received 795.3mm. East Singhbhum and Godda are two districts that figure on the rain gainers’ list, recording 17 per cent and 3 per cent surplus, respectively.
Chatra tops the deficit chart with a shortfall of 51 per cent, followed by Garhwa (42 per cent), Ranchi (38 per cent) and Palamau (34 per cent).
