When it rains, it pours.
The low-pressure trough, which has been drenching Jharkhand for more than 72 hours, will take at least a couple of days to dissipate, weathermen said on Wednesday, indicating that the maverick system may prolong monsoon’s stay in the state.
“The low-pressure zone was hovering over coastal Odisha till last (Tuesday) evening. Today, it has moved to south Chhattisgarh along with an associated cyclonic circulation extending 5.8km up to the mid-troposphere level. The twin systems will result in widespread rain across Jharkhand in the next 48 hours,” said B.N. Chaudhury, a senior analyst at Patna Meteorological Centre.
The Met office has warned of heavy rain at a few places in the next two days. “For the first time this year, monsoon is vigorous in Jharkhand,” Chaudhury added.
The Met department declares “vigorous rainfall” when precipitation is more than four times of the normal.
Rainfall also has to be widespread and at least two Met stations should report 50mm in a day.
Sources said 96 per cent observatories across the state had recorded rainfall in the past 24 hours. Such a rare phenomenon was observed for the first time this monsoon. Many places had received an average rainfall of over 20mm.
Statistics revealed that Hindgir in Ranchi district topped the shower chart with 150mm, followed by Ramgarh that experienced 140mm. Capital Ranchi recorded 130mm, while the observatory at Balumath in Latehar registered 112mm. Kuru in Lohardaga soaked in 104mm.
Several other places such as Panki in Palamau, Daltonganj, Gumla, Khunti and Baharagora in East Singhbhum witnessed downpour since Tuesday evening.
Steel city Jamshedpur was, however, not as lucky. It recorded a little over 30mm in 24 hours.
The Regional Meteorological Centre at Alipore in Calcutta too predicted widespread rain in Jharkhand.
“Low pressure and cyclonic circulation will result in a good spell with heavy rainfall at a few places over the next two days,” said a duty officer.
The rain god’s largesse dragged down the maximum temperature by three to four notches at many places, with further plunge expected in the next 24 hours.
Weathermen in Patna confirmed that the adverse conditions might prolong monsoon’s stay in Jharkhand.
