Stormy start to new week

- Low pressure, cyclonic circulation to trigger more rain

Benevolence will be the middle name of the rain god for the next two days.

The IMD offices in Patna and Ranchi issued a 48-hour downpour alert in isolated pockets of Jharkhand in their Sunday afternoon bulletins, pointing to a low-pressure trough over the north Bay of Bengal and a cyclonic circulation.

“The low-pressure area, which was hovering over the Bay, has intensified further. An associated storm is also brewing over Jharkhand and its neighbourhood, 1.5km above the sea level. The two favourable weather systems will result in widespread rain over Jharkhand in the next two days. A few places will experience heavy showers,” said A.K. Sen, the director of Patna Meteorological Centre.

On Sunday, the monsoon trough was stretched between Rajasthan and east central Bay of Bengal, passing through Uttar Pradesh, Bihar, Jharkhand and Gangetic Bengal.

The Regional Meteorological Centre at Alipore in Calcutta too predicted heavy rain in the state in the next 48 hours. “Jharkhand is expected to witness uniform rain with downpour in isolated pockets. Bengal will get a good spell for 24 hours while heavy to very heavy rainfall is expected in Odisha for two days,” said the duty officer.

He added that moisture concentration in the atmosphere would increase considerably and that would result in formation of dense rain-bearing clouds. “The prevailing wind pattern is favourable and it is helping in cloudy developments.”

Delightfully drenched so far this July, most parts of the state are expected to experience moderate to heavy rainfall till midweek. Weathermen are also hopeful that the shower sop would diminish the deficiency margin.

Currently, Jharkhand is facing a 12 per cent deficit. Against a normal precipitation of 385.5mm, the state received 340mm till Sunday.

On July 15, the loss percentage was 14.

Parts of the state, including Ranchi, Jamshedpur, Giridih, Deoghar, Bokaro, Simdega and Koderma, have received good rainfall for the last couple of days. Both maximum and minimum readings have come down while morning relative humidity at many places like Jamshedpur has shot up above 95 per cent.
