Rain revellers, here’s your September sop.

A low-pressure trough hovering over Odisha and the Bengal coast is promising downpour in Jharkhand. Both Patna Meteorological Centre and the Regional Meteorological Centre in Calcutta have issued heavy rain warning in the next 24 hours.

“Low pressure over the Bay has already resulted in a good spell of rain in most parts of the state since last (Wednesday) evening. Under its influence, several places are likely to experience moderate to heavy rainfall in the next 24 hours,” said A.K. Sen, the director of Patna Met office.

The senior weatherman, however, said that the low-pressure trough, which was moving towards the Odisha coast, would become weak after the next 24 hours. “Weather conditions will improve after a day. But, most parts of Jharkhand will continue to get light rain,” he added.

Weather officials in Calcutta predicted heavy and widespread rain. “The trough will weaken only after the next 24 hours,” said a duty officer at the Alipore Met centre.

The local Met office in Jamshedpur recorded 61.3mm of rain in the last 24 hours, while capital Ranchi recorded 38.4mm. Maharo in Jamtara topped the rain-o-meter with 89.4mm. Hiranpur in Pakur district followed second with 76.5mm. Several other districts like Bokaro, Dhanbad, Khunti, Deoghar, Godda and Lohardaga too have experienced a good spell since Wednesday.

Ghatshila and Galudih in East Singhbhum soaked in around 60mm rain, while several pockets of West Singhbhum and Seraikela-Kharsawan districts received 20mm.

Statistics revealed that the state has so far received 780.4mm rain against a normal of 1,021.4mm, a deficit of 24 per cent.

Weathermen hope rainfall in the next 24 hours will drag down the loss figure by at least three notches.

East Singhbhum tops the seasonal rain chart with 1,126mm against a normal of 987.8mm, a surplus of 14 per cent. Godda too has an impressive rain record of 898mm against a normal of 860.5mm, a surplus of four per cent.

Though Lohardaga, Latehar, Sahebganj and Pakur figure on the deficit list, the shortfall is negligible between three and 10 per cent.

The low pressure, meanwhile, dragged down maximum temperatures several notches below normal in most parts of the state.

Several districts also recorded cent per cent humidity during daytime owing to heavy moisture incursion into the atmosphere.
