Brace for wet weekend, hope for deficit dip
- Monsoon trough shifts south to trigger rain and thunder alert

Jamshedpur, Aug. 22: An upper air cyclonic circulation coupled with the shifting of the monsoon trough towards the south will result in rainfall activity over Jharkhand in the next 48 hours.

Both Patna and Ranchi Met offices today issued rain and thundershowers alert over the state for the next two days.

“The upper air cyclonic circulation existing up to 2km is stretched between Sikkim and coastal Odisha. This coupled with the axis of monsoon trough, which shifted to Bihar today from the foothills of Himalayas, will result in showers in the state,” said B.K. Mandal, the director of Ranchi Meteorological Centre.

Director of Patna Meteorological Centre A.K. Sen said the axis of monsoon trough would be completely restored over Jharkhand in another three to four days. “We are once again expecting a good spell of rain over Jharkhand around August 26 owing to restoration of the monsoon trough,” he added.

Meanwhile, several areas across the state, including Ranchi, Jamshedpur and Daltonganj, experienced moderate to heavy showers today.

The local weather office in Jamshedpur recorded around 35mm rainfall with the intensity being more towards the evening. The showers were accompanied by lightning and thunder. Weathermen said lightning was caused by the formation of local cumulo-nimbus clouds.

The observatory in Ranchi recorded around 10mm in the past 24 hours while Daltonganj registered 3.5mm. Ghatshila in East Singhbhum and Ramgarh district soaked in over 40mm. Seraikela-Kharsawan recorded around 15mm while Latehar witnessed 20mm. Weather offices in Dhanbad and Deoghar recorded 10mm.

Statistics revealed that the deficit percentage as of today stood at six. Against a normal of 770.4mm, Jharkhand has received 721.1mm so far.

Garhwa tops the list of deprived districts with 45 per ent followed by Ranchi at 40 per cent. The other deficit districts include Lohardaga (37 per cent), Simdega (29 per cent), Palamau (26 per cent) and Dhanbad, Jamtara and Chatra (20 per cent each).

Rain surplus districts include West Singhbhum (44 per cent), Koderma (41 per cent), Deoghar and Hazaribagh (17 per cent each) and East Singhbhum (4 per cent). Showers have been normal in Dumka, Giridih, Godda, Khunti, Ramgarh and Sahebganj.

The total average seasonal rain in Jharkhand is 1,092mm of which 82 per cent takes place between June and September. In 2013, the state had recorded 844.4mm in these four months, resulting in a deficit of 23 per cent while it had ended on a little above normal note the year before.
