Jamshedpur, Sept. 10: Brace for hot and humid weather this week with no moderate to heavy rain on the radar in the coming four to five days.

According to Ranchi Meteorological Centre, daytime temperatures will increase steadily in most parts of the state and remain above normal. There will also be no significant change in the weather till the middle of September.

"The southwest monsoon has become weak over Jharkhand as the trough has moved towards the foothills of the Himalayas. This will deprive the state of rains. Several areas may witness light rain owing to a north-south trough stretching from sub-Himalayan Bengal to interior Odisha, but humidity and temperature levels will remain above normal," said Upendra Srivastava, a senior weatherman in Ranchi.

Patna Meteorological Centre, which also keeps tabs on Jharkhand's weather, said the relative humidity would remain at an average of 80 per cent throughout the day in many places. "The monsoon is inactive over Jharkhand and our chart and satellite picture analyses don't show traces of systems at sea that can trigger a big change," a duty officer said.

An active monsoon trough had ensured a good spell of rainfall in the state during the first week of this month. Statistics reveal that the state has so far registered 884.6mm against an average normal of 947.2mm, a deficit of 7 per cent.

Data show that only one Met observatory - Nandadih in Koderma district - had experienced rainfall in the last 24 hours. It recorded 9.5mm. Light rain and thundershowers was also reported from a few isolated places since Saturday.

Garhwa tops the rain-defi-cit list with 53 per cent. Other districts include Godda (28 per cent), Giridih (27 per cent), Chatra (25 per cent), West Singhbhum (24 per cent), Jamtara (20 per cent), Gumla (15 per cent), Palamau (13 per cent), Koderma (11 per cent), Deoghar (10 per cent), Dhanbad (7 per cent), Ranchi (5 per cent) and Seraikela-Kharsawan (1 per cent).

The remaining 11 districts, including East Singhbhum (41 per cent), Hazaribagh (9 per cent) and Bokaro (8 per cent), still enjoy surplus status.

Met officials said the monsoon trough had shifted twice this month. A change in the wind pattern is one of the major reasons behind the drift. At present, the westerly wind is dominant over Jharkhand, which won't help in the revival of the monsoon trough.
