A low pressure area hovering over coastal Bangladesh and neighbouring West Bengal is likely to trigger heavy to very heavy rainfall over Jharkhand in the next 24 hours, said IMD officials on Thursday.
Weathermen said the low pressure coupled with an associated cyclonic circulation was extending upto the upper tropospheric levels. It is likely to move westwards across West Bengal, Jharkhand and Bihar during the next 48- hours.
"We are expecting heavy to very heavy rainfall ( more than 100 mm in 24 hours ) especially in north eastern and central Jharkhand in next 24 hours due to the impact of the low pressure and an associated cyclonic circulation, which originated from the Bay of Bengal. Another cyclonic circulation was persisting over eastern Uttar Pradesh extending between 1.5 and 4.5 Km above mean sea level which will also assist in rainfall activity over Jharkhand, " said Abhishek Anand, head of Ranchi Meteorological Centre.
The monsoon trough at mean sea level was on Thursday passing through Ferozpur, Rohtak , Aligarh Prayagraj and Daltonganj extending up to 0.9 Km.
The forecast also indicated moderate to heavy rain in isolated pockets of Jharkhand even after the next 24 hours as the monsoon trough was passing through the state.
Meanwhile, several places across the state including Ranchi, Jamshedpur, Hazaribagh, Bokaro, Ramgarh and Koderma witnessed intermittent rains on Thursday.
The local IMD observatory in Jamshedpur on Thursday recorded 21 mm of rain while Ranchi recorded 9 mm.
Statistics revealed that several places including Hazaribagh, Koderma, Sahibganj, Jamtara and Garhwa experienced a good spell of rain during the past 24 hours.
Data revealed that so far after the advent of monsoon Jharkhand actually received 472.5 mm of rain against a normal of 503.2 mm, a deficit of six per cent.
Weathermen said the rainfall during the next 48 hours will help in reducing the rain deficit in Jharkhand.
Overcast sky and rain during the last 24 hours resulted in a dip in day's reading in several districts.
According to Met data, the day reading was hovering between 28 and 30 degree Celsius in most districts across the state during the last two days.
