Monsoon rains in East India varied in distribution throughout the month of June. For instance, rainfall in Bihar by the end of the month was deficient by 28%, while East Uttar Pradesh observed a deficiency of 12%. The other sub-divisions of Gangetic West Bengal and Sub Himalayan West Bengal also fell short of the monthly average rainfall.
But July came as a huge relief for the region as very good rain is being observed in East India since the start of the month. Rainfall during the initial days was due to a cyclonic circulation over Bihar and adjoining Jharkhand region.
But now, the low pressure area which is lying over West Bengal and adjoining areas of Odisha and Jharkhand is responsible for rain in the region. In fact the cyclonic circulation has merged with the low pressure area due to which more intense activity is being observed.
In a span of 24 hours, from 8:30 am on Wednesday, the Alipore Observatory in Kolkata recorded 35.8 mm of rain. While the AWS (Automatic Weather Station) in Kolkata and Dum Dum recorded 87 mm and 66 mm of rain, respectively. Diamond Harbour and and Jalpaiguri also witnessed 64.4 mm and 41.6 mm of rain, respectively.
During the same period, Gaya in Bihar received 55 mm of rain, while Siwan saw 15 mm of rain. Daltonganj and Ranchi in Jharkhand also recorded 42 mm and 15 mm of rain, respectively.
Odisha is another region in East India where good amounts of rain have been recorded. In a span of 24 hours, from 8:30 am on Wednesday, Sambalpur recorded 65.6 mm of rain. In the same duration Bhawanipatna experienced 32 mm of rain.
According to weathermen at Skymet, active to vigorous monsoon conditions will be observed in East India for next 48 hours. Rainfall in the first 24 hours will be more intense and heavy.
