Within a span of 24 hours from 08:30 am on Monday, Daltonganj witnessed 29 mm of rains, Supaul 28.7 mm, Purnea 28.4 mm, Forbesganj 28.2 mm, Muzaffarpur 22.2 mm, Gaya 21 mm, Jamshedpur and Ranchi witnessed light rains of 8 mm and 0.8 mm respectively.
As per Skymet Weather, these rains can be attributed to a cyclonic circulation which is over East Uttar Pradesh and over Sub-Himalayan West Bengal. At present, the axis of Monsoon trough is also running along Uttar Pradesh and Bihar. This trough is likely to shift towards north resulting in rains over both the states. These rains can be moderate to heavy in intensity. One or two extremely heavy downpours cannot be ruled out as well.
Such heavy fall can even result in flash flooding in the low-lying areas and foothills of Bihar. Moreover, as heavy rains are even lashing the neighboring country of Nepal, the possibility is very high that the rainwater from the hills of Nepal may flow downwards towards the foothills of Bihar thus aggravating the flooding situation.
Regions like Bhagalpur, Supaul, Patna, Gaya, Jamshedpur, and Ranchi may receive heavy showers for the next 2-3 days and reel under flood like situation. Despite arousing flood like situation, these rains will beneficial for the sowing of Kharif crop would also contribute in enhancing the prevailing rainfall deficiency that at present both Bihar and Jharkhand are experiencing.
As on July 3, Bihar is rainfall deficient by 34% while Jharkhand is 22% rainfall deficient.
