As on August 1, both Bihar and East Uttar Pradesh were 29 per cent rain deficient. Due to subdued rainfall activity in the region during that period, the deficiency continued to increase. On August 10, while Bihar was rain deficient by 34 per cent, East Uttar Pradesh observed a deficiency of 37 per cent.
However, in the last 2 days, good rains were observed over the foothills of the Himalayas, particularly over Bihar. These rains further reduced the rainfall deficiency in Bihar. On August 20, Bihar received a whopping 42 mm of rain against the average 8.2 mm, which is five times more than the normal rainfall. Also, on August 21, the state observed 40 mm of rain, against the average rainfall of 10 mm, which is four times more than the normal rain.
This rainy spell has reduced the rainfall deficiency to 18 per cent in Bihar bringing down the rainfall figures to normal. On the other hand, even though Bihar and Uttar Pradesh lie adjacent to one another, the latter has not received good rainfall and still remains 34 per cent rain deficient.
For the next few days, both Bihar and East Uttar Pradesh will receive scattered rain. The Monsoon trough is presently running close to the foothills which will cause some rainfall activity over the region. While this rainfall may be sufficient on the agricultural front, it may not be able to bring down the rainfall deficiency in East Uttar Pradesh significantly.
