Bihar and Uttar Pradesh have not witnessed any rains since last 2 to 3 days and the weather has been almost dry. However, the month of June had been satisfactory in terms of rains for both the states.
As on June 29, Bihar was deficient by 17 percent than its normal while East Uttar Pradesh rains were 22 percent deficient than its normal. On the other hand, rain deficiency for East Uttar Pradesh was merely 7 percent as compared to its normal rains.
Reason for this sudden decrease in rain intensity can be attributed to development of a low pressure area over west central Bay of Bengal around 28 June. Due to this weather system, the wind flow of moderate easterly winds got restricted over East India particularly Uttar Pradesh and Bihar which caused the rains to decrease over the states.
Now, this weather system has diffused but another low pressure area has developed over west central Bay of Bengal although it’s not that strong enough to have any major impact on the weather activities of Uttar Pradesh and Bihar.
The trough is expected to shift towards North and it will, in turn, enhance the rains over the above said states from evening of July 1. However, rain intensity over eastern parts of Uttar Pradesh will be much more as compared to that of Bihar.
By July 2, most parts of Uttar Pradesh will also start receiving heavy to very heavy rains that are likely to continue till July 6. But these rains will be patchy in nature and not continuous. Places like Balia, Azamgarh, Gorakhpur, Basti, Kushinagar, Sultanpur and Amethi may receive some very heavy rainy spells.
Therefore, it can be said that July will start with a heavy bang over Indo Gangetic plains of Uttar Pradesh and Bihar. The rain deficiency is likely to drop for these two states in the first week of July.
Since heavy rains are also predicted over Nepal hills, the foothills of Uttar Pradesh and Bihar may witness flood like situations or water logging. The districts of Uttar Pradesh that are more likely to get affected due to flood like situation include Bahraich, Balrampur and Siddharthnagar, Shravasti, Maharajganj. A few districts of Bihar also seem under danger of flood like situations. These areas include Bettia, Motihari and Sitamarhi.
