Monsoon in East India, which spanned across the month of June, assumed unequal distribution of rainfall. For instance, Bihar recorded a deficit of rainfall by 28% at the end of the month. Further, rainfall in Uttar Pradesh took the tumble by 12%. In addition, the other sub-divisions of Sub Himalayan West Bengal and Gangetic West Bengal got behind with monthly average rainfall. However, the month of July was the harbinger of much-needed succor for the region as bucketing rain in East India ensued since start of the month. Also, rainfall during the initial days was touched off by a cyclonic circulation over Bihar and bordering region of Jharkhand.

Low Pressure Area and its Implications

The low pressure area, hovering over West Bengal and other areas of Odisha and Jharkhand, situated in close proximity to West Bengal, laid the path for rain in the region. As a matter of fact, the cyclonic circulation has cut across the low pressure area, which has paved the way for more intense activity in the region.

Irregular Behavioral Pattern of Monsoon in East India

Over a course of 24 hours, from 8:30 AM on Wednesday, 35.8 mm of rain was recorded in the Alipore Observatory in Kolkata. Further, the Automatic Weather Station in Dum Dum and Kolkata witnessed 66mm and 87mm of rainfall, respectively. On the other hand, Jalpaiguri and Diamond Harbour encountered 41.6 mm and 64.4 mm of rainfall, respectively. Further, it tied in with 55 mm of rain lashed down in Gaya, Bihar. Also, Siwan encountered 15 mm of rain. In addition, Ranchi and Daltonganj in Jharkhand witnessed 15 mm and 42 mm of rainfall respectively.

Likely Future Course of Action for Monsoon

Odisha, a region in East India, also recorded a good amount of rainfall. Across a period of 24 hours, from 8:30 AM on Wednesday, 65.6 mm of rain was observed in Sambalpur and 32 mm of rainfall in Bhawanipatna coincided with it. As Skymet got it across, recent weather conditions would usher in active to torrential monsoon in East India for next 24 hours. Further, rainfall in the first 24 hours will be rather overwhelming and intense.
