A Cyclonic Circulation is likely to form around July 4 over West Bengal and adjoining Jharkhand and this system is likely to persist for the next three to four days. This would result in increased rain activities in West Bengal. Also, the moisture feed from the Bay of Bengal would help in giving rains which would go on till July 8 or July 9. At present, Gangetic West Bengal is deficit by 58% whereas Sub-Himalayan West Bengal and Sikkim stand at a deficiency of 23%. With upcoming rains, chances are bright that the deficiency levels might come down. The first ten days of July seems to be a promising one in terms of rainfall activities.
