A Study of Heavy Rainfall of 8-10 June, 1991 over Maharashtra, India

A low pressure system from the southwest Bay or Bengal between 8-10 June, 1991 brought heavy and continu-ous rainfall over different parts of Maharashtra. This 3-day heavy rainspell over Maharashtra has been analysed to assess its magnitudes or point as well as areal rainfall. The analysis showed that there were 74 stations which received 3-day total rainfall during 8-10 June exceeding their respective normal June rainfall. The areal raindepths obtained from the rainstorm of June, 1991 have been compared with similar data of past severe rainstorms of the region which showed that June, 1991 rainstorm yielded higher magnitudes of raindepths upto certain size of areas. A relationship has also been developed between point to areal rainfall of this rainstorm for 1-3 day durations for obtaining areal raindepths.
