Plotting positions were compared using Weibull’s and Gringorten’s methods. The daily rainfall data of Pune (plain zone) was analyzed for determination of D-days (D=2, 4, 5, and 6 days) rainfall total. The relationship between one day and D-days rainfall totals in Plain Zone was developed. Weibull’s formula was found better than Gringorten’s formula for plotting positions for the observed data of Pune station. The relationships between one day and D-day annual maximum values of rainfall were found to be exponential in nature for Pune
