The daily rainfall data of Pune (plain zone) were analyzed for determination of D-days (D=2, 4, 5, and 6 days) rainfall total. Plotting positions were compared using Weibull’s and Gringorten’s formulae. 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.
