The probable maximum precipitation (PMP) for stations in Malaysia using Hershfield formula is routinely estimated as mean plus 15 standard deviations processed from yearly maximum rainfall values. The value of 15 as frequency factor is too high for a humid region such as Malaysia. In this paper, yearly maximum 1-day rainfall data of about 30–60 years for 33 stations in the region of Selangor, Malaysia, were analysed in an attempt to estimate PMP for 1-day duration based on an appropriate frequency factor for the first time.
