frequency (PF) estimates in this table are based on frequency analysis of partial duration series (PDS). <br />Numbers in parenthesis are PF estimates at lower and upper bounds of the 90% confidence interval. The probability that precipitation frequency estimates (for a <br />given duration and average recurrence interval) will be greater than the upper bound (or less than the lower bound) is 5%. Estimates at upper bounds are not <br />checked against probable maximum precipitation (PMP) estimates and may be higher than currently valid PMP values. <br />Please refer to NOAA Atlas 14 document for more information. <br />Back to Top <br />PF graphical <br />Precipitation Frequency Data Server http://hdsc.nws.noaa.gov/hdsc/pfds/pfds_printpage.html?lat=37.8736&lo... <br />1 of 4 06/07/2014 11:01 AM
