1 Precipitation frequency(PF)estimates in this table are based on frequency analysis of partial duration series(PDS).
Num hers in parenthesis are PF estimates at lower and upper bounds of the 90%confidence interval.The probability that precipitation frequency estim des(for
a given duration and average recurrence interval)will be greater than the upper bound(or less than the lower bound)is 5%.Estim des at upper bounds are not
checked against probable m acim trn precipitation(PM P)estimates and m ay be higher than currently valid PM Pvalues.
Please refer to NO PA Atlas 14 docum eit form cre information.
