Numbers in parenthesis are PF estimates at lower and upper bounds of the 90% confidence interval. The probability that precipitation frequency estimates (for a given duration and average recurrence interval) will be greater than the upper bound (or less than the lower bound) is 5%. Estimates at upperbounds are not checked against probable maximum precipitation (PMP) estimates and may be higher than currently valid PMP values.
