NOAA Atlas 14 - California
Example: A 6-hour - 100
Year storm (i.e., 6 consecutive hours of rain) with a return period
of 100 years would statistically be 3.11 inches.
VERY IMPORTANT NOTE: A 100-year storm means that
there is a 1-in-100 probability of a similar event in any given
year. It does NOT mean there is an interval of 100 years
