The two graphs indicate the seasonal probablility of specific sized rain events during the 26 year period from 1971-1997. For example, 50% of the rain events in Wilmington were 0.2 inches or less. The graphs for Wilmington and New Bern are quite similar. Both indicate that larger rain events occur during summer and fall than during the winter or spring.

Such information is useful when planning stormwater storage structures. If plans are made to capture the first inch of rain, what percentage of the rain events will be controlled? What percentage of the rain events will exceed the planned storage capacity? How does this differ with season?
