Notes
- In the Rain/Flood event step of the Water Overlay Wizard, the area where the configured rain falls can be adjusted. By default, the configured rainfall is equal for each grid cell in the project area. However, when the option Override specified Areas is chosen, the Rain Areas step is added to the wizard, which lets you configure how to identify the Rain Areas. Rain Areas override the weather's rainfall with their specific rainfall.
