The Map provides an effective way to visualize the magnitude and impacts of coastal flooding within the Chesapeake Bay and along Virginia's Eastern Shore. The data are generated in 36 hour forecasts each morning and evening. The display is updated twice daily and will show either 6am to 6pm the following day OR 6pm to 6am the day after tomorrow. You can "click" through the display using the arrows on the right end of the slide bar at the bottom of the map, or automate the display by clicking on the arrow on the left of the slide bar.
The Map also contains a charting tool. Click anywhere in the analysis extent to display a chart with two lines: one showing water elevation over the next 36 hours at that location and the other showing the land elevation at that location. This enables the user to quickly estimate when and to what degree flooding will occur at a given location.
