Selecting forecast issue times

Selecting multiple or historical issue times can be helpful to compare forecasts and revisit past flow events. The HydroForecast dashboard enables users to search and view previously issued forecasts.

To make a selection you can either use the shortcuts or use the calendar drop downs (start date and end date respectively) to select a time period of interest. This selected time period will control the x-axis of all plots in the section, and observations will be displayed, when available.

When a date range is selected, a dropdown displays all of the available forecasts, listed by their issue time. There are shortcuts here as well, or you can select forecasts one at a time by clicking the square next to the date-time.

When multiple forecasts are displayed, confidence intervals are hidden for clarity. To show the confidence intervals of a forecast, hover over the circle displayed at its issue time.

Share a forecast! Issue times and date ranges are stored in the URL parameters, so you can share a specific forecast with others in your organization. You can also switch between sites while maintaining your selected date range and forecast issue time.
