Settings

On the prediction page, the gear-icon settings button (or pressing s) shows a pop-up dialog that controls some settings:

Speed controls how fast imagery is played when animating; higher is faster.

Scale Speed controls whether to scale the animation Speed by the current image's interval (time span). When checked, the speed will be scaled down by the number of hours the current image spans (for images that span more than an hour).

With this enabled, the animation plays at a constant forecast time rate, even when imagery intervals change within the current displayed range. E.g. when the interval changes from 3 to 6 hours per frame, the animation will slow down by half. With this button unchecked, imagery always plays at a constant image frame rate instead.

End delay controls how long to pause at the end of the animation loop. This is a separate delay to emphasize that the loop is about to restart. Higher indicates a longer delay.

Mode controls how the animation plays the imagery:

• Loop plays from beginning to end.
• Rocker plays from beginning to end, then back to the beginning (in reverse).
• Event rocker is like Rocker, but starts and stops at event time, and rocks each side (after then before) of event time. If no event time is defined, it falls back to Rocker mode.
• Flip just flips between the first and last images.

Use UTC shows times in UTC; when unchecked, the local (browser) timezone is used. Note that using local times can lead to more confusing or verbose tick labels on the imagery slider, as the local time offset may not be an even multiple of the imagery interval. (This setting does not affect the two image timestamps below the imagery slider; they always show both UTC and local time.) Note that proper functioning of this site depends on your local device having the correct date and time set.

Weekdays shows weekdays in the imagery slider tick labels when days are shown; when unchecked, months are shown. The day of month is shown next to both.

Scale map scales the weather map appropriately to where it is placed. On wide displays (e.g. desktop PCs), the map is placed to the right of the GUI controls -- so it will be scaled to fill the viewport vertically, enlarging it without inducing scrolling. On narrow displays (e.g. mobile), the map is placed beneath the controls -- so it will be scaled to be as wide as the controls, to avoid wasted space and tiny buttons. When unchecked, the map is shown at native scale, which varies by provider..

Auto refresh automatically refreshes imagery, as well as updating model runs. This is the default, thus it is generally not necessary to manually refresh the page to keep imagery up-to-date.
