RedSky Weather Radar Quick Start

Initial Screen

RedSky's initial screen shows a map of the United States with many blue dots on it.

Each blue dot represents a National Weather Service Radar site. Touch a blue dot to open up a small info window describing the site. Touch the green play arrow icon to load available radar data for that site. A long press forces the imageset to reload.

The radars are overlayed on a standard Google Map View:

Drag your finger to move around
Double-tap or pinch the screen to zoom in
Reverse pinch to zoom out
Tap a radar site (blue dot) to select it. Press the filmstrip icon to load the animation.
A long press on either load button (US mosaic or filmstrip) forces a reload
