The Weather RADAR overlay displays a continuous loop of radar information for the last hour. The feed is refreshed every five minutes. Note: this may lag actual rain by up to approximately 5-10 minutes.
Animated overlays such as this can be played in a loop, paused or stepped forwards/backwards, using the icons on the radar controls. 
These controls appear at the bottom of the map page.
The timestamp for the snapshot is displayed in the bottom-left hand corner. 
You can also select from:
- Infrared Satellite (cloud)
- Surface Pressure Forecast
- Freezing Level Forecast
- Cloud Ceilings Forecast
- Visibility Forecast
