CFN now supports overlays for the various forecast map types.

1. Select the base layer by selecting any map type.

2. Click on the padlock icon of any other type to overlay it on top as a 50% transparency blend.

There are many possible combinations so experiment.

You can still change location, map time, map type of the underlying map or even the forecast model on the fly (GFS/ACCESS). All touch functionality is preserved.

To change the overlay type to another map click on the padlock of any other button. To go back to the normal viewing click again on the golden padlock to disable it.

Blending the two maps is easier than flicking back and forth between them and you can change the time while still in blend mode.

As an example, the illustration shows a blend of the Surface Wind with the Jet stream Map overlay that could be an indication of the seeing forecast. The areas of good seeing are blue and darker with shorter wind vectors.
