Australian Weather Map
There is something strangely exciting about watching an animation of current precipitation over the satellite view of Uluru or the Sydney Opera House. Thanks to this Weather Chaser Google Maps mashup you can now view Doppler radar animation loops for the whole of Australia.
The map also shows the current wind direction and wind strength for the whole of the country. Clicking on any of the wind observation map markers opens an information window displaying the temperature and rainfall at that location.
