The buttons on the left hand side will move the map to the appropriate WSR station. It is possible to click and drag the map although this action may be slow due to the amount of data being processed.
The background scripts use the HTML5 canvas capabilities of Javascript which may not work on your browser. Map features or the map itself may not appear. It seems to work on Firefox and Chrome, but not on Internet Explorer.
