When Canada coverage is not available and Canada radar is available,
the Canada weather depiction is rendered as if all Canadian radar sites
are valid.
Areas without radar coverage are displayed with a transparent gray
color when the NXRD bezel softkey label is active, as shown in
Figure 10--9.
NOTE: The convective weather product screen does not display
echo tops or cloud tops to avoid confusion with the gray areas
of no coverage with either weather option.
