WU has completely changed the regional radar maps to have a lot more specificity (centering on a home radar site in the area). I’m still looking at options (including NWS Regional loops as a replacement). WU has become much more trouble than it’s worth, and I’m also strongly considering dropping WU-radar for the Base-USA as they’re still offering the static/animated radar displays but have largely discontinued other regional maps we’ve been using in that script and for the home page mini-displays.
The forthcoming update will likely be somewhat disruptive to existing sites as it will require changes in Settings.php, wxindex.php and flyout-menu.xml which will have to be copied to your existing site files.
Still working on it...
