Only southern Norway and the two images are not identical. Two sources that are out of registration maybe?

Looks like there might be a problem with the precipitation radar overlay for Norway. The image appears to be doubled, perhaps a delayed copy of the data? I don't see the same problem on yr.no. Screenshots below:

Ivo's note: this was already fixed so code below is not necessary.

Leaflet 1.4 CSS codes contain serious BUG that we have fixed in our CSS build. So please do not include Leaflet's CSS to your html.

Thanks for all your efforts updating the API!

I found that, after switching to Leaflet v1.4.0, I now need to reference the Leaflet CSS, otherwise the URLs of marker icons are wrong, and the markers do not render correctly. I just needed to add one line in the header of my page:

< link rel="stylesheet" href="https://unpkg.com/leaflet@1.4.0/dist/leaflet.css" >
