Recently Google Maps updated it's maps with new imagery, removing all those areas obfuscated by cloud cover. Presumably they didn't map Skull Island because it's perpetually shrouded by clouds, but wherever a clear image existed it replaced one with clouds, allowing you to view a (presumably) sunnier world.
Which explains the curious patchwork of winter and clouds I found in this image:
The couldn't get all the clouds (Maybe THAT's where King Kong is living), but they got some. Note the curious squares of winter...
