<![CDATA[Not real storm bands]]>There are some storm bands that are not real. For instance in Barcelona - Spain, in the sea. Can it be fixed up?

interfere with wx. radar and produce those non-weather targets (B).

Also, those spikes may refer to "non-weather targets" like:
Solid obstacles such as mountains or buildings,
Ground and sea clutter
Reflections from buildings if the radar is close enough to a city (called urban spikes).

Each of them has their own characteristics that make it possible to distinguish them to the trained eye but they may fool a layman.

This is probably due to interferences with WiFi equipment RLAN, which use the same frequency 5 GHz as the meteorological radars. See a similar problem in the Netherlands:

Not sure that Windy can fix it.
