VFR conditions for airport in low visibility
Beja airport (LPBJ) METAR identified as VFR when fog conditions were reported - visibility 200 meters.
Perhaps, as NSC (no significant cloud) was also reported, it triggers the system to identify current conditions as VFR and not LIRF / IFR.
You got it!
NSC can be used if visibility is more than 5km and less than 10km.
