The Low-level significant weather chart (Low-Level SWC) is a forecast chart for flight preparation and planning in General aviation. It describes weather situation over central Europe for a defined time. Therefore, areas with significant weather phenomena are highlighted. Symbols for surface pressure centers, wind maxima, areas with turbulence and icing as well as surface fronts and their movement are displayed. Additionally the chart contains information concerning freezing levels, surface visibility, significant clouds and warnings with regard to radioactive sources and volcanic activities.

LLSWCs do not display radar echoes of precipitation. Airborne weather radar detects drops of precipitation (such as rain/snow/hail).
