What is the GFA symbol indicating the presence of light precipitation in the form of rain or snow?

The symbol indicating the presence of light precipitation in the form of rain or snow on a Government Flight Information (GFA) chart is specifically associated with thunder showers. Thunder showers usually imply a combination of moderate to heavy precipitation, which could include rain or snow in certain contexts. While it may seem somewhat counterintuitive, the choice encapsulates a broader category of precipitation that includes lighter forms.

In GFA charts, different symbols represent various weather phenomena, such as icing or turbulence. Icing is represented by a different symbol that suggests the potential for ice accumulation. Similarly, turbulence has its own distinct symbol indicating areas where aircraft might experience bumpy conditions. The clear type symbol, on the other hand, indicates areas free from significant weather-related phenomena. Thus, these other choices do not align with the representation of light precipitation.
