Many pilots are taught to strictly avoid what is known as virga. Virga is created when precipitation in the form of rain or snow falling out of the base of a cloud evaporates in a dry atmosphere before reaching the surface. It has a wispy appearance hanging from the base of the cloud when viewed from a distance. Virga that occurs outside of convective activity is very common and ordinarily quite harmless. However, when there’s deep, moist convection in the vicinity, virga may sound the alarm for the potential of moderate or greater turbulence, strong downdrafts and the possibility of microbursts. This workshop will show you how to recognize an environment that may produce virga that is dangerous and should be avoided.
