It is helpful for, even the experienced, storm
spotter to see examples of cloud formations in order to accurately report the
type of weather conditions that are being observed. NOAA has a very good
library of images available for any person to access and review. Presented
here are a few of the more common types of cloud formations.

Vortex-99. An occluded mesocyclone tornado rated an F3 by an NWS damage
survey. Occluded means old circulation on a storm; this tornado was
forming while the new circulation was beginning to form the tornadoes
which preceeded the F5 Oklahoma City tornado. Photo #1 of sequence.
