Storm Prediction Center worked with various NWS offices, social scientists, communication specialists, the Federal Emergency Management Agency, forecasters, and the general public to produce charts below.
Susan Jasko, a professor of communication at California University in Pennsylvania who provided feedback on this effort thinks the graphic is visually clean which will help people get accustomed to the language of NWS Storm Prediction Center.
In particular, I like about this graphic:
* It describes the various thunderstorm risk levels and the hazards associated with them, all in one place.
* It ranks the risk levels according to numbers on a 1-5 scale in a similar manner to hurricanes. This is helpful for quickly and simply communicating the severity of the thunderstorm risk.
* The colors in the graphic correspond with the colors used to convey risk in severe weather outlook maps
* The graphic provides a sense for the coverage and duration of thunderstorms associated with the different risk levels
