Dark Green – Marginal risk - An area of severe storms of limited organization and longevity.
Yellow - Slight risk - An area of severe storms which is not widespread in coverage and varying levels of intensity.
Orange – Enhanced risk - An area of greater severe storm coverage with varying levels of intensity.
Red – Moderate risk - An area where widespread severe weather with several tornadoes and/or numerous severe thunderstorms is likely. This risk is usually reserved for days with several supercells producing intense tornadoes and/or very large hail.
Magenta - High risk - An area where a severe weather outbreak is expected from either numerous intense and long-tracked tornadoes or a long-lived thunderstorm complex that produces hurricane-force wind gusts and widespread damage.
