Today's Question: What are the various severe thunderstorm risk categories and what do they mean?

When severe thunderstorms are possible, the NOAA Storm Prediction Center releases severe weather outlooks based on the potential risk. You might see the FOX 17 Weather Team share these outlooks ahead of potential severe weather events. Below is a breakdown of the various severe thunderstorm risk categories.

The severe thunderstorm risk categories are labeled one through five.

Level one, or the dark green, represents a MARGINAL RISK for severe thunderstorms. This means that if a severe thunderstorm develops, it will likely be isolated. The storm is likely to be limited in duration, coverage, and intensity. There's often a low risk for a tornado.

Level two, or the color yellow, represents a SLIGHT RISK for severe thunderstorms. A level two risk indicates the possibility of scattered severe thunderstorms. While they could still be short-lived, there is a greater likelihood of intensity.

A level three, or the color orange, represents an ENHANCED RISK for severe thunderstorms. A level three risk indicates the possibility of numerous severe thunderstorms. They are likely to be persistent and a few could be intense. A few tornadoes are possible, and there could be several reports of wind damage.

A level four, or the color red, represents a MODERATE RISK for severe thunderstorms. A level four risk indicates the possibility of widespread, long-lived, and intense severe thunderstorms. Strong tornadoes and large hail are possible, along with widespread wind damage.

The highest level, a level five, represents a HIGH RISK for severe thunderstorms. This is represented by the color pink, and it indicates the possibility of widespread, long-lived, and very intense severe thunderstorms. Under a HIGH RISK, a tornado outbreak is possible, along with significant and widespread damage.
