The Storm Prediction Center in Normal, OK uses a five-category system to clearly communicate the overall severe weather threat, ranging from a Level 1, Marginal Risk to a Level 5, High Risk.
These represent the expected intensity as well as how widespread the impacts may become.
Marginal Risk (Green): Isolated severe storms are possible. Widespread severe weather is unlikely.
Slight Risk (Yellow): Scattered severe storms are possible. Storms will be a tad bit more organized and may produce all severe hazards.
Enhanced Risk (Orange): Numerous severe storms are expected with a greater concentration of damaging winds, large hail, and a few tornadoes. More of a substantial threat.
Moderate Risk (Red): Typically reserved for significant severe weather outbreaks. This includes the potential strong tornadoes (EF-3+), widespread damaging winds, or very large hail. Storms in nature will be more intense and long-lived.
High Risk (Pink): A level 5 high risk is rare but we've seen a few of them in previous years. In fact, part of the Quad Cities viewing area was under a high risk back in March 2023. This includes the potential for long-track,violent tornadoes as well as widespread destructive winds.
