Severe Wind Threat Level

Threat Level Descriptions

Extreme

"An Extreme Threat to Life and Property from Severe Wind Gusts Associated with Thunderstorms."

Within 12 miles of a location, an extreme likelihood (36% or greater) of severe wind, with storms capable of damaging wind gusts (greater than or equal to 58 mph) causing minor damage to major damage in the worst situations. 

High

"A High Threat to Life and Property from Severe Wind Gusts Associated with Thunderstorms."

Within 12 miles of a location, a high likelihood (26% to 35% probability) of severe wind, with storms capable of damaging wind gusts (greater than or equal to 58 mph) causing minor damage to major damage in the worst situations.  

Moderate

"A Moderate Threat to Life and Property from Severe Wind Gusts Associated with Thunderstorms."

Within 12 miles of a location, a moderate likelihood (16% to 25% probability) of severe wind, with storms capable of damaging wind gusts (greater than or equal to 58 mph) causing minor damage to major damage in the worst situations.   

Low

"A Low Threat to Life and Property from Severe Wind Gusts Associated with Thunderstorms."

Within 12 miles of a location, a low likelihood (6% to 15% probability) of severe wind, with storms capable of damaging wind gusts (greater than or equal to 58 mph) causing minor damage to major damage in the worst situations.    

Very Low
"A Very Low Threat to Life and Property from Severe Wind Gusts Associated with Thunderstorms."

Within 12 miles of a location, a very low likelihood (2% to 5%) of strong wind gusts (greater than or equal to 58 mph) causing minor damage to major damage in the worst situations.

Non-Threatening
"No Discernable Threat to Life and Property from Severe Wind Gusts Associated with Thunderstorms."

Within 12 miles of a location, environmental conditions do not support the occurrence of severe wind gusts from thunderstorms.     

Note: To be considered severe, associated wind gusts must be 58 mph or greater (50 knots or greater).

Damaging Wind Gusts - Severe thunderstorm wind gusts between 58 mph and 74 mph (between 50 knots and 64 knots) causing minor damage, to severe damage with wind gusts of 90 to 150 mph (78 to 130 knots).
