Have you ever heard the term “TORCON” used on The Weather Channel? Do you know what it means? We’ll give you a hint… Typically you’ll hear this word during springtime when a certain type of weather is present.
TORCON stands for Tornado Condition Index and is used to measure how likely it is that a tornado will form within 50 miles of your location. It’s measured on a scale of 1 to 10, 1 being the lowest risk and 10 being the highest risk. For example, if your area’s TORCON is 3, that means there is a 30% chance a tornado is within 50 miles of you.
The concept of TORCON was created by The Weather Channel’s very own Dr. Greg Forbes. The tool was developed in order to help estimate and communicate the chance of tornadoes developing in certain areas.
Here’s the breakdown of TORCON values (via weather.com):
8+ Very high probability of a tornado
6 – High probability of a tornado
4 – Moderate chance of a tornado nearby, but hail and/or high wind gusts possible
2 – Low chance of a tornado, but hail and/or high wind gusts possible
0 – Near-zero chance of a tornado or a severe thunderstorm
The TORCON index is simple to comprehend and helps communities understand the chance of tornadoes impacting their areas. Watch The Weather Channel this severe season and you will see TORCON being used!
