Tornado Risk Calculator

Estimates the relative risk of tornado development based on atmospheric conditions and meteorological data.

Before you use this tool

Use this if

  • Estimates the relative risk of tornado development based on atmospheric conditions and meteorological data.
  • You want a calculation that exposes its formula: Risk Index ≈ (CAPE / 1000) * (Shear / 10) (This is a simplified example. Actual formulas are much more complex.)
  • You already have Location, CAPE (Convective Available Potential Energy), Shear (Wind Shear) values to enter.

Skip this if

  • You need an official emergency alert or life-safety instruction.
  • You need a certified professional forecast instead of a calculator estimate.
