Browse structure types from small barns and family residences to high-rise buildings, transmission lines, and trees. Compare what you see against reference photos and construction details, then pick a degree of damage and tune the wind speed estimate between its bounds to account for construction quality. • All 28 damage indicators of the Enhanced Fujita scale • Reference photos and construction details for every indicator • Degrees of damage with expected wind speeds and EF ratings • Interactive wind speed estimator with adjustable bounds • EF0–EF5 rating reference, always a tap away • Everything stored on device — works fully offline in the field Built for storm spotters, damage surveyors, emergency managers, students, and weather enthusiasts. *** PLEASE REMEMBER: This app is for reference purposes only.
