ABSTRACT:
The present invention comprises a wind speed indicating device wherein a plurality of panels of flexible fabric are attached to a vertically disposable holding component. Each panel of flexible material is heavier or more wind resistant than the one above it, thus requiring a higher wind necessary to unfurl it or extend it horizontally. Each panel has markings on its side to indicate the wind speed required to effectuate its unfurling.
