Tornado Ratings - !!hot!!
Tornado ratings are essential for quantifying the intensity and danger of these atmospheric events. Because direct wind speed measurements are rarely possible within a tornado's core, ratings are primarily determined by forensic analysis of the damage left behind. I. The Evolution of Rating Scales
National Weather Service (NWS) survey teams deployed immediately after a major event follow strict procedures to assign an official rating:
Professionals check for construction flaws, such as missing anchor bolts or poor strapping, which can artificially downgrade or upgrade a rating.
A tornado that sweeps away a flimsy barn might only be rated an EF-2 or EF-3. A tornado that sweeps away a fortified concrete structure might be rated an EF-5. It is no longer just about the debris; it is about the construction quality.
