A tornado warning is a steady, high pitched tone; flash flood is an alternating high-low signal; the attack is an unbroken, wavering signal.
What measurement is used to indicate the severity of a tornado?
The Fujita, or F-Scale, was developed in 1971 by T. Theodore Fujita of the University of Chicago.The original scale was updated in 2007. The updated scale, known as the Enhanced F-Scale, is set of wind-speed estimates - not measurements - based on damage surveys. Its estimates at the point of damage are based on a judgement of eight levels of damage indicators.
The Enhanced F-Scale:
- EF Number 0, 65-85 mph
- EF Number 1, 86-110 mph
- EF Number 2, 111-135 mph
- EF Number 3, 136-165 mph
- EF Number 4, 166-200 mph
- EF Number 5, Over 200 mph
The original F-Scale:
- F-0 (Gale tornado) 40-72 mph
- F-1 (Moderate tornado) 73-112 mph
- F-2 (Significant tornado) 113-157
- F-3 (Severe tornado) 158-206 mph
- F-4 (Devastating tornado) 207-260 mph
- F-5 (Incredible tornado) 261-318 mph
- F-6 (Inconceivable tornado) 319 - 379 mph
