The name refers to the Fujita scale of tornado strength, specifically those that produce winds of 261-318 mph.
The National Oceanic and Atmospheric Administration (NOAA) has gone back and reevaluated the records of the damage inflicted by tornados over the years, as measured by the Fujita Scale that came into existence in 1971.
Tornadoes can have winds from 70-200 mph and are rated on the Enhanced Fujita Scale, which estimates wind damage done to structures, cars or the ground.
The National Weather Service assigned an EF3 rating on the enhanced Fujita scale to the tornado, meaning wind speeds reached 136 to 165 miles per hour--making it the strongest tornado to hit Orleans Parish since records began in 1950.
The storm was rated 2 on the five-step Enhanced Fujita scale, with winds of up to 130 mph (210 kph), and there were no reports of damage from the Oceanside tornado.
It was named the Fujita scale, or F-Scale, which was later modified and is now officially called the Enhanced Fujita or EF-Scale (see Page 59).
Facilities are required to offer storm shelters that can protect as many occupants as the building holds from wind speeds of 250 miles per hour--the highest ranking on the Enhanced Fujita Scale.
Both tornadoes were ranked as F4 on the Fujita scale at that time.
The Met Office and TORRO (The Tornado and Storm Research Organisation) estimated that the tornado had a general 'T4' rating on the TORRO scale with a short spell as a 'T5' tornado, which would mean wind speeds between 93 and 130 mph, equivalent to an F2 on the Fujita scale.
