WSEC, 2006: A recommendation for an enhanced Fujita scale
The storm is thought to have registered a four on what's called the Enhanced Fujita scale
, laying waste to scores of buildings and a community of 41,000 people.
The National Weather Service issued an initial finding that the tornado was an EF-4 on the enhanced Fujita scale
, the second most powerful type of twister.
WITH winds of more than 200mph the Oklahoma tornado measured EF-5 on the Enhanced Fujita scale
, the most powerful.
The National Weather Service upgraded its calculation of the storm's strength on Tuesday, saying it was a rare EF5, the most powerful ranking on the Enhanced Fujita Scale
"I LOOKED UP AND SAW THE TORNADO" The last time a giant twister tore through the area, on May 3, 1999, it killed more than 40 people and destroyed thousands of homes.
Spokeswoman Keli Pirtle said Tuesday the agency upgraded the tornado from an EF-4 on the enhanced Fujita scale
to an EF-5 based on what a damage assessment team saw on the ground.
But depending on the results of damage surveys, this rating could get bumped up to an EF-5, the highest on the Enhanced Fujita scale
that measures tornado strength, (http://www.
The tornado was classified as an EF2 on the Enhanced Fujita Scale
In early August, a category 2 tornado on the Enhanced Fujita scale
touched down in Brooklyn, New York.
On the Enhanced Fujita Scale
, which is a set of wind-speed estimates that goes from 1 to 5 and is based on observed damage, weather experts said the storm that hit Lake County rated a 3 with winds approaching 165 mph.
The Enhanced Fujita Scale
replaces the Fujita Scale, which had been used since 1971.
