On 23 May 2017, an enhanced Fujita scale 2 (EF2) tornado impacted the coastal islands to the east of Savannah, Georgia.
In a report issued today, Moody's says the monster tornado--rated EF5 on the Enhanced Fujita Scale, with winds of around 200 mph--tracked through both residential and commercial areas of the city, spelling potentially significant losses for both personal and commercial property insurance lines.
Scientists concluded the storm was a rare and extraordinarily powerful type of twister known as an EF5, ranking it at the top of the enhanced Fujita scale used to measure tornado strength.
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.
On the Enhanced Fujita scale that measures a tornado's strength based on the damage it causes, the twister was an EF-5, the highest possible level, said Kelly Pirtle of the National Weather Service's Severe Storms Laboratory.
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.
"They pulled kids out from under cinder blocks without a scratch on them." 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.
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.wunderground.com/blog/JeffMasters/comment.html?entrynum=2412) according to Weather Underground meteorologist Jeff Masters.
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.
They provide an overview of the tornado and its formation and passage across Joplin, as well as details on the demographics of the building stock, then describe the damage in residential buildings, commercial structures, and critical facilities; damage in relation to the Enhanced Fujita Scale; a new design philosophy regarding tornadoes; and recommendations to develop guidelines for tornado-resilient construction.
In February 2007, the Fujita Scale was updated to the "Enhanced Fujita Scale." The new scale takes into account the strengths of different types of construction when assessing a tornado's strength.
