Joplin Tornado Death Toll Mounting

Posted by feww on May 29, 2011

State Authorities Have Trouble Counting?

Missouri state officials said they had positively identified 142 sets of human remains Saturday.

But that was early Saturday. Just a few hours later they changed their minds and revised the figure down to 139,  a report said.

A week has now passed since the deadly EF-5 tornado struck Joplin, Missouri, destroying much of the city.

Data Source: Storm Prediction Center. Tabulation: FIRE-EARTH. *Joplin tornado death toll is preliminary, many are still missing.
1. “Having happened before the era of comprehensive damage surveys, some of these events may have been composed of multiple tornadoes along a damage path. Death counts for events in the 1800s and early 1900s should be treated as estimates since recordkeeping of tornado deaths was erratic back then.” SPC said on its website.
2. Modern recordkeeping did NOT began until 1950.

Joplin Tornado – May 28 Update

Posted by feww on May 28, 2011

Joplin tornado death toll climbs to 132

Death toll from the devastating EF-5 tornado that struck Joplin on May 22 has risen to 132, after the remains of 6 more victims were identified, according to Joplin City Manager.

The twister, the deadliest single tornado to strike in the United States in 64 years, has also injured about 1,000 people.

Meanwhile, the officials said the number of people uncounted for had dropped to 156 [the number of missing was previously stated at about 1,500.]

Official  also said the remains of only 19 of the victims had so far been identified and released to families, a report said.

“Many of the bodies are in such poor condition that officials said they are using fingerprints, medical records, distinctive tattoos, DNA and other methods to identify them.”

Joplin Tornado Radar Animation

A supercell thunderstorm tracked from extreme southeast Kansas into far southwest Missouri (NWS Springfield, County Warning Area) late Sunday afternoon and evening (May 22nd).  This storm produced an EF-5 tornado over Joplin, Missouri resulting in devastating damage. This storm generated other tornadoes and wind damage along its path as it moved southeast across far southwest Missouri.  Spotty wind damage also occurred across the remainder of far southern Missouri as the storms moved east.  Additionally, these storms produced flash flooding across far southwest Missouri.  Image and caption: National Weather Service (NWS)

Joplin tornado store receipt flew 525 miles to Indiana

Meanwhile a Purdue University storm researcher reported that “a receipt from a tire store in Joplin, Mo., turned up 525 miles away on a front porch in north-central Indiana, a record distance for apparent tornado debris to travel,” according to a report.

“This paper traveled more than twice as far as the longest distance recorded for debris from a storm,” according to a professor of earth and atmospheric sciences and tornado expert. “The previous record was a canceled check that traveled 210 miles after the 1915 tornado in Great Bend, Kan.” Said the report.

U-S Tornadoes: Pray for the Dead

Posted by feww on April 30, 2011

Governor Bentley Declares Sunday as a Day of Prayer for the Dead

Governor Robert Bentley signed a proclamation late yesterday calling for a statewide “Day of Prayer” on Sunday, May 1 to remember those who lost their lives in Wednesday’s storms.

“I am asking all people of faith in our state to set aside Sunday as a Day of Prayer in memory of our family, friends, and neighbors who were taken from us in this shared tragedy,” Governor Bentley said.  “It is appropriate that we pray for those we lost, for those who loved them, and for those still suffering.  We all need divine guidance and providence in the days ahead as we seek not only to rebuild, but to heal.”

Bentley has also issued a directive for flags on all state government buildings to fly half-staff until Monday, May 2 at 8:00 a.m.

Tornado and Storm Death Toll in Alabama

At least 238 people lost their lives with more than 1,700 others injured.

Tornado and Storm Death Toll across Southern US

At least 346  deaths have so far been reported across southern United States, including 108 fatalities in Arkansas, Georgia, Kentucky, Louisiana, Mississippi, Tennessee and Virginia.

In Tuscaloosa the death toll has reached 42, but cadaver dogs are brought in to search for more bodies, a report said.

The death toll across the region is expected to rise.

Other Damage

  • Tornadoes and storms have destroyed/damaged at least 10,000 buildings across the devastated areas.
  • An estimated 25,000 people are left homeless.
  • The tornadoes have paralyzed Alabama’s poultry industry, America’s  3rd largest chicken producer.
  • A number of other industries have been severely affected as a result of Wednesday’s tornadoes.

Mega Tornadoes

The National Weather Service said the twister that touched down at Smithville in Monroe County, Mississippi on Wednesday was an EF-5 (F5) tornado, with top winds of 205MPH.

Super-cell T-storms

“These were the most intense super-cell thunderstorms that I think anybody who was out there forecasting has ever seen,” Greg Carbin of the SPC in Oklahoma told the AP.

The twister that destroyed large parts of Tuscaloosa, is also believed to have been an EF-5 tornado [See below for Fujita Pearson Tornado Scale.]

“We have neighborhoods that have been basically removed from the map,” Tuscaloosa mayor Walter Maddox said, describing the damage as a path of ”utter destruction.”

Another large twister, possibly an EF-4 tornado, reportedly destroyed about 90% of the town Hackleburg, in Alabama’s Marion County.

The National Weather Service has confirmed an EF-4 tornado touched down in the Tennessee Valley, a report said.

States of Emergency

Alabama, Arkansas, Indiana, Kentucky, Louisiana, Mississippi, Missouri, Oklahoma, Tennessee and Virginia have declared states of emergency.

Storm Shuts Down 3  TVA Nuclear Reactors at Browns Ferry in Alabama

The 3 reactors at TVA’s 3,297-megawatt Browns Ferry nuclear plant in Alabama, the second largest in the US,  switched over to emergency diesel generators to supply power for the reactors cooling system at 5:30 EDT (22:30 UTC) after storms knocked out  transmission lines that supplied power, the U.S. Nuclear Regulatory Agency said. More…

The tornadoes and violent storms left about a million homes and business without power, mostly in northern Alabama and Mississippi, a report said.

“Roughly 70 high powered transmission lines remain out of service, with some creating dangerous situations because they’ve fallen across roads.”

Browns Ferry nuclear plant won’t restart so long as so much of the grid is down, TVA chief of operations was quoted as saying.

“When the system is ready for the plant, we can begin the process of restarting it. But we have to get the transmission system ready.”

On April 20, a tornado reportedly damaged the switchyard at Dominion’s Surry Nuclear Power Plant (NPP) forcing both aging reactor units to shut down.

F5 and EF5 Tornadoes of the United States – [1950-present]

This is a map and list of tornadoes since 1950 which the National Weather Service has rated F5 (before 2007) or EF5 (equivalent, 2007 onward, the most intense damage category on the Fujita and Enhanced Fujita damage scales. The tornadoes are numbered in the order they happened since 1950; so the numbers run from the bottom up. NOTE: Since the (E)F-scale is a subjective damage assessment tool, official NWS ratings (as logged in Storm Data and in the NSSFC/SPC database) may differ on occasion from those of other tornado databases, such as those of the Tornado Project or University of Chicago.

*** IMPORTANT NOTE ABOUT ENHANCED F-SCALE WINDS: The Enhanced F-scale still is a set of wind estimates (not measurements) based on damage. Its uses three-second gusts estimated at the point of damage based on a judgment of 8 levels of damage to the 28 indicators listed HERE. These estimates vary with height and exposure. Important: The 3 second gust is not the same wind as in standard surface observations. Standard measurements are taken by weather stations in open exposures, using a directly measured, “one minute mile” speed.
