Tornadoes, storms rip US South, at least 284 dead

TUSCALOOSA, Ala., (Reuters) – Tornadoes and  violent storms ripped through seven southern U.S. states,  killing at least 284 people in the country’s deadliest series  of twisters in nearly four decades.
The clusters of powerful tornadoes — more than 160  reported in total — combined with storms to cut a swath of  destruction heading west to east over several days. In some  areas, whole neighborhoods were flattened, cars flipped over  and trees and power lines felled, leaving tangled wreckage.
Given the apparent scale of the destruction, insurance  experts were wary today of estimating damage costs, but  believed they would run into the billions of dollars, with the  worst impacts concentrated in the Alabama cities of Tuscaloosa  and Birmingham.
“In terms of the ground-up damage and quite possibly the  insured damage, this event will be of historic proportions,”  Jose Miranda, an executive with the catastrophe risk modeling  firm EQECAT, told Reuters.
At least 184 people died in Alabama, the worst-hit state  which suffered “massive destruction of property,” Governor  Robert Bentley said.
The mile (1.6 km)-wide monster twister that on Wednesday  tore through the town of Tuscaloosa, home to the University of  Alabama, may have been the biggest ever to hit the state,  AccuWeather.com meteorologist Josh Nagelberg.
Many people told tales of narrow misses. “I made it. I got  in a closet, put a pillow over my face and held on for dear  life because it started sucking me up,” said Angela Smith of  Tuscaloosa, whose neighbor was killed.
President Barack Obama said he will visit Alabama on Friday  to view damage and meet the governor. Obama declared a state of  emergency for Alabama and ordered federal aid.
In preliminary estimates, other state officials reported 32  killed in Mississippi, 33 in Tennessee, 11 in Arkansas, 14 in  Georgia, eight in Virginia and two in Louisiana.
Miranda said the estimated costs would be “in the same  ballpark” as an Oklahoma City tornado outbreak in 1999 that  caused $1.58 billion of damage and a 2003 tornado outbreak in  Kansas, Missouri, Arkansas and Oklahoma that caused $4.5  billion of damage.
“I would not be surprised to see it in the mid-level  billions, singular billions, of dollars,” Miranda said.
The Browns Ferry nuclear power plant in Alabama was  expected to be shut for days, possibly weeks, as workers  repaired damaged transmission lines.
But the backup systems worked as intended to prevent a  partial meltdown like the nuclear disaster in Japan.
“The reactors will remain shut until we have restored the  reliability of the transmission system,” said Ray Golden,  spokesman for the Tennessee Valley Authority, which owns the  3,274-megawatt plant.
Up to 1 million people in Alabama were left without power.
Daimler said it had shut down its Mercedes-Benz vehicle  assembly plant in Tuscaloosa until Monday because of the  tornadoes, but the plant itself sustained only minor damage.
