Oklahoma Tornado: EF5 Twister 'Widest Ever'

The US National Weather Service says the deadly tornado that struck near Oklahoma City last Friday was the widest twister ever recorded.

The 2.6-mile-wide (4km) tornado, which hit the town of El Reno, has also been upgraded to an EF5 category - the top of the scale - and had winds reaching 295mph.

The twister's extreme breadth made it difficult for people to even recognise it as a tornado, said Rick Smith, the Weather Service's chief warning coordination meteorologist in Norman, Oklahoma.

Meteorologists had initially classified it as an EF3, but changed its ranking on Tuesday after surveying the widespread damage.
