    Ry'Lee Meek in Moore, Oklahoma

    says: I was at work when the tornado struck. My dad had to call me and told me to get home right away. I had to go get my brother - who is 14 - from school in the evening. They shut down the whole city and it took three hours to pick him up. The city is pretty much destroyed. One of my friend's mothers was killed. My cousin is a school teacher at one of the elementary schools that got destroyed and she made it out.

    tells the BBC: I got the kids out of the house and got away as fast as I could. We headed for my cousin's cellar but the hail and the rain was so bad that we couldn't get there, so we drove away from the storm as far as we could. After it had calmed down we returned to Moore to see what we could do to help, and to see if everyone was OK. My house is still standing but others in the neighbourhood were not so lucky - some are gone.

We tried to follow the news coverage to see whether their homes were damaged which was quite a disheartening experience. I've never seen anything like this. It's almost unfathomable how much destruction could occur in such a short amount of time.

    reports from Moore: There's lightning in the sky above Moore, flickering on and off every 10 or 20 seconds; at ground level, the only light is from the blue and red flashing lights of emergency vehicles and the bright portable lights with generators at their bases. It is deceptively calm; insects chirrup in the background. Everywhere is covered in a light spray of soggy debris and a film of mud. At the deserted Moore police station cars are spattered with mud.

    1112: Jonny Dymond BBC News, Moore

    Larger concrete structures are still standing - a cinema, a supermarket, reminders of what there was before the tornado struck. But houses, offices and shops have been torn apart by the force of the winds that ripped through here, sturdy telephone poles snapped at their bases, street signs sent flying. And most disconcerting - though unsurprising - is the complete absence of any residents.

    Jerry in Edmond, Oklahoma

    emails: We live in Edmond, about 30 miles north of this. I was working near the airport, about four miles from where the tornado crossed the river and into Moore. In about 10 minutes the skies just erupted. I called my wife and told her to pick up the children at school. The next thing I know I'm getting pounded by golf ball-sized hail against my truck and then the sirens started for the tornado warning. It was terrifying.

     
  53.  
    Jerry Edmond, Oklahoma

    continues: It was due south of me. The hail subsided and as I got out of my truck and looked towards the south, it was total darkness. I heard what I thought was a constant rumbling of thunder towards the tornado. It was the sound of the tornado. A giant WHHHRRRRR and gnashing of metal, debris, and concrete as it ripped across the town of Moore. I'll never forget that sound. Needless to say I made it home and held onto my children and wife. A terrible day.

    says: Tornados are too small scale for current climate models to simulate, so it is not possible to say very much about how strength and occurrence might alter under climate change. But climate change means warmer temperatures and more moisture and that is providing more energy for the types of storms that produce tornadoes in a warmer climate.
