Hope they didn't put too much faith in the height of the base of the lowest cloud. At 0400 hrs in the morning and in the dark cannot have been too accurate. Everyone knows the world doesn't stand still as regards most things, just look at the poor old dinosaurs. Everything is changing all the time. As you say what they come out with is a load of codswallop. Suppose they have to do something in life maybe a well paying job putting the general public in panic mode. Someone somewhere along the food chain is making money from it. Cheers J>
