Christ on a bike, I thought we'd cleared this one up a fortnight ago.
We only take the warnings off the ATIS when the period of validity runs out. Warnings are issued by the Met Office and unless they send out a message to cancel the warning, we leave it on until it is no longer valid.
Now for goodness sake, leave us to do our job and get on with flying your tin tubes! You don't see me criticising the way you fly, the fact that you seem unable to put the plane down on the TDZ makings rather than halfway along the runway, or when you block our frequency cos you haven't had the wit to press the right button before launching into your tiresome "Hi my name's Nigel Personality-Bypass and I'm your captain for today..." spiel.
We put the warnings out for your benefit. Get over it and move on!
