Sitting here, on here, I notice a hissing, which gets louder and more urgent, so I get up and go and see what it is and the noise leads to my upended bike where the back tyre is rapidly deflating through the valve. Strange, I have never had that before, a duff valve then, but why now, a change in atmospheric pressure ?
