I think anything that approaches damage to property/trees etc could also pose a risk to life through falling debris and as such warnings should be issued. It may only affect a very small area in reality but if it makes people aware, then as today’s event in Hampstead highlights, people may have been a little more wary when passing under/by trees/scaffolding etc, but as with all these things it’s pot luck if something happens and your either in the right or wrong place sometimes but forearmed is forewarned as the saying goes! I would rather be made aware of any potential weather event which could harm me or my belongings...it’s then up to me what I do with the information, it’s not nanny state ethics or the if we get too many warning we won’t heed them mentality. Everyone can make their own mind up on warnings given, it’s a choice.
