Can someone explain to my why met office warning sometimes mention a county but when you look at the weather for actual towns it doesn't show the warning. Today for instance Blaenau Gwent is under the red warning but when I look at the weather for Tredegar, ebbw vale, Brynmawr, abertillery etc (basically every town in Blaenau Gwent) it still shows Amber. I've noticed this previously with warnings.
