 The noise is said to be "doleful and disagreeable", like the groans and sighs of someone deathly ill, and to sound three times (growing weaker and fainter each time) as a threefold warning before the person expires.Along the Glamorganshire coast, the cyhyraeth is said to be heard before a shipwreck, accompanied by a corpse-light.Like the Irish banshee and the Scottish Cailleach, to which the cyhyraeth and the Gwrach y Rhibyn are closely related, the cyhyraeth also sounds for Welsh natives dying far from home.
