There is no reason to name North Atlantic low pressure systems. None. There are several of them active at the minute. One of them -- now called Barra -- happened to hitch a lift from New Brunswick to Ireland via the jet stream. The speed at which it crossed the Atlantic and got to prominence among the other Ls on the pressure chart illustrates why the phenomenon is so different from summer tropical systems that make a leisurely trip across the Atlantic from Senegal and can be observed for a week before they strike land. Anyway, watch out for flying objects in Ireland today, as you would for any high wind event, even ones that never to rise to the level of a trendy HiCo name.
