Animated wind chart for 29th Spetember to 3rd October 2019, the track of ex-hurricane Lorenzo as it hits Ireland on 3rd October. Red is storm force winds, black is hurricane-force.
Easy to visualise how any migrants launching themselves SE from Newfoundland could get caught up in the accelerating storm system and end up on the 'wrong' side of the Atlantic.
