A rapidly deepening major storm low is forecast to move southeastward from just south of Newfoundland Saturday to west-northwest of the Azores over the next 48 hours. Winds are forecast to increase to 50-65 knots with seas building to 13 meters (42 feet) southwest of the center during the next 24 hours and 55-75 knots with seas to 15 meters (50 feet) west of the center within 48 hours.
This will be a dangerous hurricane-force storm as it will be moving through some of the main trans-Atlantic shipping lanes.
It was less than a week ago when another major storm moved through this part of the North Atlantic producing winds to 75 knots and seas to 19 meters (62 feet). See http://oceanweatherservices.com/blog/2018/02/20/north-atlantic-hurricane-force-storm-affecting-main-shipping-lanes/
