Considering the strength of the storm, the OPC 96-hour forecast was exceptionally accurate. The GFS and European models were forecasting winds greater than 80 knots (90 mph) and wave heights over 55 feet. The ASCAT passes largely missed the strongest winds (highest observed were 60 knots (70 mph), but there were reports of waves near the Portugal coast between 90 and 100 feet, nearshore! On the RGB Air Mass imagery animation, you can see the red and orange shaded colors drawn into the center of the cyclone. This area represents warm, dry…
