Why Gulf Stream Wave Heights Can Be 5X Higher Than Forecasted

Why Gulf Stream Wave Heights Can Be Much Higher Than Forecasted
___________
EXCERPT:
"When crossing a boundary current like the Gulf Stream mariners must be aware of the wind and sea forecast before departure and while underway.
If wind waves or swell are opposing the set of the current or if arctic air is streaming offshore at right angles to the current a mariner should anticipate a risk for encountering wave heights from 40% to 100% higher than the general forecast values near the north wall of the current and also crossing eddies."

"..there is documentation of waves being up to five (5) times the expected significant wave height values, as driven by higher winds. "
