[PT-What does this mean for me?]
The simple fact of forecasting hurricane swells is that often the model cannot pick up the true intensity of the wind and swell which is why specialist models run by the NHC are so useful. However, our swell models are forecasting mid-range swells with an extremely high period (in excess of 16 seconds) impacting first on the outlying Caribbean (Windward Islands) all the way up the Eastern Seaboard to Nova Scotia. Bear in mind that hurricanes have been known to switch course without warning so be prepared for change. But if the current forecast holds good expect the first real hurricane swell of the year for Florida and beyond.
