Port certainly closed today. I would assume it will be closed tomorrow based on last wind/wave forecast I saw (18kt from South mid day tomorrow). but never say never if the forecast changes. I would imagine it will be open Monday. Obviously keep an eye on the disturbance behind this one for diving Wednesday/Thursday
I would generally defer to others about visibility and currents, but will give my thoughts anyway. . I am sure the visibility will be down tomorrow (Irrelevant if port is closed ) and probably into Monday if for no other reason than the rain. My assumption would be visibility will be mostly better by Tuesday/Wednesday, but that is only a slightly educated guess.
I have seen some wicked currents after storms in the area but that may depend on exact track and size of the storm. Currents a disaster after some storms, but had some storms pass nearby and didn’t notice much of a current change. Given the fact that we have normal large scale south to north current patterns , most disruptions and visibility issues don’t last long before things go back to normal. Once again , that is my two cents but if Dave/Christi etc say otherwise I will will defer to them. I certainly wouldn’t change any travel plans based on Gamma (other than if I were flying today ). Looks like United has pushed today’s flights until tomorrow
