Perhaps be more prudent if leaving your boat afloat by doubling up lines and preventing chafe. If ashore, remove the extra windage. My insurance allows my mast to remain up but not with sails or cockpit cover up. Excessive rain with wind may mean fresh water getting in through hatches in the vent position. It could be a damp start to winter prohibiting any opportunity for early winter paint, varnish work. It could be a more mouldy conditions as well, so get the sails dried away from the boat and remove anything likely to hold damp, if possible.For the west coast of Scotland, it typically increases the likelihood of a milder, wetter, and windier start to winter driven by an amplified Atlantic jet stream, potentially followed by a colder, calmer late winter.
Direct Weather Influences
Increased Rainfall: Strong low-pressure systems from the Atlantic hit western high spots and hills, creating heavier and more frequent rain and higher localized flood risks.
Milder and Stormier Autumn/Early Winter: Southerly and westerly winds push warm, moist air across the coast, meaning fewer crisp, freezing days and more gray, damp weather.
Potential Late-Winter Cold Snaps: Historical patterns show strong El Niño events can transition into colder, calmer spells in late winter as atmospheric blocking patterns set in.
A couple of years ago we had some strong winds in the marina and a lot. of boats were moving significantly on slack lines with some breaking. There was a lot of fenders jumping out and stuff blowing
