Sep 26, 2019 at 15:20 comment added A Lambent Eye While absolutely correct, I'm afraid the semaphore does not solve the presented problem since it is still an optical system as therefore still subject to the initial drawbacks of the weather. It may even hold up worse due to the fact that lighthouses may penetrate light weather conditions due to the luminescence while the semaphore will be entirely invisible in low light and similar conditions. But complements to an otherwise very good answer.
