U.S. Storm Signal Nylon Flags 36"

Our U.S. Storm Signal flags are an essential product for any dock, boat club or marina. Each set comes with two 36"x72" small boat advisory pennants and two 36"x36" weather warning flags. These storm signal flags are made of a heavy weight marine-grade nylon and finished with a canvas header and solid brass grommets that won't corrode. The weather warning flags feature a fully sewn black square for longer durability. Storm signal flags are designed to be used as a set of four to indicate current weather conditions as well as oncoming stages of a storm on the horizon.
