Closed Umbrella emoji is just the same item that is illustrated by the ordinary ☂️ Umbrella emoji with the only difference — this one is not open. Yet, it is still used mostly in the context of 🌧 Weather and rain in particular in its direct meaning. This means that it may serve as an illustration for the rainy days in posts, as a reminder to take an umbrella when going out in the messages to someone, a symbol of the ending of the rain, and so on. Also, in its indirect meaning, it sometimes symbolizes the ending of streak of bad luck in the user’s life. (Source: Emojis.wiki, Fair use)
