When the word sounds too weak. If the situation involves serious danger, “vulnerable” may not communicate enough urgency. Instead of “The building is vulnerable,” say “The building is defenseless against a major earthquake.” This adds weight to your warning.
When the word sounds too formal. In casual conversation, “vulnerable” can feel stiff. Instead of “I feel vulnerable about my presentation,” say “I feel nervous about my presentation.” This sounds more natural among friends.
