What is a gray swan called?

A gray swan refers to an event or phenomenon that is unlikely but possible, and has significant consequences if it occurs. It lies between black swans, which are highly improbable and impactful events, and white swans, which are predictable and expected. The term is often used in risk management and forecasting to describe events that are overlooked but can still happen. Gray swans are typically more anticipated than black swans but less certain than white swans.
