What does 'imminent' refer to in terms of turbulence warning?

The term 'imminent' in the context of turbulence warning refers to conditions that are expected to occur very soon, often without much or any advance notice. This means that the turbulence could happen suddenly and unexpectedly, allowing little time for the crew and passengers to prepare for it. In aviation, recognizing imminent hazards is critical for safety, as it emphasizes the need for immediate attention and action to ensure the well-being of everyone on board. In contrast, other options imply varying degrees of notice or preparation, which do not align with the definition of 'imminent'.
