without warning
Out of blue
Without warning describes something happening suddenly, with no advance notice or signal.
Events that occur without warning catch people unprepared: The storm struck without warning.
The phrase often accompanies dramatic or dangerous situations—attacks, layoffs, medical emergencies—where prior notice would have allowed preparation or prevention.
