danger signals
Signs of trouble
Danger signals are warnings—whether visible, audible, or sensed through intuition—that alert someone to potential harm or trouble.
The phrase applies equally to literal indicators like flashing lights or alarm sounds and to figurative ones like behavioral red flags in a relationship or worrying trends in financial data.
The stock's volatility was one of several danger signals investors ignored.
When your instincts register danger signals, they're picking up on cues that something is wrong, even if you can't articulate exactly what.
