unpredicted
Caught everyone off-guard
Unpredicted describes something that wasn't foreseen or anticipated: The storm arrived unpredicted.
Unlike unpredictable, which suggests something inherently resistant to forecasting, unpredicted simply means no prediction was made—whether because forecasters missed it or no one was looking: an unpredicted side effect of the medication.
