Usage Note
Imprévisible is built from the prefix im- (negation) + prévisible (foreseeable), itself from prévoir (to foresee). It applies equally to people and events (un homme imprévisible, une situation imprévisible) and is stronger than incertain (uncertain), implying a complete inability to forecast.
Examples
"La météo est souvent imprévisible en montagne."
Natural Translation
The weather is often unpredictable in the mountains.
