In the following passage: "The jetliner crash was an accident foretold."
Can I replace "foretold" by "forecast"?
Not really, unless there was something that indicated the probability of a crash.
Foretell applies to the telling of the coming of a future event by any procedure or any source of information "Seers foretold the calamity".
Forecast adds the implication of anticipating eventualities and is usually concerned with probabilities rather than certainties "He forecast heavy rain".
