yes, they are SYNONYMS.
The dust storm was ominous.
The dust storm was threatening.
Same thing.
There is a difference between them which makes them less than perfect synonyms. "Ominous" means portentous; it comes from the word "omen" which is a sign or token of something to come. Therefore it is actually more like a warning than a threat.
That is the correct spelling of "ominous" (foreboding).

No. Ominous means showing signs that something bad or unpleasant is about to happen. Threatening means hostile and frightening. An analogy is a comparison between two things, especially a very complicated thing being compared to a simpler thing to illustrate how it works.
In this case, it means scary or foreboding.
