"The storm is picking up."
Translation:La tempête se lève.
Was that not accepted? I also thought them fairly synonymous.
Perhaps it is because "une tempête " is generally characterised by very strong wind, while "un orage " is characterised by thunder and lightning (between clouds or between clouds and the ground). (Ref: WordRef).
With that description in mind, as "se lever", in meteorological terms, is used to describe wind, I could only assume that this is the reason it is referring to une tempête.
Perhaps a native speaker could clarify this for us.
Probably because it isn't a close literal translation. Duolingo likes to teach vocabulary in both directions and "la tempête se lever" back translates to "the storm is picking up" so if the sentence can be literally translated, go with that.
That means "The storm is nearly here" and indicates it hasn't yet arrived whereas "The storm is picking up" indicates that it has arrived and is intensifying.
"se leve" means "to rise", "to get up" and, in the sense of the wind, "to pick up".
"La tempête se lève" → "The storm is picking up"
Very frustrating! I'm trying to test out but I keep getting dinged for translations that are correct but not to DL's taste. With this one, I said, "la tempête grandit", which seems to be correct, but I was marked wrong.
