English: It’s raining.
French: Il pleut.
Your pilots might announce that it's raining at your destination.
“Il pleut” is the generic way to say that it’s raining, and is the way that most French courses will teach students how to say “it”s raining”. “Il” is usually the pronoun “He”, but in this context (and many other contexts in French), it’s known instead as an impersonal pronoun, translating better as “it”, as in “it is raining”.
“Pleut” is the conjugated form of the verb “pleuvoir” “to rain”.
“Il pleut” is technically correct, but is a little bit “textbooky”. As a learner though, it’s perfectly fine for you to use this.
To announce future arrival weather, you can say "il va pleuvoir" "it's going to rain".
In reality, you’ll hear many of your colleagues (and French weather forecasters) use the noun “rain” “pluie” (f).
Our Canadian French for Flight Attendants audio course also opts for “pluie” as we can use it easily without having to form full sentences, nor do we have to worry about conjugating it in the present tense and in the future tense.
