Mumbai city is marooned in rains.
Is this sentence grammatically correct? I have read some sentence formations in Collins dictionary but couldn't understand how to use it in a sentence. There were many forms:
1) He spent twenty-four hours marooned in the cab of his vehicle. (marooned is here followed by preposition in)
2) I was temporarily marooned at home by my injured knee.(marooned is here followed by preposition at)
