need help on italicized portion of the sentence?

1.The weather remaining turbulent, we will postpone our canoe trip.

remaining or turbulent

if the remaining turbulent,will be postpone our canoe trip and i think its prepositional phrase with a gerund?

Please do yourself a favor and read over what you posted. It makes no sense.

Use proper capitals, etc.

am i right?

okay and the question is asking what is the grammar function of the italicized words or phrase

so did i get it right??

Which words are italicized?

I'd start the sentence with "If" -- how will you rephrase if you start with that word, too?

1.The weather remaining turbulent, we will postpone our canoe trip. <~~That's your original sentence, right? And you don't have to rephrase it?

There is no preposition (and therefore no prepositional phrase) in that sentence.

so that's not the grammatical structure of it? but doesn't it have a gerund in it?
