英语翻译请问是weather allowed还是allowing,

独立主格结构为：If weather allowing (其实用permitting更为常见),we'll go out for a tour tomorrow (we'll go outing tomorrow; 或：we'll go on a sigh-seeing tour tomorrow) 出去旅游有不同的说法,要看说者的具体意思来具体翻译,提供的3种只供参考.类似的独立结构如：If time permitting,I'll go see you tomorrow.His book having been finished,we'll go out celebrating tomorrow.

we will go on a journey tomorrow with the weather permitting.可以用allowing，allowed不行，因为天气与动词允许是主动的关系，所以用动词-ing形式。
