雨天決行ですか？って英語でなんて言うの？

If there is a bad storm and we booked an important tour/cruise that we want to go on, sometimes we wonder if it will be cancelled or not.

If we are in this situation, we could ask some questions to the tour guide such as:

1) "Are we still going if it rains?"
2) "Is the tour going to be cancelled because of the weather?"

Tourists always worry about bad weather affecting their plans. It's good to know exactly what will happen in the event of bad weather.
A: "Will the cruise still go ahead if it's raining?"
B: "If it rains, it will be postponed until the following day."

"Will" is the question word to use when asking about something that may or may not happen in the future. "Happen" is another way to say go on or carry on.

I hope that this helps :)

Both of these sentences ask someone if you will still be able to go if it ends up raining.

1. The first phrase denotes that you have to call off your plans due to the weather, which is the rain. When referring to "the weather", this is a common way to talk about the rain without actually saying it specifically, especially if there is a forecast for rain or the weather predicted rain for that day. You can use this in a number of situations, like when there's snow or any inclement weather.
   
   2. "Rain or shine" is a common phrase used when an event continues whether there's good or bad weather. Events like outdoor concerts or private parties will often say "rain or shine" in the event description, so you know that it will not be cancelled even when it rains.
