I'm afraid that driving may be dangerous now that the hurricane is coming close. I would like to have a rain check on the lunch today. I look forward to another chance to have lunch with you.
Excuse me. The hurricane is approaching and thinking about safety, I'm also concerned about driving my car, so I think I'll have to postpone today's lunch. I look forward to an opportunity at a later date.
I am sorry, but the hurricane will be close, so I am afraid that I drive a car safely. So thank you very much for asking me, but I'd rather not go out to today's lunch. I look forward to the next opportunity.
I'm sorry. Hurricane is coming, and as I consider safety I do not feel comfortable driving a car so I'd like to cancel lunch today. I'll be looking forward to the next opportunity.
