Weather related conversation [Unit 9]

A: Excuse me. Have you been waiting long for the train?
B: Yes. It should have arrived 45 minutes ago.
A: We are like being late and I'm feeling sweaty!
B: I didn't think it would be this hot. And the forecast for the weekend is rainy.
A: Good. This heat must not last longer than a couple of days.
B: That's a relief.
A: At least we don't live near in the tropical. It must be hotter.
B: Yes. We're lucky. Here's the train.
A: Good luck. I hope the weather will be better.
