A tornado is coming today according to the weather forecast, but it has not been here yet.

Now, I am outside and getting worried that the train company will either delay their service or be out of service because of the terrible storms. I think the Japanese trian system is very weak, because when it is affected by the bad weather, they have to cancle their service at all depots, which has caused a major inconvience for everyone involved(all the passengers).
