Translation of tremendo

His name was Leo and he would become a good friend of mine during the next two weeks. He had a lovely girlfriend where he stayed during my visit. Basically, I slept in his place when he was away.
It seemed like a very cute settlement and a great place to stay in for a night or two and I hoped that they would have rooms. However, since I wasn't sure I decided to carry my backpack with me.
I visited the Hurricane watch center's website on a hourly basis hoping it would just go away, bt hurricane Ivan was on a direct path to Havana. It did not stop my vacation plans and I left the office.
