"Show me just what Mohammed brought that was new, and there you will find things only evil and inhuman, such as his command to spread by the sword the faith he preached." -Manuel II Paleologus
It doesn't have to be. With winds that strong, at that altitude, it will feel like it. I pray for their safety, but it's not looking good. With this new storm moving in, it will probably be Sat at the earliest that they can start searching for them again. I'm sure they didn't have enough supplies with them to last over a week. It was only supposed to be a 2 day climb. Even if they planned that something could go wrong, I doubt they planned for something lasting this long.
I pray they are safe, but time is not on their side. And neither is the weather.
