Wonder what their policy is for 'closing the gate'. The gates were installed after the the preventable tragedy of the tour buses going over the edge two years ago, but it seems they haven't fixed on a clear policy of when to close them. As i was driving through it, the roads were already becoming rivers in some sections and rocks were littering the road - you could see if it kept going at that level then something was going to seriously give. You know that coz the drive is full of stark reminders of where it has given before. Perhaps a 'gate-closing' trigger worked out on the rainfall level per hour would be a good idea regardless of whether it is a direct hit from a typhoon or not. At the moment they seem to close them when they get word that they have become impassable.

Didn't notice anything in the news article where CWB explained how they managed to miss warning everyone of a potentially deadly downpour in Ilan.
