Highways are getting closed already. It was announced yesterday that Rt. 9 is already closed in anticipation of Talim. Rt. 9 is a main highway. It's the main southern cross island route, merging with 11 on the east coast before splitting again in Taitung and going up the valley.

It looks like there will be a lot of road closures in the next 24 hours or so. The article linked below says they are preparing to close 12 routes around the island, and that's before the landslides start!

Although northern Taitung County didn't get hit too terribly hard by the rains last week, Dawu and Taimali got hit quite hard and there was significant flooding and landslides, resulting in the closure of Rt. 11 in that area. They seem to be more prone to flooding because they are on the central mountain range. Any rain hitting the central mountains runs straight into the rivers south of Zhiben, starting with Taimali, whereas north of Zhiben we have the central valley acting as a buffer of sorts.
