That Taiwan CWB site has been light years ahead of the US sites for years. It's embarrassing. Take a look at the state of the US hurricane site: https://www.nhc.noaa.gov/. It's a mess. Yes, you can eventually find everything, after a lot of random clicks. It's just a joke and it hasn't been updated in years if not decades.

I haven't checked out the updated CWB Chinese site in quite a while. It looks snazzy indeed.
