This has the potential to bring a lot of rain to Taidong/Hualien/Ilan (actually all the way to Japan) as tracks have it sliding right up the coast. With that trajectory, it will keep feeding rain in over an extended period of time as the rain drifts up from the south from the approaching typhoon, meaning an accumulation effect that will begin days before the typhoon even arrives. Remains to be seen whether it stays off-shore or makes landfall - obviously the closer to the coast, the worse the impact. JTWC has max wind gusts reaching 125kts, which is not massive, but big enough - though it's the rain that will do the damage.
