I think hector has serious potential to make it all the way well into the west pac. Some weenie runs even have it making landfall in Asia? Realistically, the only thing I can see weakening it for the next 7 days is dry air. Upper air pattern generally has under 15kts shear through this period. However, there is quite a bit of dry air forecast to be around the system that may intrude from time to time. SSTs are conducive, albeit not for a particularly intense storm, more than enough to survive off of.
