Typhoon HAGUPIT/Ruby – the tracks spread
Typhoon HAGUPIT/Ruby – the tracks spread now more and more. The southernmost and fastest track is maintained by Japan’s JMA. US’s JTWC on the other side sees the typhoon slowly going towards northern Luzon. The other agencies spread between the two extremes. Typhoon HAGUPIT/Ruby becomes more and more a showdown between the forecast models. Meanwhile Typhoon HAGUPIT/Ruby has been upgraded to Super Typhoon Category 4.
The only thing that is clear at this moment is the important role of the high pressure areas in continental Asia. These high pressure areas prevent Typhoon HAGUPIT/Ruby moving northwards. If they weaken, the storm will follow the American track, if they rest stable the storm will follow the Japanese track.

This is the reason why now all eyes are on the isobars maps covering eastern Asia.
