Songda (Chedeng) continues to weaken as it moves away from Batanes and Taiwan. It has been downgraded from a Super Typhoon but maximum winds are still around 210kph with gusts reaching up to 260kph. Songda is still a powerful category 3 typhoon.
It was last located approximately 200km northeast of Basco, Batanes. Songda is moving north northeastward at 20kph. As of 5am today Signal #2 is still up for Batanes Group of Islands while Signal #1 is in effect for Calayan and Babuyan Group of Islands.
Rainfall reports in northern Luzon indicate 60-100mm of rainfall in Aparrri, Tuguegarao, and Calayan. Basco is reporting 60-70mm of rain over the past 24 hours.
Latest wind reports from eastern seaboard of Taiwan indicate tropical storm conditions of as high as 80kph wind gusts. Here is the latest radar image from Central Weather Bureau depicting heavy rain just offshore of Taiwan.Radar from Okinawa is also beginning to capture the outer rain bands from Songda as seen here from JMA's radar image:
Typhoon Songda is still forecast to pass just to the west of Okinawa, within 100km, tonight as a strong Cat 3 or Cat 2 typhoon. Based on this IR imagery, you can see Songda starting to encounter strong wind shear. It should leave the Philippine Area of Responsibility today. It will continue tracking northward brushing the southern coast of Honshu on Sunday. Please NOTE that JMA and JTWC are still expecting this to stay off of Japan despite the computer models tracking north.
