TY 02W

Chan-Hom has been upgraded from tropical storm to typhoon status.

It is located in the South China Sea approximately 150 nm west-
northwest of Manila, Philippines, after tracking east-northeastward at 10 knots over the past six hours.

Recent animated multispectral imagery shows a well defined circulation with convective banding biased to the east of the center.

Infrared imagery indicates a depression in the clouds over the low level circulation center(LLCC).

An AMSU-B image shows a broken ring of deep convection with convective bands wrapping into the North, East and South of the system.

Animated water vapor imagery shows well formed dual channel outflow to the Northeast and Southwest.

Upper level analysis shows that the system is moving into an area of increased vertical windshear and near an area of upper-level diffluence.

Maximum significant wave height is 18 feet. Sea surface temperatures remain favorable for further development, but the systems proximity to land will quickly impact its ability to sustain itself.
