Lupit (22W) has been downgraded from a typhoon to a tropical storm. Now located approximately 200 nm east of Okinawa, Japan, the system has tracked northeastward at 18 knots over the past six hours.

Animated infrared imagery indicates 22W is starting to elongate to the northwest and that the deep convection has weakened and shifted to the northeast of the low level circulation center.

Additionally, Lupit is showing the signs of moderate to high vertical wind shear and PGTW has started to use the extratropical fix method, yielding a value of 45 knots.

Lupit has started to interact with the baroclinic zone, will continue to accelerate into the mid-latitudes, and will complete extratropical transition southeast of Tokyo, Japan, by TAU 24. Maximum significant wave height is 22 feet.
