Discussion:

Wutip made landfall on the western Leizhou Peninsula at about 0500 UTC at an estimated 1-minute advisory of 65 kts. Since then, Wutip’s inner structure has deteriorated rapidly as it pushes further inland, although some remnants of the inner core and eye remain and are evident on local radar imagery. The central dense overcast has taken on a sheared appearance, although CIMSS shear data indicates that effective shear over the system is actually quite low. This is more likely due to an approaching frontal trough impinging upon the system. The intensity is lowered to 45 kts, which may actually be conservative since the most recent CIMSS D-PRINT estimate was 53 kts.

Wutip should continue to weaken rapidly as it moves further inland, and it is forecast to turn toward the east-northeast ahead of the approaching front. Wutip is likely to decay into a trough ahead of this front on Sunday, with the remnants being absorbed by a larger extratropical low near Korea on Monday. Some model guidance continues to suggest that the circulation of Wutip could survive a bit longer, but it will most certainly have become post-tropical before reaching water.
