Typhoon Wutip Update #7

Issued (22 UTC) 6am PhT 092913

Typhoon Wutip has weakened further this morning as it passes south of Hainan Island. The center of Wutip was last located approximately 330km south southwest of Haikou, Hainan or about 600km southeast of Hanoi, Vietnam. Maximum sustained winds are down to 150kph with gusts of up to 185kh making Wutip a Category 1 Typhoon. It is currently moving westward at 20kph.

Latest satellite image shows that the Central Dense Overcast remains uniform with strong convective activity still forming near the center. Latest microwave image suggest that the eyewall replacement cycle is in its latter stages with a new eyewall nearing completion. We might see an eye try to form later today but the imminent landfall in Vietnam should limit any intensification that could happen.

Southern portions of Hainan Island are seeing light to moderate rains due to the bands from Typhoon Wutip. Coastal areas are also seeing winds of up to 100kph along with high waves. Some areas there in Hainan could see up to 100mm of rain through the next few hours.

Typhoon Wutip will continue moving westward and could make landfall near Vinh, Vietnam later this afternoon. Strong and damaging winds are possible along the landfall areas. Furthermore, Wutip could drop as much as 200mm of rain in the region which could cause flooding and landslides. Wutip will continue moving westward, rapidly weakening along the way, and will cross into Laos by Tuesday morning bringing rains in that part of the region as well.

We'll have another update later today.
