Following peak intensity , Chan @-@ hom began to intake dry air beginning on May 25 . At roughly the same time , the typhoon began to weaken and accelerate towards the northeast . Conditions continued to worsen as the storm moved further north , and as the cyclone passed east of Minamitorishima , it was downgraded to tropical storm classification . By this time , Chan @-@ hom had lost much of its convection due to wind shear . Early on May 27 , Chan @-@ hom had fully transitioned into an extratropical cyclone , and these remnants continued to track towards the northeast . These extratropical remnants dissipated south of the Aleutian Islands the following day . Early in the typhoon 's existence , Chan @-@ hom posed a potential threat to Guam , but remained well east of the island . However , after passing to the northeast , winds from the typhoon fanned volcanic ash from the recently erupting Anatahan volcano towards the island , prompting precautionary measures in Guam . Ashfalls were reported on the island , forcing the cancellation of several flights . As a tropical storm , Chan @-@ hom caused some damage to homes and crops on Chuuk , mostly due to heavy rains brought forth by the storm . Offshore , a 1 @,@ 040 ton fishing vessel , the Nien Feioch , sank during the storm . The ship was valued at $ 16 million .
