Typhoon CHOI-WAN is moving west in Mariana Islands keeping its very strong intensity. The image below shows that the size of the eye is larger today than yesterday, and the eyewall clouds changed from vertical clouds to sloped clouds. It seems that this change indicates the change of the status from a very tight shape to a little loose shape, but detailed wind information shows that the radius of storm wind suddenly shrunk this morning from 140NM (=260km) to 90NM (=170km). In any case, the typhoon seems to be transformed to a developing stage to a mature stage.
