William Typhoon update: its center has been moving southward, currently expected to pass over Sasebo. However, it is more of a tropical storm so will likely result in a welcome breeze and showers.
My go-to website for typhoons is the Joint Typhoon Warning Center, run by the US Navy, which has a vested concern in windy, watery-type phenomenon. https://www.metoc.navy.mil/jtwc/jtwc.html
