Noon Saturday, Aug. 20, Japan time: A tropical storm formed overnight east of Japan and it appears as if it will remain off the east coast for its projected very short existence. According to the Joint Typhoon Warning Center, 13W has peaked at 46-mph sustained winds and 58-mph gusts and is forecast to pass 275 miles northeast of Yokosuka Naval Base at about 11 p.m. Saturday before curving northeast and dissipating. Kompasu is Japanese for a V-shaped device for describing circular arcs -- what we would have called a "compass" in old school math classes in the 1960s and 1970s.
