Late on May 23, the JTWC upgraded Sanvu to a category 1 typhoon, for the system became compact and more organized as an eye was forming. After being upgraded to a severe tropical storm by the JMA late on May 24, Sanvu’s eye directly passed over Iō-tō late on May 25.

On May 25, 2012 at 1500 UTC (11 a.m. EDT/U.S.), Typhoon Sanvu had maximum sustained winds near 60 knots (69 mph/111 kph), slightly weaker than it was on May 24. Typhoon-force winds cover a compact area, extending 25 miles (40 km) from the center, while tropical storm-force winds extend as far as 150 miles (241.4 km) from the center, making the storm over 300 miles (~483 km) in diameter.

Sanvu’s center was located near 23.9 North and 140.3 East, only 100 nautical miles (115 miles/185 km) southwest of Iwo To, Japan and moving to the north-northeast at 7 knots (8 mph/13 kph). Sanvu continues to churn up rough seas, and the Joint Typhoon Warning Center reported that wave heights in the region are as high as 31 feet (9.4 meters).
