Typhoon Sanba to Strike Okinawa and South Korea
Super Typhoon Sanba (Karen) is located about 300 nautical miles south-southeast of Kadena Airbase, Okinawa, Japan. The storm's intensity has waned slightly, with wind speeds dropping from 150 knots (Category 5) to 135 knots (Category 4) since yesterday.
The current forecast indicates that wind shear is expected to continue to increase as the storm moves north into higher latitudes, consequently beginning a weakening trend for the storm. Sanba is predicted to be a Category 3 when approaching Okinawa and a Category 2 storm when it strikes South Korea on Sunday, September 16. The wind losses are expected to be low, however, Sanba poses a significant flood risk in South Korea.
Sanba is the 16th named storm and 3rd super typhoon of the 2012 Pacific Typhoon Season. It is the 3rd storm expected to make landfall in South Korea, following Khanun (Enteng) and Tembin (Igme) this season.
