Tropical Storm (TS) 23w (Hagibis) located approximately 115 nm east-southeast of nha trang, Vietnam, has remained quasi-stationary for the pasat 06 hours. For the past 24 hours the system has remained in a weak steering environment under the competing influences of near equatorial ridging to the south over eastern borneo, and sub-tropical ridging to the northeast of Luzon. The dynamic models are now in better agreement, indicating that the primary steering influence is now the near equatorial ridging to the south. This forecast is based on the consensus of the available dynamic aids. Maximum significant wave height at 240000z is 19 feet. Next warnings at 240900z, 241500z, 242100z and 250300z.
