Hinnamnor is forecast to continue tracking generally westward over the next 12 hours under the steering influence of the subtropical ridge to the northeast, JTWC said.1

Still in a favorable environment characterized by warm sea surface temperatures, low vertical wind shear and moderate outflow aloft, the typhoon is forecast to reach a potential peak intensity of 250 km/h (155 mph) or higher by 15:00 UTC on August 31.
