    Chaba continues to strengthen

    9/30/2016 9:05:15 AM

    As of Friday morning, EDT, the center of Tropical Storm Chaba is located about 1,110 miles southeast of Naha, Okinawa, Japan. Chaba is tracking toward the west at 12 mph with highest sustained winds of about 60 mph.

    Chaba is currently being steered by a subtropical high pressure aloft to the west and is encountering very low wind shear, which will continue to aid in further development of the system over the next couple of days. Chaba is expected to begin to veer to the northwest later today as the subtropical high begins to weaken. Chaba will remain over very warm water with relatively low vertical wind shear, allowing the system to continue to strengthen to a typhoon. An upper-level low that currently developed over the Tibetan Plateau will push eastward into eastern China by Sunday. This will increase wind shear aloft over Chaba but actually aid in ventilation of the storm, allowing it to intensify further. Chaba is expected to make a northerly turn by early next week and make landfall as a strong typhoon in Shikoku and southern Honshu by Tuesday next week.
