Track of TD 15W

Tropical Depression Talas (15W), located approximately 200 nm northeast of Iwakuni, Japan, has tracked just east of northward at 13 knots over the past six hours. Maximum significant wave height is 12 feet.

Animated infrated satellite imagery indicates central convection has significantly eroded and displaced northeast-ward as the system became exposed to very strong (40-60 kt) vertical wind shear associated with a mid-latitude trough digging in from the northwest. The low level circulation center has become distorted and difficult to pinpoint.

Talas is now embedded in the baroclinic zone in the colder waters of the sea of Japan. It is expected to become extra-tropical by TAU 12. The system is also expected to weaken significantly in view of the harsh environmental conditions, however it will be closely monitored for signs of regeneration.
