Tropical Storm Kirogi

Tropical Storm Kirogi (13W), located approximately 470 nm east of Misawa, Japan, has tracked northwestward at 19 knots over the past six hours.

TS 13W is approaching 40n and is expected to continue transitioning from a warm core tropical system to a cold core subtropical system. The storm will succumb to increasing vertical wind shear and decreasing sea surface temperatures as it gains latitude and completes subtropical transition during the next 12 hours. Maximum significant wave height is 17 feet.

Tropical Depression Kirogi

A tropical disturbance formed within a large monsoon trough late on August 2, and the JMA mentioned it as a tropical depression northwest of Wake Island early on the next day.

On August 4, the JTWC issued a TCFA on this subtropical system, and later upgraded the system to a tropical depression late on the same day. On August 5, the JTWC upgraded the system to a tropical storm. Early on August 6, the JMA reported that the system had become extratropical. However, the JMA designated it as a tropical storm with the name Kirogi early on August 8.

Tropical Depression Kirogi (13W), located approximately 745 nm east-southeast of Misawa, Japan, has tracked northwestward at 14 knots over the past six hours. Maximum significant wave height is 15 feet.
