Karding maintained its intensity as a tropical depression due to moderate to strong easterly shear, despite persistent convection surrounding the system.

[3] By August 8, a METOP-A ASCAT image showed that the system had winds of 35 knots, hence the JTWC upgrading it to a tropical storm.

Though by 12:00 UTC of August 11, the JMA considered that Yagi reached its peak strength with 10-minute winds of 75 km/h (45 mph) and a minimum pressure of 990 hPa.

[6] By 21:00 UTC of that day, the JTWC issued their final advisory on Yagi,[7] but continued to track it until it weakened further into a tropical depression early on August 13.

Although Yagi (Karding) didn't make landfall in the Philippines, the storm enhanced the southwest monsoon which brought extreme flooding towards many regions within the country.
