Tropical Cyclone 10W (Ma-on) – Final Warning

According to the JTWC Warning number 16, sustained winds were 45 knots with gusts to near 55 knots.

Radar data confirms that ts 10W made landfall just southwest of Yangjiang, China, and has since rapidly moved inland. Animated multi-spectral satellite imagery depicts a sheared system, with the bulk of the deep convection sheared to the southwest of the increasingly diffuse low level circulation center.

The system is forecast to continue moving a rapid clip to the west-northwest along the southern periphery of a deep subtropical ridge to the north, skirting just north of the Gulf of Tonkin shoreline, crossing far northern Vietnam and ultimately dissipating as a significant cyclone over far southwestern China no later than 24 hours.

While not likely at this time, there remains a small chance the system could duck down and touch its feet into the Gulf of Tonkin. If this occurs however, it will be short lived and unlikely to lead to any re-intensification of the system.

Tropical Cyclone 11W (Tokage) – Final Warning

According to the JTWC Warning number 14, sustained winds were 45 knots with gusts to near 55 knots.

Animated enhanced infrared satellite imagery depicts a rapidly dissipating system, with a fully exposed low level circulation center, rapidly transiting northeast along the northwest periphery of a deep subtropical ridge to the southeast.

The system is rapidly transitioning to a fully extratropical cyclone as it starts to come in-phase with an upper-level trough, and develops enhanced low level temperature advection. The system will complete extratropical transition within the next 12 hours, as a gale-force low.
