Tropical Storm Ma-on Makes Landfall in Southeast China

Tropical Storm Ma-on made landfall in southeast China on Thursday morning. At 5:00 a.m. EDT on Thursday the center of Tropical Storm Ma-on was located at latitude 22.0°N and longitude 109.2°E which put it about 80 miles (130 km) east of Qinzhou. Ma-on was moving toward the west-northwest at 20 m.p.h. (32 km/h). The maximum sustained wind speed was 50 m.p.h. (80 km/h) and there were wind gusts to 65 m.p.h. (105 km/h). The minimum surface pressure was 994 mb.

Tropical Storm Ma-on made landfall on the coast of southeastern China between Dianbai and Zhanjiang on Thursday morning. The center of Ma-on made landfall near Wuchuan. Ma-on was a strong tropical storm at the time of landfall. The maximum sustained wind speed was 65 m.p.h. (105 km/h). The distribution of thunderstorms and heavy rain in Tropical Storm Ma-on was asymmetrical. Many of the thunderstorms with heavy rain were occurring in the southern half of Ma-on’s circulation. The strongest winds were occurring over the South China Sea. Winds to tropical storm force extended out 130 miles (210 km) from the center of Tropical Storm Ma-on.

Tropical Storm Ma-on will move around the southwestern part of a high pressure system over the Western North Pacific during the next 36 hours. The high pressure system will steer Ma-on toward the west-northwest. On its anticipated track Tropical Storm Ma-on will move inland over southeastern China and northern Vietnam. Ma-on will drop locally heavy rain over parts of southeastern China and northern Vietnam. Heavy rain could cause flash floods in some locations.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Tokage was weakening as it sped away from Japan. At 5:00 a.m. EDT on Thursday the center of Tropical Storm Tokage was located at latitude 41.3°N and longitude 153.9°E which put it about 610 miles (985 km) east of Misawa, Japan. Tokage was moving toward the northeast at 25 m.p.h. (40 km/h). The maximum sustained wind speed was 65 m.p.h. (105 km/h) and there were wind gusts to 80 m.p.h. (130 km/h). The minimum surface pressure was 987 mb.

Tropical Storm Ma-on Develops near Northern Luzon

Tropical Storm Ma-on developed near northern Luzon on Sunday night. At 5:00 a.m. EDT on Monday the center of Tropical Storm Ma-on was located at latitude 16.3°N and longitude 123.4°E which put it about 100 miles (160 km) southeast of Tuguegarao, Philippines. Ma-on was moving toward the west at 11 m.p.h. (17 km/h). The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 60 m.p.h. (95 km/h). The minimum surface pressure was 997 mb.

Former Tropical Depression 10W strengthened to Tropical Storm Ma-on just to the east of northern Luzon on Sunday night. The distribution of thunderstorms in Ma-on continued to be asymmetrical. Most of the thunderstorms were in bands in the southern half of Ma-on’s circulation. The bands in the northern half of the circulation consisted primarily of showers and lower clouds. A strong upper level ridge over China was producing strong northerly winds that were blowing toward the top of Tropical Storm Ma-on. Those winds were causing moderate vertical wind shear and the wind shear was causing the asymmetrical distribution of thunderstorms.

Tropical Storm Ma-on will move through an environment favorable for intensification during the next 12 hours. Ma-on will move over water where the Sea Surface Temperatures are 30˚C. The upper level ridge over China will continue to produce northerly winds that will blow toward the top of Ma-on’s circulation. However, Tropical Storm Ma-on could strengthen during the next 12 hours. Ma-on will weaken when the center passes over northern Luzon, but it could strengthen again over the South China Sea later this week.

Tropical Storm Ma-on will move around the southwestern part of a high pressure system over the Western North Pacific Ocean. The high pressure system will steer Ma-on toward the west-northwest during the next 24 hours. On its anticipated track Tropical Storm Ma-on will hit northern Luzon in 12 hours. Ma-on will bring gusty winds and locally heavy rain to northern Luzon. Heavy rain could cause flash floods in some locations.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Tokage formed southeast of Japan. At 5:00 a.m. EDT on Monday the center of Tropical Storm Tokage was located at latitude 25.5°N and longitude 151.6°E which put it about 1010 miles (1635 km) southeast of Tokyo, Japan. Tokage was moving toward the north at 11 m.p.h. (17 km/h). The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 60 m.p.h. (95 km/h). The minimum surface pressure was 998 mb.

Tropical Storm Tokage Develops Over the Central Philippines

A distinct center of circulation developed within a cluster of thunderstorms over the central Philippines on Thursday and the Japan Meteorological Agency designated the system as Tropical Storm Tokage.  At 10:00 p.m. EST on Thursday the center of Tropical Storm Tokage was located at latitude 11.7°N and longitude 122.0°E which put it near the northwestern tip of Panay Island and about 235 miles (380 km) south-southeast of Manila, Philippines.  Tokage was moving toward the west-northwest at 13 m.p.h. (20 km/h).  The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h).  The minimum surface pressure was 1000 mb.

The core of the circulation of Tropical Storm Tokage is still organizing.  An inner band of thunderstorms wraps around the western and southern sides of the center of circulation.  An outer rainband wraps around the northern side of the circulation from the northeastern to the southwestern quadrants.  Thunderstorms near the core of Tokage are generating upper level divergence which is pumping mass away to the west and north of the tropical storm.

Tropical Storm Tokage will be moving through an environment that is favorable for intensification.  Tokage will be moving over water where the Sea Surface Temperature is near 29°C.  An upper level ridge east of Tokage is producing southeasterly winds which are blowing against the tropical storm.  Although those winds are restricting upper level divergence on the southeast side of Tokage, the overall effect of the vertical wind shear is minor.  Tropical Storm Tokage is likely to intensify during the next day or two and it could reach typhoon intensity.

Tokage is moving around the southwestern portion of a subtropical ridge which is steering the tropical storm to the west-northwest.  That general motion is expected to continue for another 12 to 24 hours.   After that time Tropical Storm Tokage will reach the western end of the subtropical ridge and it will begin to move toward the north.  On its anticipated track Tropical Storm Tokage will pass near Mindoro Island and the Calamian Group during the next 12 hours.  It will bring gusty winds and heavy rain to those islands.  Tokage is likely to pass west of Luzon.
