Tropical Storm Higos (2008)


Tropical Storm Higos, known in the Philippines as Tropical Storm Pablo, was a tropical storm during the 2008 Pacific typhoon season. The name "Higos" is the Chamorro word for fig.

Meteorological history

At 18:00 UTC on September 28, the Japan Meteorological Agency assessed the formation of a tropical depression near Palau. At 06:00 UTC the next day, the Joint Typhoon Warning Center issued a Tropical Cyclone Formation Alert on the westwardly tracking disturbance, designating it as Tropical Depression 21W. Upon development, the storm showed signs of improving organization. Consolidation continued as the storm approached the Philippines at the eve of October, though intensification was tempered by increasing wind shear and interaction with the archipelago. On September 29, the storm entered the area of responsibility of the Philippine Atmospheric, Geophysical and Astronomical Services Administration, who locally named the system Pablo. The tropical cyclone grazed eastern Samar and tracked towards southern Luzon—with the JMA noting little change in strength—on September 30, guided by a nearby subtropical ridge. As the storm moved across the Philippines, its center of circulation became elongated and difficult to locate, though deep convective activity initiated near the center as the storm began to accelerate into the South China Sea on October 1. The JMA upgraded the cyclone to a minimal tropical storm by October 2 with sustained winds of 40 mph and a minimum pressure of 996 mbar ; Higos would not strengthen further throughout its evolution in the South China Sea. With the upgrade, the system was named Higos. In contrast, the JTWC noted that the system had become disorganized in the same timeframe with a lack of consolidation noted in microwave satellite imagery. Higos remained ill-defined the next day and was consequently downgraded to a tropical depression by the JMA. On October 4, the weakening system crossed eastern Hainan and slowed considerably, with land interaction and wind shear creating hostile environmental conditions for Higos. Higos drifted northeastward into mainland China as a tropical depression and eventually dissipated early on October 6.

China

China issued an orange alert on for Higos and the State Flood Control and Drought Relief Headquarters activated a third degree emergency response on Friday to prevent flooding, while in Hong Kong, the Standby Signal No. 1 was issued at 7.30 p.m. on October 2 when Higos was about 700 km south of Hong Kong. All tropical cyclone warning signals were cancelled at 10.30 p.m. on October 4 as Higos made landfall over western Guangdong and weakened.

Impact

In Hong Kong, a sheet of glass fell off from a shopping centre in Tsim Sha Tsui when the Strong Monsoon Signal was in force. Two vehicles were damaged and a person was slightly injured during the incident. In addition, a scaffolding was reported loose in Kowloon Bay., however its heavy rainfall may have stopped a potential drought from starting.
