Tropical Storm Usagi Develops: Potential Impact on Taiwan and Philippines Reassessed

Tropical Storm Usagi has formed in the Western Pacific, with the potential to impact Taiwan while already affecting the Philippines. The storm is moving west-northwest with maximum winds of 72 kph. As predictions indicate a possible northward turn, Taiwan remains cautious, having issued heavy rain advisories, amidst a rare occurrence of four simultaneous tropical systems in November.

Tropical Storm Usagi has emerged as the fourth tropical storm in the Western Pacific within just ten days, currently posing potential threats to Taiwan while already placing the Philippines on alert. As reported by Taiwan’s Central Weather Administration (CWA) on November 12, Usagi is situated approximately 660 kilometers northwest of the Yap Islands, with maximum sustained winds measuring 72 kilometers per hour and gusts reaching as high as 101 kilometers per hour. The storm is tracking west-northwest at a speed of 27 kilometers per hour and is expected to be located 760 kilometers east of Manila by the morning of November 13. Predictive models indicate that Usagi’s trajectory has shifted northward, which may result in the issuance of sea warnings in the vicinity of Taiwan. Despite initial uncertainty, forecaster Chen Pei-an from the CWA stated that the storm may turn northward, potentially impacting waters east of Taiwan over the weekend. The Philippines, taking precautionary measures, has issued an advisory through its Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) urging readiness for the approaching storm, locally referred to as “Ofel.” Usagi promises to intensify in the coming days and could escalate into a typhoon by November 13. This occurrence marks a historic event, as it is the first time four tropical storms have been recorded simultaneously in November, with the other systems being Tropical Storms Yinxing, Toraji, and Man-yi. Notably, previous storms have had minimal impact on Taiwan, and conditions suggest a rapid depletion of these systems shortly, especially as Yinxing is forecasted to weaken soon. In anticipation of Usagi’s developing weather patterns, the CWA has also issued a heavy rain advisory for several northern areas of Taiwan, including New Taipei and Keelung.

The context surrounding Tropical Storm Usagi involves the increased frequency of tropical storm formations in the Western Pacific region, particularly concerning how these systems can impact coastal nations like Taiwan and the Philippines. Traditionally, the formation and trajectory of these storms are closely monitored by meteorological agencies to preemptively manage potential effects on local populations. Historically, simultaneous occurrences of multiple storms have raised concerns about possible severe weather affecting several countries at once, highlighting the unpredictability of tropical weather patterns in this region. The recent development of Usagi is particularly significant as it follows closely on the heels of three other storms, suggesting unusual meteorological activity this season.

In summary, Tropical Storm Usagi represents a developing weather concern for both Taiwan and the Philippines, with the potential for significant impact on local conditions. As the storm progresses, both nations remain vigilant in monitoring its path and intensity. The historical context of such an occurrence marks a notable event in cyclone activity for the region, necessitating careful forecasting and preparedness efforts by relevant authorities.
