TAIPEI (TVBS News) — Taiwan's Central Weather Administration (CWA, 中央氣象署), the island's national meteorological service, confirmed that Typhoon Krosa (柯羅莎) poses no direct threat to Taiwan despite its formation from a tropical depression northwest of Guam. The CWA announced Krosa's development Thursday (July 24), with prominent meteorologist Wu Der-romg (吳德榮) emphasizing the storm's northern trajectory ensures Taiwan remains safely outside its impact zone. The typhoon's path will keep it well away from the island's populated areas and critical infrastructure.
Wu highlighted the Fujiwhara effect occurring between Tropical Storms Francisco and Co-May, a meteorological phenomenon that will bring sustained rainfall to northern and central Taiwan through July 27. The meteorologist referenced European Centre for Medium-Range Weather Forecasts data showing Typhoon Krosa strengthening north of Guam while remaining isolated from other weather systems. This separation prevents the typhoon from engaging in the characteristic meteorological "dance" with nearby storms, ensuring Taiwan's continued protection from direct impact.
The Central Weather Administration's detailed forecast map shows Typhoon Fengshen, with its loose structure, moving north from west of the Ryukyu Islands. Typhoon Jangmi advances northeast while weakening as it passes over Luzon. Wu emphasized that through July 27, the outer circulation of Francisco and Co-May, combined with monsoon currents, will bring substantial rainfall and strong gusts to northern and central Taiwan. Southern regions will experience localized showers and potential thunderstorms during this period.
Wu's extended forecast predicts that central and southern Taiwan will experience persistent rainfall from July 28 to 31, with meteorological conditions favoring the development of isolated severe weather events. The eastern coastal regions will encounter significantly lighter precipitation patterns, experiencing only brief, intermittent showers during this four-day period. This weather pattern reflects the complex interaction of multiple tropical systems and seasonal atmospheric conditions affecting different parts of the island with varying intensity and duration. ◼
