Typhoon Champi: Why Taiwan grounded 977 flights before its closest pass

Taiwan cancelled 977 flights and disrupted ferry services as Typhoon Champi approached, even though forecasts put the storm’s centre offshore. The scale of the shutdown reflects a practical point for travellers: transport operators respond to the storm’s full wind and rain field, and to the conditions along routes and at airports, rather than waiting for the eye to cross land.

Why an offshore track can still bring island-wide disruption

Taiwan’s Central Weather Administration (CWA) said in a bulletin on Friday morning that Champi was about 320 kilometres east-northeast of Eluanbi, the island’s southern tip. It reported maximum sustained winds near the centre of 155 kilometres per hour, gusts of up to 191 kph, and a seven-level wind radius of about 320 kilometres. The CWA warned that the storm’s circulation was already affecting parts of Taiwan and nearby islands.

A forecast track describes the expected route of the centre, not the outer edge of dangerous weather. Rain bands can reach the island well before the centre’s closest approach; mountainous terrain can intensify rainfall impacts, while winds and rough seas can make aviation and ferry operations unsafe. The CWA’s track can also change as new observations arrive.

What the cancellation figures show

CNA, Taiwan’s Central News Agency, reported that the Civil Aeronautics Administration counted 977 cancelled flights from Thursday through 10 a.m. Friday local time: 262 domestic flights and 715 international and cross-strait services. The report said Taoyuan International Airport had cancelled 596 flights between midnight and 9 a.m. Friday. The Maritime and Port Bureau reported 96 affected ferry departures across 10 routes, with nine routes fully suspended and one partly suspended.

Those figures are a snapshot, not a final total. Airlines and transport agencies may add cancellations or restart services as conditions change. A cancelled flight does not mean the aircraft was in the storm’s path; it can reflect safety limits at the departure or arrival airport, along the route, or the need to keep crews and aircraft out of hazardous conditions.

Why the shutdown can outlast the closest approach

Air travel and ferry operations depend on safe conditions across an entire network. Even after the strongest winds move away from one area, airlines may need time to reposition aircraft, crews and passengers. Ports and local authorities also need to inspect conditions before resuming services. Taiwan’s transport agency has asked carriers to publish updates and notify passengers directly.

The approach also prompted local closures and warnings. Taipei’s disaster response centre relayed the CWA alert and advised residents to follow official instructions. Tainan’s government issued local transport measures under its typhoon plan. The impact is not identical across the island, so a city reopening or one route resuming does not mean all services are back to normal.

What travellers should check next

Passengers should check their airline’s live flight status and rebooking or refund instructions before setting out, then confirm airport and local transport notices. Ferry passengers should check the relevant operator and port authority. Residents should follow CWA forecasts and local-government alerts, especially for coastal areas and places exposed to heavy rain.

The key unresolved issue is how long hazardous weather will affect each region and when operators can safely restore normal schedules. The cancellations show how a broad hazard field can disrupt a densely connected transport system even when a storm’s centre is forecast to stay offshore. They do not, by themselves, establish that Champi made landfall.
