Super Typhoon Champi Passes Guam, but Travel Warnings Continue

October 18, 2026 | Weather News | Flight Travel News

Super Typhoon Champi passed south of Guam early on Sunday, October 18, bringing damaging winds, heavy rain and dangerous coastal conditions. Although the storm has moved away from its closest point to the island, officials continue to warn residents and travelers that conditions remain hazardous.

Travelers planning to fly to or from Guam and the nearby Northern Mariana Islands should check directly with their airlines and airports for the latest flight information before leaving for the airport.

Champi Makes Its Closest Approach to Guam

According to the Government of Guam, Super Typhoon Champi made its closest approach to Guam at approximately 4:26 a.m. local time on October 18, passing about 10 miles south of Merizo.

Damaging winds and heavy rain continued after the storm's closest approach. Authorities warned of possible flash flooding in low-lying areas, on roads and in places with poor drainage. Dangerous surf and coastal flooding also remained concerns.

The U.S. National Weather Service in Tiyan reported that Champi was moving west-northwest, away from Guam and the Northern Mariana Islands. However, tropical-storm-force winds and hazardous sea conditions could continue even as the storm moves farther away.

What Does This Mean for Air Travelers?

Severe weather can affect airport operations, flight schedules and connections. However, the impact on individual flights depends on local conditions and airline decisions.

• Check your flight status: Look for updates from your airline before travelling to the airport.
• Allow extra time: Weather-related delays and changes may affect airport journeys and onward connections.
• Contact your airline: If your flight is cancelled or significantly changed, ask about rebooking options and applicable passenger policies.
• Check your onward journey: Travelers connecting through Guam or nearby islands should confirm every flight on their itinerary.
• Follow local instructions: Do not travel through flooded roads or approach dangerous coastal areas.

Important: This report does not confirm that every flight has been cancelled or that the airport is closed. Travelers should rely on current airline and airport notices for their specific journey.

Weather Warnings Remain in Place

In its October 18 updates, the National Weather Service continued to report a typhoon warning for Guam and Rota. Conditions and warning levels for Tinian and Saipan were also being updated as Champi moved away.

Warnings can change quickly during a tropical cyclone. Travelers should consult the latest official advisories rather than rely on an earlier forecast or social media post.

What Travelers Should Remember

Super Typhoon Champi's closest approach to Guam had passed by the morning of October 18, but that did not mean all travel risks had ended. Strong winds, flooding, rough seas and changing weather warnings could still affect local journeys.
