Super typhoon Champi packs 240 km/h winds: 5 facts about the powerful Pacific storm

Super Typhoon Champi has become one of the most powerful tropical cyclones of 2026, with peak sustained winds reaching 185 miles per hour over the western Pacific.

Although Champi has started to weaken, forecasters are watching its path toward Japan and the wider effects it could have on weather patterns. Here are five key facts about Super Typhoon Champi and what could happen next, as per WBALTV, Fox News and The Weather Network.

Super Typhoon Champi

The storm strengthened rapidly near Guam before moving toward the Philippines and waters closer to Taiwan. Champi reached peak sustained winds of 296 km/h on October 20, making it the strongest tropical cyclone of 2026 by wind speed at that point. Its intensity was equivalent to a Category 5 hurricane.

The storm also recorded a central pressure of around 895 millibars. Hurricane Polo, which previously held the year's wind-speed record, reached 285 km/h winds and a lower central pressure of 892 millibars. That lower pressure means Polo was more intense by that measure, even though Champi recorded stronger winds.

Champi has also been described as tying Super Typhoon Sinlaku for the strongest storm of the year, based on maximum sustained winds.

5 facts about Super Typhoon Champi

1. It passed close to Guam.

Champi passed about 16 kilometres (10 miles) south of Guam's southern tip on October 18. The storm knocked out power in parts of the island and temporarily disrupted local weather radar operations.

2. Its winds strengthened rapidly.

Champi's maximum sustained winds climbed from 70 mph to 140 mph in about 24 hours. Warm ocean water, deep moisture and low wind shear helped the storm strengthen so quickly.

3. It is threatening areas near the Philippines.

As Champi moved across the western Pacific, the Philippines faced concerns about heavy rain and dangerous seas. PAGASA maintained Tropical Cyclone Wind Signal No. 2 over Batanes and warned that waves could reach 10 metres (33 feet).

4. It is expected to weaken as it moves north.

Forecasters expect Champi to turn northwest and eventually recurve toward Japan. However, the storm is forecast to encounter less favourable conditions, potentially weakening to Category 4 or Category 3 intensity by Thursday and Friday.

5. It could influence weather far beyond the Pacific.



Champi is interacting with the jet stream, which may affect weather patterns in other parts of the world. Forecasts point to possible downstream effects on Canada's weather toward the end of October and into early November.

What happens next as Champi moves toward Japan?

Champi's future strength will depend on the conditions surrounding it as it moves away from the warmest waters. Although ocean temperatures near 30°C have supported its rapid intensification, less favourable conditions are expected along its projected path.
