Super Typhoon Champi has exploded into one of the most powerful storms seen anywhere on Earth this year — reaching wind speeds of nearly 185 mph and briefly taking the top spot as the strongest tropical cyclone of 2026 by wind speed.
Passing near Guam
The massive storm, churning across the western Pacific, reached maximum sustained winds of 184 mph (296 km/h), putting it firmly in Category 5-equivalent territory.
And Champi isn’t just another powerful typhoon.
It has now become the seventh Category 5-equivalent storm recorded around the world this year.
For a time, Champi overtook Hurricane Polo, which had held the title of the strongest tropical cyclone of 2026 based on maximum sustained winds. Polo peaked at 177 mph, meaning Champi edged ahead by roughly 7 mph.
But there is an important wrinkle.
Polo recorded a lower central pressure of 892 millibars, compared with Champi’s 895 millibars. By that measure, Polo remains the more intense storm.
So depending on whether you look at wind speed or atmospheric pressure, the answer to which storm is “strongest” changes.
Champi has also been remarkably persistent.
The storm first reached Category 5-equivalent strength on October 17, shortly after passing near Guam. It weakened somewhat, then regained Category 5 strength the following day — and has since reached that level again.
At its peak, winds near the center were approaching 185 mph.
Why did Champi become so powerful?
The storm found almost perfect conditions for rapid intensification.
Ocean temperatures across the western Pacific have been around 86°F (30°C), providing an enormous supply of heat and moisture. Champi has also been surrounded by deep tropical moisture, relatively light winds aloft and low wind shear.
In simple terms, the environment gave the storm very little standing in its way.
Those conditions allowed Champi to strengthen dramatically in a short period of time, going from a tropical storm to an extremely powerful typhoon in less than two days.
But now the storm is entering a less favorable environment.
Champi is tracking toward Taiwan and is expected to turn northwest before eventually moving toward China and Japan. Forecasters expect it to weaken from Category 5-equivalent strength, potentially falling to the equivalent of a Category 4 or Category 3 storm as it moves farther north.
That does not mean the danger disappears.
Even as Champi weakens, it is expected to remain an extremely powerful system, with typhoon-force winds extending well away from its center.
Taiwan braces for Champi
Taiwan has been preparing for the storm’s arrival, with authorities issuing land and sea warnings as Champi approaches.
The storm’s broad wind field is large enough to affect much of the island, while forecasters are warning of torrential rain, dangerous surf and powerful winds.
More than 100 flights have already been canceled, ferry services have been suspended and tourist attractions have been closed in some areas.
Officials have also been checking drainage systems, flood-control equipment and emergency pumps in areas vulnerable to flooding.
Taiwanese President Lai Ching-te urged residents to prepare early and avoid mountainous and coastal areas.
”A little more preparation means less risk,” he wrote on his Facebook page, according to Reuters.
The storm is also affecting Japan, where airlines have canceled more than 100 flights, disrupting travel for thousands of passengers.
Champi has even forced changes to the major U.S.-Japan military exercise Keen Sword, which involves tens of thousands of personnel.
The U.S. military said training activities were being adjusted day by day to protect participants.
Champi’s influence could reach much farther
The storm’s effects may not stop where the typhoon itself does.
As a massive tropical cyclone moves across the Pacific, it can interact with the jet stream and influence weather patterns much farther downstream.
That could contribute to a more unsettled weather pattern across parts of North America, including Ontario and Quebec, during the middle and latter part of next week.
For now, though, all eyes remain on Champi.
A storm that has already become the fastest-moving name in the race for the world’s strongest tropical cyclone of 2026 is now heading toward Taiwan — and while forecasters expect it to weaken, it is still packing an extraordinary amount of power.
And with nearly 185 mph winds at its peak, Champi has already made its place in the record books.
