Guam just dodged a catastrophe by about ten miles — and the storm that spared it is now hunting the title of the strongest tropical cyclone on Earth in 2026.
Ten miles from disaster
Typhoon Champi was upgraded to super typhoon status just as its eye passed about 10 miles south of Guam's southern tip at 4:26 on Sunday morning, with sustained winds of 150 mph — the super typhoon threshold and the high end of Category 4 (Category 5 begins at 157 mph). The eye was only about 5 miles wide, and winds fell off sharply within 10 to 15 miles of the centre.
That narrow miss is the entire story of Guam's weekend. Most of the island experienced tropical-storm winds with typhoon-force gusts instead of the feared direct hit: gusts at the airport reached 80 to 85 mph, and rainfall totalled 1 to 3 inches rather than the predicted 8 to 14. "It's really hard to underscore how close this was to being a significant and devastating event," said Brandon Aydlett, science and operations officer at the National Weather Service in Tiyan. Had the tiny, tightly packed core come ashore, he said, it would have been devastating.
How it got so strong, so fast
Champi's maximum sustained winds roughly doubled from 110 to 220 km/h in just 24 hours as it approached Guam — a textbook case of rapid intensification. The ingredients were all present: sea surface temperatures around 30°C, deep atmospheric moisture, calm upper-level winds, and enough high-altitude ventilation to exhaust air away from the storm's top. The system is currently moving west-northwest over some of the warmest, highest-heat-content waters in the western Pacific.
Forecasters expect Champi to re-attain super typhoon intensity within about 12 hours and peak near 260 km/h. If it keeps strengthening, it would become the world's seventh Category 5 storm of 2026 — and remarkably, all six previous ones formed over the Pacific: Sinlaku, Bavi and Dolphin in the west; Genevieve, Lowell and Polo in the east. Hurricane Polo currently holds 2026's strongest-storm crown at 285 km/h with a central pressure of 892 millibars, the second-most intense hurricane ever recorded in the eastern Pacific. Champi could dethrone it.
What's next — and why this season matters
Champi's forecast track keeps Taiwan, the Batanes and Babuyan islands, and northern Luzon on watch, with longer-range possibilities including a strong landfall anywhere from China to Taiwan or southern Japan. An eyewall replacement cycle — where a storm's inner wall collapses and a wider one forms — has just completed, which often precedes another round of strengthening.
The bigger picture is the season itself. Champi is provisionally the 30th storm of an unusually active 2026 western Pacific typhoon season, and the clustering of Category 5 storms is exactly the kind of pattern climate scientists watch closely: warmer oceans hold more energy, and storms are converting it faster.
