Super Typhoon Champi moved just south of Guam, bringing a northern eyewall close enough to graze the island's southern tip but sparing it the worst destruction. The Joint Typhoon Warning Center assessed peak sustained winds at 165 miles per hour after Champi intensified from an initial 150 mile per hour analysis.
Radar and satellite analyses showed a compact, violent eyewall as the storm tightened its core, followed by an eyewall replacement cycle that reduced peak winds to about 140 miles per hour. The JTWC said that exceptionally favorable conditions along Champi's track, including light to moderate wind shear, ample moisture, strong upper level outflow, and unusually warm sea surface temperatures near 29 to 30 degrees Celsius, support the possibility of reintensification to Category 5 strength.
Guam's population of about 170,000 relies on long experience with typhoons and emergency response. NOAA imagery captured the storm's passage and forecasters warned coastal areas along the likely track to prepare for very strong winds and heavy rains. The storm was projected to track west northwest toward the vicinity of Taiwan later in the week, according to JTWC forecast guidance.
Regional Impact And Broader Storm Context
Champi is one of several very intense tropical cyclones recorded this season. Yale Climate Connections reported that Champi is among at least eight Category 5 cyclones globally this year, with a possible ninth pending postseason analysis of another storm. The outlet noted a long term rise in the fraction of tropical cyclones reaching Category 4 or 5 strength since accurate satellite records began.
Other major storms this season included Hurricane Polo in the eastern Pacific, which reached roughly 180 miles per hour and later made landfall on Mexico's Baja Peninsula as a lower category storm, causing fatalities and more than one hundred million dollars in reported damage. Central and western Pacific storms of note included Super Typhoon Bavi, which passed very near Rota and left severe destruction according to the island's mayor, and Super Typhoon Sinlaku, which caused multiple fatalities and reported economic losses in the Northern Mariana Islands and Guam.
The National Hurricane Center signaled continued activity in the Eastern Pacific, assigning high odds to a developing disturbance off Central America and monitoring a separate coastal low off the US East Coast with a moderate chance of subtropical development. Forecasters warned that coastal flooding and elevated waves remain the primary hazards for the Atlantic coast in that scenario, while ensembles suggest the core is unlikely to move onshore.
