Destructive winds of 115–135 mph threatened far southern Guam early Sunday, October 18, as the National Weather Service issued an [extreme warning](https://forecast.weather.gov/wwamap/wwatxtget.php?cwa=gum&wwa=all&ref=theamericanquorum.com) and said radar showed Typhoon Champi’s northern eyewall moving ashore. The alert, issued Saturday afternoon in the eastern United States, marked an immediate threat to residents of the U.S. territory as the Category 4 storm approached.

The warning identified Talofofo, Inarajan, Merizo, Santa Rita and Umatac and ran through 5:30 a.m. Chamorro Standard Time, equivalent to 3:30 p.m. Eastern Daylight Time on October 17\. Forecasters anticipated significant to catastrophic damage, particularly to buildings not constructed of concrete. Those statements describe the agency’s forecast and radar assessment; they are not a completed damage survey or confirmation that every listed community has experienced those wind speeds.

## Residents told to take cover

The Weather Service instructed residents to shelter in a reinforced interior room away from windows. People in buildings that are not fully concrete were advised to get beneath sturdy furniture and protect their heads and bodies with mattresses, blankets or pillows. The immediate instruction was to remain protected throughout the dangerous conditions.

Guam had already moved into Condition of Readiness 1 at 1 p.m. Saturday local time under Gov. Lourdes A. Leon Guerrero’s [readiness order](https://ghs.guam.gov/jic-release-no-7-guam-cor-1-typhoon-champi-update-ahaws-sirens-be-used-during-champi-additional?ref=theamericanquorum.com). That government notice directed residents to remain indoors until Condition of Readiness 4\. Joint Region Marianas and its installations were scheduled to enter their corresponding cyclone readiness condition at 3 p.m., extending preparations across civilian and military facilities.

## An offshore eye still brings danger

Champi’s maximum sustained winds had reached 140 mph as it neared Guam, according to [Scripps reporting](https://www.wtvr.com/weather/guam-braces-for-category-4-typhoon-champi-as-eyewall-approaches?ref=theamericanquorum.com) citing the Weather Service. The forecast placed the center south of the island while bringing the eyewall into southern Guam. The center’s track therefore offered no assurance that communities would escape destructive conditions: the eye and the surrounding belt of severe weather are different parts of the storm.

In an early Sunday [KPRG report](https://www.islapublic.org/news/2026-10-18/nws-worst-of-champis-weather-will-be-from-sunrise-to-late-morning-sunday?ref=theamericanquorum.com), Weather Service forecaster Brandon Aydlett said the worst weather was expected from sunrise into late morning. Severe typhoon winds were then expected to ease, but heavy rainfall would continue. That distinction matters for residents waiting to assess their homes: the end of the strongest winds would not mean the end of dangerous weather.

The agency’s earlier [forecast discussion](https://beta.weather.gov/tools/afd/gum/7fa89883-4c10-430f-ba72-d517cbba8901/?ref=theamericanquorum.com) also described a substantial coastal flooding threat, with potential inundation of 5–7 feet on Guam and landslides capable of closing roads. It said impacts on western coasts depended heavily on the final track. These were projected hazards, with the greatest exposure varying by location rather than a uniform outcome across the island.

The Weather Service attributed the strengthening environment to warm sea surface temperatures and weak wind shear in its Saturday evening discussion. It also warned that a northward shift could expose central and northern Guam to worse conditions. The forecast’s sensitivity to small changes in track helps explain why an expected offshore passage was accompanied by urgent instructions to remain in sturdy shelter.

## Shelter capacity already under strain

Guam’s Joint Information Center reported at 10 p.m. Saturday that the Astumbo Elementary School evacuation center had reached [full capacity](https://ghs.guam.gov/jic-release-no-10-astumbo-elementary-school-emergency-evacuation-center-full-capacity?ref=theamericanquorum.com). The same bulletin cautioned that dangerous conditions would persist well into Sunday, beyond the storm’s expected closest approach. It reiterated the instruction to remain inside a sturdy, concrete-reinforced structure until officials announced Condition of Readiness 4.

The [Red Cross](https://www.redcross.org/about-us/news-and-events/news/2026/tropical-cyclone-heads-to-the-islands.html?ref=theamericanquorum.com) said in its October 16 response update that more than 150 disaster responders had volunteered to travel to the islands. Almost 90 were already there and as many as 70 more were en route at the time of that update. The organization was preparing to operate or support up to 13 shelters, working with local chapters, officials and community partners.

## A third storm during an unfinished recovery

The Red Cross described Champi as the region’s third major storm threat since April, following Sinlaku and July’s Bavi. It said many families were still living in tents that had to be dismantled ahead of the new storm, forcing another search for shelter with relatives, friends or emergency facilities. Scripps also reported the continuing recovery and the displacement risk, underscoring that the new emergency was arriving before earlier housing losses had been resolved.

For residents, the next milestone is the official all-clear, rather than a temporary lull or the storm center’s closest passage. The Red Cross advises staying indoors, avoiding beaches and riverbanks, and never walking, swimming or driving through floodwater. It also recommends battery lighting rather than candles during outages, while local officials continue directing residents to remain sheltered.
