Earlier forecast and background

Super Typhoon In-fa (30W) is approaching the Northern Mariana Islands. The U.S. National Weather Service (NWS) has issued a Typhoon Warning for Agrihan, Pagan and Alamagan. Its 2:27 a.m. ChST October 30, 2026 local statement reports maximum sustained winds of 150 mph (approximately 241 km/h) near the storm center. This is the cyclone’s central intensity, not a measured wind speed at every island.
Track and forecast timing
At 1 a.m. ChST on October 30, the center was near 16.9°N, 150.4°E, about 305 miles (491 km) east of Alamagan, moving west at approximately 18 mph (29 km/h). NWS forecasts a gradual turn toward the northwest, with the center potentially passing close to or over Agrihan during the evening of October 30, local time. The forecast is subject to change and does not establish that landfall has occurred.
Destructive wind, coastal flooding and heavy rain risk
For Agrihan, NWS forecast possible 110–130 mph (177–209 km/h) destructive winds, with gusts up to 180 mph (290 km/h) near the storm’s center. Pagan and Alamagan may experience damaging winds as well. The agency warned of possible 30–40-foot surf (9–12 m), 3–6 feet (0.9–1.8 m) of coastal inundation in the areas nearest the center, and 8–12 inches (200–305 mm) of rainfall through Saturday. These are forecasts, not confirmed damage measurements.
What does a Typhoon Warning mean?
A Typhoon Warning means winds of at least 74 mph are expected and damaging tropical-storm-force winds of at least 39 mph may begin within 24 hours. NWS urged residents to complete preparations, secure loose objects, identify appropriate shelter, and stock water, food and medication. Follow local emergency management instructions and current NWS Guam updates.
