Super Typhoon Sinlaku Batters Saipan and Tinian With 150 mph Winds; Guam Hit by Flash Flooding
Super Typhoon Sinlaku slammed into the Northern Mariana Islands overnight, ripping across Tinian and Saipan with sustained winds near 150 mph as its inner eyewall passed around 10:15 p.m. local time. The storm had earlier peaked over open water near 180 mph and carried an expanded wind field — typhoon‑force gusts out to roughly 80 miles and tropical‑storm‑force winds as far as about 275 miles — producing prolonged destructive conditions as it slowed near the islands. Guam missed a direct eyewall hit but received torrential rain, flash flooding and tropical‑storm‑force gusts (reported between about 60–80 mph), with many businesses closed, schools canceled and authorities urging residents to shelter while military personnel were ordered to prepare and shelter in place.
On Saipan and Tinian crews and residents reported extensive structural damage: metal roofs ripped off, wooden and tin buildings collapsed, cars overturned, balcony railings torn away and water intrusion even into concrete homes. More than 1,000 people are being sheltered across Guam and the Northern Marianas by the American Red Cross, and local officials say there have been no reported deaths so far even as searches and rescues remain difficult in the storm’s aftermath. Federal response was activated quickly — the president approved emergency declarations for Guam and the Northern Marianas and FEMA is coordinating support, dispatching nearly 100 staff along with EPA, DOT and Army Corps of Engineers personnel — though officials acknowledge logistics are complicated by ongoing federal constraints. The islands’ vulnerability is accentuated by local building stock: historically about 56.5% of occupied homes in the commonwealth have concrete roofs while roughly 41.8% have metal roofs, the latter far more prone to catastrophic wind damage; scientists also note a broader trend of climate change contributing to stronger storms in the region.
Early reporting emphasized Sinlaku’s intensity and the precautionary warnings that put the region on high alert, but coverage shifted as first‑hand accounts and damage assessments arrived. Initial dispatches focused on watches, warnings and the storm’s peak metrics, while later reporting from outlets providing on‑the‑ground reporting — including ABC, NPR, PBS and The New York Times — documented the scale of destruction on Saipan and Tinian, firsthand eyewitness descriptions and the difficulties responders face. Social media and officials’ feeds reflected that evolution: the Department of Homeland Security publicly thanked the president for rapid declarations and FEMA engagement, meteorologists warned of potentially catastrophic impacts to infrastructure, volunteers and Red Cross teams posted about deploying to the region, and local outlets noted the governor keeping Guam at a high state of readiness amid ongoing dangerous seas and winds.

📌 Key Facts
- Super Typhoon Sinlaku became the strongest tropical cyclone on Earth so far in 2026, peaking at about 180 mph over the open ocean, later stabilizing near 175 mph, and producing sustained winds around 150 mph as it crossed Saipan and Tinian.
- Sinlaku slowed and nearly stalled as it approached the Marianas (at one point about 30 miles offshore), and its inner eyewall moved over Tinian and Saipan overnight, prolonging destructive winds and rains and prompting NWS warnings that many residents "will wake up to a different island."
- Saipan and Tinian suffered extensive structural damage — tin roofs torn off, wooden and tin buildings collapsed, cars flipped or stacked, balcony railings torn away, and water intrusion even into concrete homes — though local officials reported no confirmed deaths so far.
- Guam avoided a direct eyewall hit but experienced torrential rain, flash flooding, widespread power outages, and tropical‑storm‑force gusts (reports of gusts up to about 80 mph), with schools closed, military personnel ordered to shelter in place, and forecasts calling for dangerous winds (75+ mph) to persist into Wednesday.
- Warnings and watches covered the region: typhoon warnings for Rota, Tinian and Saipan (extended to islands including Alamagan, Pagan and Agrihan in some updates), a tropical‑storm warning and typhoon watch for Guam, and a large wind field with typhoon‑force winds extending roughly 80 miles from the center and tropical‑storm‑force winds out to about 275 miles.
- Federal and relief response mobilized: President Donald Trump approved emergency disaster declarations for Guam and the Northern Mariana Islands; FEMA is coordinating multi‑agency support and dispatching nearly 100 staff plus EPA, DOT and U.S. Army Corps personnel; and the American Red Cross is sheltering more than 1,000 people across Guam and the Northern Marianas.
- Officials say emergency response functions are continuing despite an ongoing Department of Homeland Security shutdown — FEMA reports more than 10,000 disaster personnel remain paid and roughly $3.6 billion remains in the disaster relief fund while military and FEMA assets are being staged in the region.
