Super Typhoon Sinlaku Threatens Guam, Marianas with 173 mph Winds

Super Typhoon Sinlaku — the strongest storm on Earth so far this year — was churning toward U.S. territories in the Pacific early Tuesday with sustained winds of 173 mph, threatening to devastate some 50,000 residents across three remote islands while raising urgent questions about federal disaster readiness under a prolonged government shutdown.

The storm, on track to make landfall over the Northern Mariana Islands of Rota, Tinian and Saipan late Tuesday local time, was expected to arrive as a Category 4 or 5 system, according to the Joint Typhoon Warning Center in Guam. Guam — a U.S. territory of about 170,000 residents and home to critical American military installations — was already being battered by heavy rain and wind gusts up to 60 mph very early Tuesday, with most businesses shuttered and residents ordered to stay home, said Joshua Schank, a lead meteorologist with the National Weather Service in Guam.

For Treasure Coast residents who lived through the grinding uncertainty of hurricane season, Sinlaku's approach carries a familiar dread — and a pointed federal stress test. FEMA, which would be the lead agency for any major disaster response along Florida's coast, is operating under the record-long Department of Homeland Security funding impasse. The agency's disaster relief fund held approximately $3.6 billion as of late March, officials said, and more than 10,000 disaster personnel remain on the payroll — but those reserves are finite.

President Donald Trump on Saturday approved emergency disaster declarations for both Guam and the Northern Mariana Islands. FEMA said it is dispatching nearly 100 staff to the region alongside personnel from the Environmental Protection Agency, the Department of Transportation and the U.S. Army Corps of Engineers. "We are ready to respond to this event," FEMA regional administrator Robert Fenton said from Guam on Sunday.

Super typhoons are the northwestern Pacific equivalent of Category 4 or 5 Atlantic hurricanes, with sustained winds of at least 150 mph. Sinlaku is the strongest such storm identified worldwide in 2026, according to public documents from the Joint Typhoon Warning Center. Saipan, the most heavily populated of the three threatened islands, was the site of one of World War II's deadliest Pacific battles.

The storm is expected to cross or skirt Tinian and Saipan before potentially weakening over open water. Officials have not confirmed a projected date for any all-clear declaration. [NEEDS VERIFICATION: post-landfall track and weakening timeline beyond initial NWS forecast window]
