Monster Typhoon in Pacific Ocean Bearing Down on Group of Remote US Islands

A dangerous super typhoon in the Pacific Ocean is barreling toward a group of remote U.S. islands.

Super Typhoon Sinlaku is expected to make landfall Tuesday in the Northern Mariana Islands and bring destructive winds, widespread heavy rain, and flooding, the National Weather Service said Monday.

Guam, a U.S. territory with American military installations and about 170,000 residents, also could see damaging winds beginning Monday and is under a tropical storm warning. The U.S. Coast Guard issued flood and high wind warnings over the weekend.

The tropical typhoon — the strongest on Earth so far this year — was producing sustained winds of 173 mph (278 kph) on Monday as it neared the islands of Rota, Tinian, and Saipan, according to the Joint Typhoon Warning Center.

While it's expected to weaken slightly over the next few days, Sinlaku should cross near the islands as a Category 4 or 5 typhoon.

About 50,000 people live on the three islands, with most on Saipan, known for its laid-back resorts, snorkeling, and golf as well as the capital of the Northern Mariana Islands.

In Guam, where Typhoon Mawar knocked out power for days in 2023, U.S. military officials warned personnel to prepare for the storm and shelter in place. The island is an important hub for U.S. forces in the Pacific.

President Donald Trump on Saturday approved emergency disaster declarations for Guam and the Northern Mariana Islands, allowing for additional help with emergency services.

A super typhoon is a name given to the strongest tropical cyclones that brew in the northwestern Pacific Ocean, where Earth’s most intense storms usually form.

Monitored by the Joint Typhoon Warning Center in Guam, super typhoons are the equivalent of category 4 or 5 hurricanes in the Atlantic, with winds of at least 150 mph (240 kph). There have been more than 300 super typhoons identified since the warning center started using that name nearly 80 year ago.
