Super Typhoon Sinlaku continued its north-northwest march toward the Marianas at 10 mph early Monday, with the latest forecast track shifting the storm’s center closer to Tinian and Saipan, according to a 5 a.m. ChST National Weather Service Guam Forecast Office advisory.
A Typhoon Warning remains in effect for Rota, Tinian and Saipan, with damaging winds expected this evening or tonight. Guam remains under a Tropical Storm Warning, with winds of 39 to 73 mph also expected this evening or tonight.
The northward shift prompted watches for the far northern islands, with Pagan and Alamagan now under a Tropical Storm Watch as winds of 39 to 73 mph are possible within 48 hours. Ulul in Chuuk State remains under a Tropical Storm Warning and Typhoon Watch as Sinlaku gradually departs that area.
Officials warned that damaging winds, heavy rainfall and dangerous seas are still expected across all of the Marianas regardless of the track shift. The arrival of Sinlaku at the Marianas is possible between late tonight and Wednesday morning, though that window remains subject to change.
Residents are urged to finish storm preparations immediately.
The National Weather Service Guam will host a Facebook Live at 8:30 a.m. with the latest information. Updates are available at weather.gov/gum.
