- NEW INFORMATION: A Tropical Storm Warning and Typhoon Watch have been cancelled for the island of Guam and adjacent coastal waters.
-
AREAS AFFECTED: This local statement provides important information and recommended actions for people in Guam and the Northern Marianas.
-
WATCHES/WARNINGS, A Typhoon Warning continues for Rota, Tinian, and Saipan.
Although tropical cyclone watches or warnings are no longer in effect for Guam, possible impacts from related hazards are still a concern.

STORM INFORMATION: At 2 PM ChST,the center of Typhoon Sinlaku (04W) was located near latitude 17.4N,longitude 144.5E. This was about 90 miles west of Alamagan, 95 miles west-southwest of Pagan, 120 miles southwest of Agrihan, 175 miles north-northwest of Saipan and Tinian, and 270 miles north of Guam. Storm motion was north, 355 degrees, at 4 mph. Storm intensity was 115 mph.
-
SITUATION OVERVIEW: The eye of Typhoon Sinlaku (04W) is moving slowly north and the eye is well north-northwest of Tinian and Saipan. Latest satellite imagery indicates that the storm center has just begun to shift toward the north-northeast. Typhoon Sinlaku has been slow to move out, and the TS wind field has expanded since earlier this morning. This kept the northern coastal waters of Guam just within the tropical storm force winds until just earlier this afternoon, and Saipan and Tinian are now just outside of the outer edge of the destructive tropical storm winds. Typhoon Sinlaku is now moving through the northern CNMI just west of Alamagan, Pagan, and Agrihan. As Sinlaku moves through the northern CNMI today and tonight, it is forecast to curve further to the northeast, passing north of Agrihan Friday.

People should remain in a designated shelter or in a sturdy and reinforced concrete building to ride out the storm as tropical storm force winds are occurring at Rota, Tinian, and Saipan. Due to the size of the storm, the latest forecast has tropical storm force winds continuing at Rota for the next few hours this afternoon, and very late tonight for Tinian and Saipan. Even when winds start to decrease, remain indoors until the "all clear" is given. Strong to tropical storm force gusts remain a possibility for the next day or two, especially with any passing shower.
Destruction of remaining metal roof homes remains possible. Electricity and water will remain unavailable for days and perhaps weeks after the storm passes. Most trees will be snapped or uprooted. Fallen trees may cut off residential areas for days to weeks.
Stay indoors during heavy rain and windy conditions associated with Typhoon Sinlaku (04W). The window of time to complete preparations for the protection of life and property has closed. Find shelter to ride out the storm. Remain in a sturdy shelter until the "all clear" is given. Heed the advice of your local emergency managers and officials, and continue to monitor forecasts by your local National Weather Service office in Tiyan, Guam.
-
WIND INFORMATION: Northeasterly tropical storm force winds around 65 mph are expected this evening with typhoon winds around 75 mph possible as Sinlaku passes to the west, and winds shift towards the southeast. The size of the storm and overall storm motion will maintain southeast tropical storm winds through Friday afternoon as Sinlaku continues on its accelerated northward trek after exiting the Marianas later in the week.
-
COASTAL INUNDATION AND SURF INFORMATION, Seas of 20 to 30 feet remain possible, with dangerous surf and significant coastal inundation and beach erosion possible.
-
OTHER STORM EFFECTS: Heavy, intense rainfall with TY Sinlaku is likely tonight and Friday, bringing additional rainfall amounts of 4 to 6 inches by the weekend, with rainfall amounts upwards of 10 to 15 inches near the center, as the system moves across the northern CNMI. The exact track of Sinlaku will determine where the heaviest rainfall will set up across the islands.

WHAT: For the Coastal Flood Warning, significant coastal flooding of 5 to 8 feet. For the High Surf Warning, dangerously large breaking waves of 16 to 20 feet. For the Coastal Flood Advisory, minor coastal flooding of 1 to 2 feet expected. For the High Surf Advisory, large breaking waves of 10 to 14 feet expected. For the High Rip Current Risk, dangerous rip currents.
-
WHERE: South, west and north facing reefs and shorelines of Tinian and Saipan.
-
WHEN: For the Coastal Flood Warning, until noon ChST Friday. For the High Surf Warning, until 5 PM ChST Friday. For the Coastal Flood Advisory, from noon Friday to 5 PM ChST Saturday. For the High Surf Advisory, from 5 PM Friday to 5 PM ChST Saturday. For the High Rip Current Risk, through Saturday afternoon.
-
IMPACTS: Numerous roads may be closed. Low lying property including homes, businesses, and some critical infrastructure will be inundated. Some shoreline erosion will occur. Breaking waves can sweep people off jetties and docks, and into dangerous seas. Life- threatening swimming conditions and significant beach erosion can be expected. Rip currents can sweep even the best swimmers away from shore into deeper water.
-
ADDITIONAL DETAILS: As TY Sinlaku continues to move away and wind driven waves decrease, the primary swell and highest surf will become southwest. Seas will be slow to subside over the next couple of days.
