Here’s the latest on Tropical Storm Sinlaku, based on recent official updates.
- The U.S. Coast Guard and U.S. Navy crisis management channels have been signaling that Sinlaku could intensify to typhoon strength and affect the Mariana Islands (Guam, CNMI) with strong winds, heavy rain, and dangerous seas through the weekend into early next week. This includes warnings to secure vessels, prepare coastal areas, and monitor conditions closely.[2][6]
- Tracking maps and JTWC advisories from early April indicate a potential close approach to Guam, with wind gusts and coastal impacts possible starting Sunday and increasing through Monday night into Tuesday, though forecasts carry uncertainty and can shift with new data.[3][2]
- Local weather services in the region have issued warnings and advisories, including Small Craft Advisories, rip current statements, and high surf warnings, emphasizing a dangerous maritime environment and the need for residents to stay off beaches and secure outdoor items.[2][3]
- Public-facing updates from media and official trackers show Sinlaku was monitored as it intensified from a tropical depression to a tropical storm, with potential pathways varying but generally favoring a northward or northwestward track toward the Marianas and possibly toward the Philippine Sea region in subsequent days.[4][9][3]
Illustration: A typical sequence during approaching storms in this region includes (1) tropical cyclone formation and upgrading to tropical storm, (2) a period of intensification near or north of Chuuk or Palau, (3) potential close approach to Guam/CNMI with increasing wind and sea conditions, and (4) escalating warnings and port/ship movement controls as PHWC conditions are activated.
What you should do now if you’re in the area
- Monitor official sources continuously (National Weather Service Guam, JTWC, local civil defense), as advisories can change rapidly.
- Follow port and maritime guidance: secure vessels, limit coastal activities, and heed warnings for high surf, rip currents, and possible port closures.
- Prepare emergency supplies in case of power outages or flooding, including water, nonperishable food, flashlights, and a battery-powered radio.
