Developing Circulation to Pass through the Marianas Early Next Week
The National Weather Service (NWS), Guam Weather Forecast Office continue to monitor a circulation located about 1000 miles east of Saipan near 15 degrees north latitude and 161 degrees east longitude.
The system is currently moving west around 10 mph. At this time, NWS advised model guidance maintains a westward motion to bring the circulation, possibly as a tropical storm, through the Marianas between Saipan and Agrihan Monday night or Tuesday.
Showers and thunderstorms are expected to develop from Tinian northward by Monday, and at Guam and Rota Monday night. Breezy conditions and heavy showers are expected at times Monday night and Tuesday. Stronger winds will also cause seas to build early in the week.
NWS advised there is still quite a bit of uncertainty in how fast it will develop. The Offices of Guam Homeland Security and Civil Defense (GHS/OCD) will continue to monitor the system closely with guidance from NWS and provide updates as needed. The community is advised to heed any additional advisories in the coming days and be prepared to take action, if needed.
