Based on information received from the National Weather Service in Tiyan, Guam, and compiled at the CNMI Emergency Operations Center-State Warning Point based on the latest visible satellite loop, a tropical disturbance centered about 110 miles northeast of Saipan is moving west-northwestward at about 15 mph.
A tropical disturbance is found east of the CNMI.
This disturbance is the subject of a tropical cyclone formation alert issued by the Joint Typhoon Warning Center. Development is anticipated to be slow and no damaging winds are expected for the Mariana Islands at this point. It should pass just north of Saipan last night and this morning.
Scattered heavy showers and isolated thunderstorms and gusty winds are expected to move into Saipan and Tinian waters late yesterday afternoon and then over the islands last night. Showery weather was expected over Rota and Guam last night. Once this system has pulled west of the Mariana Islands on Thursday afternoon, a monsoon pattern will likely develop and prolong the wet weather through Friday.
While this disturbance is not expected to bring tropical storm conditions to the Marianas, the EOC is advising residents of Saipan, Tinian, and Rota to maintain necessary precautionary measures for gusty winds and heavy rain showers and to also stay informed on the latest statements and advisories which will be available through local media sources and NOAA weather radio broadcast on 162.5 megahertz, or call the EOC at 237-8000 or 664-8000, and for the Northern Islands to contact the EOC at high frequency single side band radio on frequency 5.205.0.
