Tropical Storm Goni Changed Its Track


Goni is now expected to pass in between Rota and Tinian Sunday morning but possibilities are open for Goni to pass closer to Guam and Rota.


Guam – “Tropical Depression 16W now (is) now Tropical Storm Goni,” the National Weather Service wrote in its latest Public Advisory (#4).


This storm is currently moving towards west-northwest at about 9 miles per hour and is expected to slowly change its direction to northwest with no change in forward speed. Such action will take Goni to pass between Rota and Tinian around Sunday morning. But NWS writes, “However any delay on the northwest turn would take it closer to Guam and Rota instead.”


As of 7 AM (CHST), Goni was located about 13.2N 147.6E, which is about 180 miles southeast of Saipan, and 190 miles east of Guam. Its Maximum Sustained Winds increased to 40 miles per hour and is expected to continue to increase over the next few days. Tropical Storm Goni may become a typhoon late Sunday night or Monday morning.


As tropical storm conditions are likely within 24 hours, NWS issued Tropical Storm Warning for Rota, Tinian, and Saipan. Typhoon Watch–which is issued when typhoon conditions are possible within 36 hours–remains in effect for Tinian and Saipan. Currently Guam is under Tropical Storm Watch, as tropical storm conditions are anticipated within 36 hours.


The National Weather Service also updated another hydrologic outlook this morning to inform that Guam and Rota may see about 3 to 6 inches of rainfall while 4 to 8 inches are expected for Tinian and Saipan.“These rainfall amounts can cause flooding in urban and low-lying areas…near streams and rivers and areas with poor drainage. Use caution when traveling and be prepared to protect property. Emergency management offices and utility companies may also need to make special preparations,” NWS warns.
