The National Weather Service Guam Weather Forecast Office is reporting that Tropical Depression 20W is now a Tropical Storm code-named Hagibis.
At 7 a.m., Tropical Storm Hagibis was located about 750 miles east of Saipan, moving west at 17 mph with maximum sustained winds now up to 40 mph.
Tropical Storm Hagibis is expected to continue westward with a gradual turn toward the west-northwest on Monday.
According to NWS, Hagibis will continue to strengthen and could become a typhoon on Monday as it approaches the northern islands of the CNMI.
A typhoon watch remains in effect for Alamagan Island, meaning typhoon conditions, including destructive winds of 74 mph or more, are possible within 48 hours, around Monday evening.
A tropical storm watch remains in effect for all the remaining islands of the CNMI, including Rota, Tinian and Saipan. This means, tropical storm conditions, including damaging winds of 39 mph or more, are possible within 48 hours, around Monday afternoon.
A hydrologic outlook has been issued for Tinian and Saipan due to the possibility of 5 to 8 inches of rainfall in the next couple days. Localized flooding will be possible in low-lying and poor drainage areas.
For Guam: watches and warnings are not in effect. Tropical Storm force damaging winds are expected to keep north of Guam at this time.
But NWS said it will be watching closely for any shifts north or south that could bring the possibility of damaging winds closer to Guam and as the tropical storm approaches, NWS may upgrade its watches to warnings later this afternoon.
According to GHS/OCD public information officer, Jenna Blas, they 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.
