The National Weather Service (NWS), Guam Weather Forecast Office continue to closely monitor Tropical Depression 01W, which is now moving north-northwest.
As of 7 a.m., 01W was located near latitude 4.7 degrees north and longitude 174.1 degrees east, about 260 miles southeast of Majuro and 2,090 miles east-southeast of Guam, moving north-northwest at 7 mph with maximum sustained winds of 30 mph. A tropical storm watch remains in effect for Majuro and Kwajelein in the Republic of the Marshall Islands, meaning damaging winds of 39 mph or more are possible within 48 hours.
There are no watches or warnings in effect for Guam or the CNMI.
NWS advised there is still quite a bit of uncertainty as to the track, timing, and strength by the time it reaches the vicinity of the Marianas later this week. It is still early to tell what impact, if any, it will have on Guam or the Marianas.
While there is no immediate threat to Guam or the Marianas at this time, 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.
NWS advised large swell will continue to produce hazardous sea conditions for the Marianas. The following advisories remain in effect:
A high surf advisory is in effect for Guam, Rota, Tinian, and Saipan until 6 p.m. this evening, meaning high surf will affect beaches in the advisory area, producing localized beach erosion and dangerous swimming conditions. Hazardous surf of 7 to 10 feet along north facing reefs and surf 7 to 9 feet along east facing reefs are expected.
A high risk of rip currents is in effect for Guam, Rota, Tinian, and Saipan through Tuesday afternoon. Rip currents are powerful channels of water flowing quickly away from shore. If caught in a rip current, yell for help. Remain calm and stay afloat while waiting for help. If swimming out of a rip current, swim parallel to shore and back toward the beach when possible. Do not attempt to swim directly against a rip current. Rip currents will be life threatening.
A beach hazards statement is in effect for Guam, Rota, Tinian, and Saipan. Portugese man-o-war have been reported washing up on local beaches including the east coast at Ipan and on the west coast at both Piti and Tumon. They are likely to continue washing up over the next few days. Man-o-war can inflict a painfull sting even after they have died. Remain watchful and avoid touching them. Closed toe shoes are recommended if by the beach.
The community is reminded to heed the advice of lifeguards, beach patrol flags, and signs.
A small craft advisory is in effect for Guam, Rota, Tinian, and Saipan coastal waters until 6 p.m. Tuesday. Northeast winds of 10 to 20 knots with frequent gusts to 25 knots and combined seas of 8 to 11 feet will produce hazardous conditions for operators of small craft. Inexperienced mariners, especially those operating smaller vessels, should avoid sailing in these conditions.
The Offices of Guam Homeland Security and Civil Defense GHS/OCD advise residents and visitors to avoid the waters until hazardous conditions subside.
