The National Weather Service advises that wet and windy weather will persist across the Marianas for the next several days.
The NWS reports that an active monsoon pattern is generating numerous scattered showers and isolated thunderstorms.
Although there are no tropical cyclones that pose a direct threat to the Marianas at this time, brief flooding is possible, especially over poor drainage areas.
The following NWS advisories remain in effect:
Flash flood watch
A flash flood watch is in effect for Guam, Rota, Tinian and Saipan through Wednesday night.
Locally, heavy showers associated with a surge in southwest monsoon winds may produce flash flooding in the Marianas for the next couple of days.
High surf advisory
A high surf advisory remains in effect for Guam, Rota, Tinian and Saipan through Friday night, meaning high surf will affect beaches in the advisory area, producing localized beach erosion and dangerous swimming conditions.
Surf will remain hazardous at levels of 11 to 14 feet along west-facing reefs and 7 to 10 feet along south-facing reefs for the next few days.
Avoid venturing out along reefs and beaches, especially those facing south and west. Large breaking waves can knock people down and cause serious injuries. Strong rip currents will be life-threatening.
Small craft advisory
A small craft advisory remains in effect for Guam, Rota, Tinian and Saipan coastal waters through Friday night, meaning wind speeds and heavy seas are expected to produce wave conditions hazardous to small craft.
Southwest winds at 19 to 29 mph with occasional gusts up to 34 mph are expected. Seas of 10 to 13 feet will continue through Friday night. Inexperienced mariners, especially those operating smaller vessels, should avoid sailing in these conditions.
As school preparations are underway for many across the community, Guam Homeland Security/Office of Civil Defense advises residents and visitors to be careful when traveling in rainy conditions. Drive slowly and allow enough braking distance between you and the vehicle in front of you.
Avoid the ocean, especially south- and west-facing reefs and beaches until hazardous conditions subside.
