Wet and Windy Conditions Persist Across the Marianas

The National Weather Service (NWS), Guam Weather Forecast Office advised wet and windy weather will persist across the Marianas as an active monsoon pattern generates 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:

A flash flood watch is in effect for Guam, Rota, Tinian, and Saipan through Wednesday night. Locally heavy showers associated with a surge in the southwest monsoon winds may produce flash flooding in the Marianas the next couple of days. Flash flooding could become life-threatening very quickly.

Residents and visitors are advised to take precautionary actions:

Turn Around, Don’t Drown. Immediately move to higher ground if flash flooding occurs. Water levels can rise rapidly and sweep people away. Avoid walking or driving through flood waters. Just 6 inches of moving water can knock you down, and 2 feet of water can sweep your vehicle away
Stay away from storm drains, culverts, creeks, and streams.
If floodwaters rise around your car but the water is not moving, abandon the car and move to higher ground. If the water is moving, do not leave the car.
Avoid camping, parking, or hiking along streams, rivers, and creeks while the advisories are in place. These areas can flood quickly and with little warning.

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 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.

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 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, the Offices of Guam Homeland Security and Civil Defense (GHS/OCD) advise residents and visitors to practice extreme caution while traveling in rainy conditions, driving below the speed limit and allowing enough braking distance between vehicles. Avoid the ocean, especially south and west facing reefs and beaches until hazardous conditions subside. Heed the advice of lifeguards, beach patrol flags, and signs.

X Flooding is a temporary overflowing of water onto land that is normally dry. Flooding may happen with only a few inches of water, or it may cover a house to the rooftop. There are many possible causes of floods including heavy rain, coastal storms and storm surge, waterway overflow from being blocked with debris, or overflow of levees, dams, or waste water systems. Flooding can occur slowly over many days or happen very quickly with little or no warning, called flash floods.
