An urban and small stream flood advisory is in effect for Guam until 1 p.m. Two inches of rain has already fallen and an additional 1 to 2 inches is expected, resulting in continued flooding of low-lying and poor drainage areas, and near rivers and streams. The worst flooding will be in the southern half of the island at Inarajan, Asan, Piti, Santa Rita, Umatac, and especially Merizo.
Residents and visitors are advised to take precautionary actions:
· Clear drainage areas and un-block clogged storm drains in your area to minimize the chance of flooding.
· Turn Around, Don’t Drown. 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.
· If there is a chance of flash flooding, move immediately to higher ground.
· 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 during heavy rainfall. These areas can flood quickly and with little warning.

A high surf advisory is in effect for Guam, Rota, Tinian, and Saipan until 6 a.m. Wednesday, meaning high surf will affect beaches in the advisory area, producing localized beach erosion and dangerous swimming conditions. Surf will build and reach hazardous heights of 8 to 11 feet this afternoon along south and west facing reefs. Surf heights are expected to increase between 10 and 14 feet tonight. Avoid venturing out along south and west facing reefs and beaches. Large breaking waves can knock people down and cause serious injuries. Strong rip currents will be life threatening.
A small craft advisory is in effect for Guam, Rota, Tinian, and Saipan coastal waters until 6 a.m. Wednesday, meaning wind speeds and heavy seas are expected to produce wave conditions hazardous to small craft. Southwest winds will increase to 19 to 24 mph with frequent gusts to 29 mph and occasional gusts to 34 mph this afternoon. Seas will build to 8 to 10 feet this afternoon. 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 practice extreme caution while traveling in rainy conditions, driving below the speed limit and allowing enough braking distance between vehicles. If near the ocean, avoid south and west facing reefs and beaches until hazardous conditions subside. Heed the advice of lifeguards, beach patrol flags, and signs.
