The National Weather Service (NWS), Weather Forecast Office Guam has upgraded its flood advisory to a flash flood warning, in effect for Guam until 3:30 p.m. this afternoon, which means flooding is occurring or imminent.

Heavy showers and thunderstorms are producing heavy rain across Guam. NWS rain gauges indicated heavy rain falling across southern Guam, especially in the villages of Agat, Umatac, Merizo, Inarajan, and surrounding areas.

Rain was falling at a rate of 2 to 4 inches per hour. Flash flooding is occurring in drainages, streams, rivers, roads, properties, and other low-lying areas. Public road closures are possible in some areas. Landslides are also possible in steep terrain.

Residents and visitors are advised to take the following precautionary actions:

· Residents living along streams and creeks should take immediate action to protect life and property. Move to higher ground.

· If there is a flooding emergency, contact 911.

· Stay away from storm drains, culverts, creeks, and streams.

· Water levels can rise rapidly and sweep people away.

· Turn Around, Don’t Drown. Avoid walking or driving though 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 flood waters 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.

· Do not camp, park, or hike along streams, rivers, and creeks during heavy rainfall. These areas can flood quickly and with little warning.
