Officials are urging residents who live in flood-prone areas to move to higher ground as the National Weather Service, Tiyan Guam office has upgraded a flash flood advisory to a warning.
"Heavy showers and isolated thunderstorms are producing heavy rain across Guam. Over four inches of rain have fallen over parts of the island," a press release from the Guam Homeland Security/Office of Civil Defense stated.
"Flash flooding is occurring. Additional rainfall amounts of two to three inches are possible across Guam."
The warning is expected to remain in effect until 6 p.m. today. A warning means flooding is imminent or occurring officials said.
Residents and visitors are advised to take precautionary actions:
· Residents living along streams and rivers should take immediate precautions 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.
· 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.
· Do not camp, park, or hike along streams, rivers, and creeks during heavy rainfall. These areas can flood quickly and with little warning.
