Flood Advisory in Effect; Practice Caution in Heavy Rain

The National Weather Service (NWS) Guam Weather Forecast Office issued a flood advisory, in effect for southern Guam until 5:30 p.m. this afternoon. Urban and small stream flooding caused by excessive rainfall is expected. Between 0.8 and 1.2 inches of rain has fallen. Additional rainfall amounts of 1 to 3 inches are possible over the area.

Some locations that will experience flooding include Yona, Talofofo, Inarajan, Merizo, Santa Rita, and Umatac.

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

  • If driving, be alert for low visibilities and slippery roads in heavy rain;
  • Slow down where water is ponding on the road;
  • 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;
  • Do not camp, park, or hike along streams and rivers. These areas can flood quickly and with little warning.
  • When thunder roars, get indoors.

 The Offices of Guam Homeland Security and Civil Defense (GHS/OCD) remind the community to practice caution while traveling in rainy conditions, driving below the speed limit and allowing enough braking distance between vehicles.
