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 Guam until 11:30 a.m. Flooding caused by excessive rainfall is expected. Between 0.5 and 1.5 inches of rain has already fallen. Additional rainfall amounts of 0.75 to 1.5 inches are expected, resulting in minor flooding.

Some locations that will experience flooding include Dededo, Tamuning, Yigo, Mangilao, Chalan Pago-Ordot, Barrigada, Yona, Hagatna Heights, Andersen AFB, Mongmong-Toto-Maite, Sinajana, Asan, Piti, and Santa Rita.

Residents and visitors 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, rivers, and creeks during heavy rainfall. These areas can flood quickly and with little warning.

A thunderstorm advisory is in effect for the Guam International Airport until 11:15 a.m. Thunderstorms are possible or occurring within 20 nautical miles of the airport. If lightning is seen, or thunder is heard, seek shelter indoors.

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