Flood Advisory in Effect; Drive with Caution through this Morning

The National Weather Service (NWS) Guam Weather Forecast Office advised a trade-wind trough and a monsoon trough are converging over Guam and Rota this morning. The two features will interact bringing heavy rain.

flood advisory is in effect until 11:15 a.m. this morning for Guam. Heavy rain due to thunderstorms will cause urban and small stream flooding. Between 0.2 and 0.6 inches of rain have already fallen. Additional rainfall amounts of 1 to 4 inches are expected.

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

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

  • Be aware of your surroundings and do not drive on flooded roads.
  • If driving, be alert for low visibilities 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.

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