The National Weather Service (NWS) Guam Weather Forecast Office has issued a flash flood warning for Guam, in effect until noon.

Flash flooding is ongoing or expected to begin shortly. Thunderstorms are producing heavy rain across the area. Between 0.4 and 1 inch of rain has already fallen. The expected rainfall rate is around 1.5 inch per 1 hour.

Expected impacts include flash flooding of small creeks and streams, urban areas, highways, streets and underpasses as well as other poor drainage and low-lying areas.

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

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

· Report road hazards or flooding to local emergency services.

· 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 floodwaters. Just 6 inches of moving water can knock you down, and 2 feet of water can sweep your vehicle away;

· Avoid camping, parking, or hiking along streams, rivers, and creeks during heavy rainfall. These areas can flood quickly and with little warning;
