More rain is expected this morning. It's enough to prompt the National Weather Service Guam Weather Forecast Office to an urban and small stream flood advisory for Guam until 11:15 a.m.
Heavy rain due to thunderstorms will cause urban and small stream flooding in the advisory area.
Up to 1 inch of rain has already fallen, meteorologists said.
An additional 1 to 3 inches of rainfall is expected over the area, resulting in minor flooding.
Guam Homeland Security/Office of Civil Defense said areas likely to flood 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:
· 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;
· Avoid camping, parking, or hiking along streams, rivers, and creeks during heavy rainfall. 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 extreme caution while traveling in rainy conditions, driving below the speed limit and allowing enough braking distance between vehicles.
