Urban and Small Stream Flood Advisory in Effect; Practice Caution in Heavy Rain

The National Weather Service (NWS) Guam Weather Forecast Office issued a short term forecast for Guam. Through 1:30 p.m., heavy showers have developed over Guam and Guam coastal waters. Expect occasional lightning and rainfall up to two inches with these heavy downpours. More showers and thunderstorms are expected through the day.
If driving, be alert for sudden changes in visibility and for ponding of water on the road. Boaters can expect visibility down to half a mile in heavy showers and are advised to stay below deck if lightning is seen or thunder is heard.
An urban and small stream flood advisory is in effect for Guam until 1:30 p.m. A Flood Advisory means river or stream flows are elevated, or ponding of water in urban or other areas is occurring or is imminent. Heavy rain will cause urban and small stream flooding on Guam. Areas of concern include Tamuning, Tumon, Harmon and surrounding areas. Rainfall of one inch has likely fallen with flooding likely in poor drainage areas. Some locations that will experience flooding include Dededo, Tamuning and Tumon.
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;
· Visit https://www.ready.gov/floods to learn more.
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.
