The National Weather Service (NWS) Guam Weather Forecast Office issued a flash flood warning for Guam until 6:15 p.m. A Flash Flood Warning means that flooding is imminent or occurring within the warned area.

Impacts include flooding in drainages, streams, rivers, roads, properties, and other low-lying areas. Flooding of public roadways is possible in some areas. Landslides are possible in steep terrain.

The Offices of Guam Homeland Security and Civil Defense (GHS/OCD) received the following reports of disrupted or impassable roadways. Proceed with extreme caution or seek alternate routes when possible, until a complete assessment is done:

  • Rt. 1, Ilipog by GTA, Upper Tumon

  • Rt. 1 and Rt. 16 by Micronesia Mall, Dededo

  • Rt. 10 by Wendy’s, Barrigada

  • Rt. 1, Polaris Point, Piti

  • Rt. 2, Pagachao, Agat

  • Rt. 1 by Chief Brodie Elementary School, Tamuning

  • Rt. 4, Barcinas St., Merizo

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

· Stay away from streams, rivers, drainage ditches, and culverts, even if they are currently dry;

· Do not cross fast flowing water in your vehicle, or on foot. Turn around, don’t drown;

· If driving, be alert for low visibilities and slippery roads in heavy rain;

· Slow down where water is ponding on the road;

· 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) advise residents and visitors to practice extreme caution while traveling in rainy conditions, driving below the speed limit and allowing enough braking distance between vehicles.
