Flash Flood Warning in Effect for Guam; NWS Advisories in Effect

The following National Weather Service (NWS) Guam Weather Forecast Office advisories remain in effect:
 
high surf advisory and high risk of rip currents remains in effect for Guam, Rota, Tinian, and Saipan until 6 p.m. this evening. Hazardous surf of 8 to 10 feet is expected in the surf zone along north, west, and south facing reefs. Dangerous swimming and surfing conditions and localized beach erosion are expected. Rip currents can sweep even the best swimmers away from shore into deeper water. Remain out of the water due to dangerous surf conditions.
 
small craft advisory remains in effect for the coastal waters of Guam, Rota, Tinian, and Saipan until 6 a.m. Saturday. South winds of 30 knots with gusts to 40 knots, and seas of 9 to 13 feet are expected, creating conditions hazardous to small craft. Inexperienced mariners, especially those operating smaller vessels, should avoid sailing in these conditions.
 
flash flood warning is in effect for Guam until 11:15 a.m. Between 4 and 6 inches of rain have fallen. Additional rainfall amounts of 2 to 3 inches are possible. Flash flooding of small creeks and streams, urban areas, highways, streets and underpasses as well as poor drainage and low-lying areas is occurring. Some locations that will experience flash flooding included Dededo, Tamuning, Yigo, Mangilao, Chalan Pago-Ordot, Barrigada, Yona, Hagatna Heights, Andersen AFB, Talofofo, Mongmong-Toto-Maite, Sinajana, Inarajan, Asan, Merize, Piti, Santa Rita, and Umatac.
 
Route 1, Polaris Point, north and southbound lanes are impassible at this time. Motorists are advised to seek alternate routes. Flooding has also been identified on Route 15, north and southbound lanes, between Spanish Street and up to Andersen, as well as towards Hawaiian Rock.
 
The community is reminded to practice caution on the roadways, driving below the speed limit and allowing enough braking distance between vehicles. Turn Around, Don’t Drown. Immediately move to higher ground if flash flooding occurs. Water levels can rise rapidly and sweep people away. 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. Stay away from storm drains, culverts, creeks, and streams. If floodwaters rise around your car but the water is not moving, abandon the car and move to higher ground. If the water is moving, do not leave the car. Do not camp, park, or hike along streams, rivers, and creeks. These areas can flood quickly and with little warning. 
 
The Offices of Guam Homeland Security and Civil Defense (GHS/OCD), with NWS, will continue to monitor all systems in the area and provide updates as needed.
