The National Weather Service (NWS), Guam Weather Forecast Office issued a flash flood warning for Guam until 10 a.m.
 
Thunderstorms are producing heavy rain across the area. Up to an inch of rain has already fallen. Additional two to four inches is possible. Flash flooding is expected to begin.
 
The worst flooding will be in Merizo. Other locations that will be impacted include Polaris Point, Dededo, Tamuning, Mangilao, Ordot Chalan Pago, Yigo, Barrigada, Yona, Agana Heights, Andersen AFB, Talofofo, Sinajana, Mongmong-Toto-Maite, Inarajan, Asan, Piti, Santa Rita, Hagatna, and Umatac.  
 
Residents and visitors are advised to take precautionary actions:
· Move to higher ground.
· Stay away from storm drains, culverts, creeks, and streams.
· Water levels can rise rapidly and sweep people away.
· 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
· If there is a chance of flash flooding, move immediately to higher ground.
· 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.

Surf will remain hazardous at 8 to 11 feet along south facing reefs and 11 to 14 feet along west facing reefs. Avoid venturing out along south and west facing reefs and beaches. Large breaking waves can knock people down and cause serious injuries. Strong rip currents will be life threatening.
 
small craft advisory remains in effect for Guam, Rota, Tinian, and Saipan coastal waters until 6 a.m. Thursday, meaning wind speeds and heavy seas are expected to produce wave conditions hazardous to small craft. Southwest winds of 19 to 29 mph with occasional gusts to 39 mph are expected. Seas of 10 to 12 feet will continue through Thursday. Inexperienced mariners, especially those operating smaller vessels, should avoid sailing in these conditions.
