The National Weather Service (NWS), Guam Weather Forecast Office has issued an urban and small stream flood advisory for Guam until 1:15 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 due to thunderstorms will cause urban and small stream flooding in the advisory area. Up to one inch of rain has already fallen and additional rainfall of up to two inches is expected, resulting in flooding in poor drainage areas.
Residents and visitors are advised to take the following precautionary actions:
* Clear drainage areas and un-block clogged storm drains in your area to minimize the chance of flooding.
* Turn Around, Don’t Drown. Avoid walking or driving through floodwaters. 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.
* Avoid camping, parking, or hiking along streams, rivers, and creeks during heavy rainfall. These areas can flood quickly and with little warning.
