NWS Advisories in Effect; Rainy Weather Expected Over the Next Few Days

The National Weather Service (NWS) Weather Forecast Office Guam has the following advisories in effect:

A flash flood watch is in effect for Guam, Rota, Tinian, and Saipan, through Tuesday afternoon. A monsoonal pattern will bring periods of heavy showers to the Marianas through Tuesday. Rainfall of 2 to 4 inches is possible with locally higher amounts. The ground is wet in some locations and additional rainfall will enhance the flash flood threat.

Rainfall of this magnitude will produce flash flooding, especially in flood-prone, low-lying and urban areas near rivers and streams. The community is advised to monitor the latest forecasts and be alert for possible flash flood warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop.

The following are basic flood safety tips to keep in mind:

Now is a good time to clear drainage areas and un-block clogged storm drains in your area to minimize the chance of flooding.
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. Do not leave the car and enter moving water.
Avoid camping or parking along streams, rivers, and creeks during heavy rainfall. These areas can flood quickly and with little warning.

A thunderstorm advisory is in effect for the Guam International Airport until 8:30 p.m. this evening. Thunderstorms are possible within 20 nautical miles of the airport. Be alert and take precautions as required.

NWS is closely monitoring a tropical depression that has formed north of Yap, about 445 miles west of Guam. It will maintain the monsoonal flow over Yap and Palau for several more days. A wet monsoonal pattern is still expected across the region the next few days. While there is no direct threat to the Marianas from the tropical depression, showery weather and breezy winds tonight through the next couple days are expected.

NWS advises the region will see a lot of activity at least through the next two weeks. The community is advised to stay up-to-date with the latest forecasts and any advisories through the following links:

X Flooding is a temporary overflowing of water onto land that is normally dry. Flooding may happen with only a few inches of water, or it may cover a house to the rooftop. There are many possible causes of floods including heavy rain, coastal storms and storm surge, waterway overflow from being blocked with debris, or overflow of levees, dams, or waste water systems. Flooding can occur slowly over many days or happen very quickly with little or no warning, called flash floods.
