Heavy Rainfall Possible Saturday Through Monday; Officials Monitor Disturbance Northeast of Pohnpei

The National Weather Service (NWS) Guam Weather Forecast Office issued a hydrologic outlook for Guam. A disturbance northeast of Pohnpei, Invest Area 98W, is anticipated to pass near the Marianas this weekend.

Model consensus indicates the possibility of locally heavy rainfall of 3 to 6 inches across the Marianas. Such rainfall could lead to localized flooding and the potential for flash flooding. Localized flooding will be possible in low-lying and poor drainage areas while flash flooding could also be possible in areas of heaviest rainfall. This developing situation will continue to be monitored closely and a flash flood watch may be issued if conditions warrant.

While there remains some uncertainty on what impacts are expected for the Marianas, to prepare for any circumstance, the community is reminded to take precautionary measures before the weekend:

Stay up to date with the latest information. Watch for flash flood advisories.
Those living in areas prone to flooding should be prepared to take action; clear drainage areas and unblock clogged storm drains in your area to minimize the chance of flooding.
In inclement weather, do not camp, park, or hike 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), with NWS, will continue to monitor all systems in the area and provide updates as needed.

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.
