Press Release: Hydrologic Outlook

The National Weather Service (NWS) Guam Weather Forecast Office forecasts heavy rainfall possible Monday night through Thursday night. A developing tropical disturbance, known as JTWC`s Invest 95W, is currently located just northwest of Pohnpei near 8N158E. Forecast guidance continues to show a gradual organization as it heads towards the Marianas over the next few days.

Model consensus indicates the possibility of locally heavy rainfall of 4 to 8 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.

Guam Homeland Security/Office of Civil Defense reminds residents to monitor local weather forecasts and conditions closely the next few days. Outdoor plans and events should have an alternate plan in place should heavy weather occur.

When thunder roars, get indoors. If you can hear thunder, you are at risk of a lightning strike. Plan ahead and stay informed with the latest news from your local emergency management offices and the National Weather Service.

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.
