Heavy Rains Possible this Weekend into Early Next Week; Take Flood Preparedness Actions Now

The National Weather Service (NWS) - Guam Weather Forecast Office issued a hydrologic forecast for the Marianas as a flood potential outlook.

 

A developing tropical disturbance and its associated monsoon trough will gradually drift west-northwestward over the Marianas Islands for the weekend, generating locally heavy downpours beginning as early as Friday evening through Monday night.

 

NWS advised current models show rainfall amounts of up to 10 inches over the Marianas, expected by Monday evening. If the circulation makes a slight shift to the east, it could bring rainfall amounts in excess of 20 inches to the island.

 

Although NWS advises they do not expect to see significant organization of the system until it is well west of the Marianas, the rainfall amounts will increase. Now is the time to take flood preparedness actions.

 

Those living in areas prone to flooding should be prepared to take action:

·         Now is the time to clear drainage areas and un-block clogged storm drains in your area to minimize the chance of flooding

·         Residents living near rivers and streams need to review plans for protecting properties

·         Once heavy rains occur, avoid walking or driving through flood waters

o    Just 6 inches of moving water can knock you down, and 2 feet of water can sweep your vehicle away

o    If there is a chance of flash flooding, move immediately to higher ground

o    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.

o    Avoid camping, parking, or hiking along streams, rivers, and creeks during heavy rainfall. These areas can flood quickly and with little warning.
