A weak circulation south of Guam is expected to move into our area through the week slowly intensifying. The National Weather Service Guam is monitoring the circulation, which is expected to bring scattered showers with brief periods of numerous showers through the week. The heaviest rainfall is possible Thursday and Friday.

As the system moves well west of the Marianas, the monsoon trough will drift further north keeping the Marianas in an unsettled wet pattern through the end of the week, according to the Office of Homeland Security and Civil Defense. Also, weather conditions can quickly change in this current weather pattern.

How to Prepare 

Localized flooding will be possible in low-lying and poor drainage areas. Residents and visitors are advised to take precautionary actions now before heavy rains occur:

• 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

• Be prepared to move immediately to higher ground if there is a chance of flash flooding.

• 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.
