11:20 a.m. Tropical Disturbance Developing Southeast of Guam to Track Toward Marianas

The National Weather Service (NWS) Guam Weather Forecast Office continues to monitor Invest Area 90W, a slowly consolidating tropical disturbance, located near 4N and 160E, south-southwest of Pohnpei. 90W is anticipated to move to the west-northwest potentially taking it anywhere from the east of Guam and toward the far northern Marianas, over/near Guam, or to the south of Guam.

Uncertainty Remains on Expected Impact; Stay Updated for Changes

There remains significant uncertainty regarding whether 90W will head directly toward the Marianas or take a track more to the northeast or south of Guam. For now, the Marianas has the potential for increasing showers, thunderstorms, and gusty winds, developing over the weekend and into early next week. This forecast will be closely monitored and may be updated as it becomes clearer how 90W will develop in eastern Micronesia.

Early Preparedness

In preparation for any possibility, residents and visitors are advised to take the following precautionary actions:

Those living in flood-prone areas should prepare to take action such as clearing drainage areas and unblocking storm drains to minimize the potential for flooding;
Stay up to date with the latest information;

Clear loose debris around your yard and prepare to secure any items, such as tents and canopies, that could become airborne with heavy winds, before inclement weather arrives;

Prepare to secure construction sites and loose items on sites.
Secure or be prepared to take down signs such as campaign signs

Once inclement weather arrives:

If driving in heavy rain, be alert for low visibilities and slippery roads;
Slow down where water is ponding on the road;
Turn Around, Don’t Drown. 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;
Do not camp, park, or hike along streams and rivers. These areas can flood quickly and with little warning.
When thunder roars, get indoors. Tents, canopies and tarps are not safe shelter during thunderstorms.

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.
