Flood Watch Remains in Effect; Hazardous Surf and Seas Expected

The National Weather Service (NWS) Guam Weather Forecast Office advised a flood watch remains in effect for Guam, Rota, Tinian, and Saipan from through Monday afternoon. Flooding caused by excessive rainfall is possible.

Heavy showers and thunderstorms associated with a tropical disturbance are expected. Rainfall amounts between 3 and 5 inches, with locally heavier amounts in excess of 8 inches, is possible through late Monday afternoon. Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations.

Residents and visitors, especially those living in flood-prone areas, are advised to take the following precautionary actions:

Clear drainage areas and unblock clogged storm drains in your area;
Stay up to date with the latest information;
If driving, be alert for low visibilities and slippery roads in heavy rain;
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, rivers, and creeks during heavy rainfall. These areas can flood quickly and with little warning.

Inexperienced swimmers should remain out of the water due to dangerous surf conditions.

A high surf advisory is in effect for Guam, Rota, Tinian, and Saipan from 6 a.m. Monday until 6 a.m. Tuesday. Large breaking waves of 7 to 9 feet are expected in the surf zone. Dangerous swimming and surfing conditions and localized beach erosion are expected.

A high risk of rip currents is in effect for Guam, Rota, Tinian, and Saipan from Monday morning through late Monday night. Rip currents can sweep even the best swimmers away from the shore into deeper water. If caught in a rip current, do not swim against the current. Swim in a direction following the shoreline, face the shore and call or wave for help.

A small craft advisory is in effect for the coastal waters of Guam, Rota, Tinian, and Saipan from 6 p.m. this evening until 6 a.m. Tuesday. East winds of 15 to 25 knots, with occasional gusts up to 35 knots, and seas of 8 to 10 feet are expected. Inexperienced mariners, especially those operating smaller vessels, should avoid boating in hazardous conditions.

The Offices of Guam Homeland Security and Civil Defense (GHS/OCD) remind the community to practice caution while traveling in heavy rain, driving below the speed limit and allowing enough braking distance between vehicles.

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.
