Wind Advisory in Effect through Tuesday; Hazardous Surf and Seas Remain

The National Weather Service (NWS) Guam Weather Forecast Office continues to monitor a developing tropical system, known as Invest 93W, located northwest of Saipan. As part of the tropical system, a southwesterly monsoon flow is strengthening. Showers will continue to increase in coverage from south to north across the Marianas, with locally heavy showers and a few thunderstorms possible.

A wind advisory is in effect for Guam, Rota, Tinian, and Saipan through Tuesday afternoon. Sustained winds of 30 mph with gusts to 40 mph, are expected mainly in the afternoon hours and for locations in higher terrain. These stronger winds may also occur frequently with heavier showers and thunderstorms.

With strong winds anticipated in the coming days, secure loose objects, canopies and tarps. Rainfall amounts of 4 to 8 inches, with locally higher amounts are possible through Wednesday afternoon.

Those living in flood-prone areas should take action; clear drainage areas and unblock storm drains to minimize flooding. Residents and visitors are advised to take the following precautionary actions:

Stay up to date with the latest information;
Be prepared to take action if warranted;
Remain out of hazardous surf and seas for south and west facing reefs;
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, and rivers, during heavy rainfall. These areas can flood quickly and with little warning.

A high surf advisory remains in effect for Guam, Rota, Tinian, and Saipan until 6 a.m. Saturday. Large breaking waves of 7 to 9 feet for south facing reefs are expected. Inexperienced swimmers should remain out of the water due to dangerous swimming and surf conditions.

A high risk of rip currents remains in effect for Guam, Rota, Tinian, and Saipan through late Friday night. Rip currents can sweep even the best swimmers away from the shore into deeper water. Remain out of the water due to dangerous conditions. 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 remains in effect for the coastal waters of Guam and Rota until 6 a.m. Saturday. Southwest winds of 15 to 25 knots, with frequent gusts up to 30 knots are likely through Tuesday afternoon. Seas of 7 to 10 feet will continue this week. Conditions will be hazardous to small craft. Inexperienced mariners, especially those operating smaller vessels, should avoid navigating in hazardous conditions.

The Offices of Guam Homeland Security and Civil Defense (GHS/OCD) remind the community to practice caution while traveling in gusty winds and 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.
