The National Weather Service (NWS) Guam Weather Forecast Office continues to monitor an approaching tropical disturbance, expected to bring the potential for heavy rainfall in the region. The system remains in the formative stages and there remains uncertainty on the exact track and intensity as it approaches the Marianas.

A flash flood watch will be in effect for Guam, Rota, Tinian, and Saipan, from Thursday morning through Friday afternoon. Heavy showers and thunderstorms associated with the tropical disturbance will affect the islands in the next 36 to 48 hours.

Rainfall of 3 to 5 inches with locally heavier amounts are possible for Tinian and Saipan, with 2 to 4 inches possible for Rota, and 1 to 3 inches for Guam.

As of this afternoon, the circulation was centered north of Chuuk, near 11 degrees north latitude and 150 degrees east longitude, roughly 400 miles east-southeast of Guam, moving west-northwest at 13 mph. It is expected to strengthen as it heads near or through the Marianas by the end of this week.

Residents and visitors are advised to take the following precautionary actions through Friday:

· Avoid driving on flooded roads;

· 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;

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

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