The National Weather Service (NWS) Guam Weather Forecast Office advised that a developing monsoon pattern will bring periods of heavy rain across the Marianas over the next few days. Torrential rains could lead to flash flooding in low-lying and poor drainage areas.

A flash flood watch is in effect for Guam, Rota, Tinian, and Saipan through Thursday afternoon. Heavy showers and thunderstorms associated with the monsoon will affect a portion of the Marianas. Rainfall of 3 to 5 inches with locally heavier amounts are possible through Thursday.

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

· Clear drainage areas and unblock clogged storm drains in your area to minimize the chance of flooding.

· 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 extreme caution while traveling in rainy conditions, driving below the speed limit and allowing enough braking distance between vehicles.
