The National Weather Service (NWS) Guam Weather Forecast Office advised a wet monsoon pattern is expected for the Marianas before drier weather slowly returns midweek. Although all tropical cyclone development is expected to stay north of the Marianas, excessive rainfall is still expected. Showers are not expected to thin out to normal conditions until after Tuesday.
An urban and small stream flood advisory is in effect for Guam, Rota, Tinian, and Saipan until 4 p.m. Heavy rain will cause urban and small stream flooding. Additional rainfall amounts of 1 to 2 inches are expected over the area resulting in minor flooding.
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;
· Do not camp, park, or hike 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 be alert for possible additional advisories and practice caution while traveling in rainy conditions, driving below the speed limit and allowing enough braking distance between vehicles.
