The National Weather Service office in Tiyan has their eye on a weak circulation that is currently 300 miles southwest of Guam.
This area is unlikely to form into a significant system but will bring scattered showers to Guam Sunday and Monday.
In the meantime forecasters have issued an urban and small stream flood advisory for Guam, in effect until 2:30 p.m.
A Flood Advisory means river or stream flows are elevated, or ponding of water in urban or other areas is occurring or is imminent.
Up to one inch of rain has already fallen and heavy rain moving into Guam will cause urban and small stream flooding.
Residents and visitors are advised to take the following precautionary actions:
· 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) advise residents and visitors to practice extreme caution while traveling in rainy conditions, driving below the speed limit and allowing enough braking distance between vehicles.
