What to do: Make the final preparations to protect life and property. Rush to completion the hardening of your home or business by closing shutters and bracing garage doors. If evacuating, leave as soon as possible. Guard against being stuck out on roadways when dangerous winds and heavy rains arrive. Again, do not stay in a metal roof or container home. Remember, pets are not allowed in most official shelters, so check ahead with your intended shelter. If staying in a home, turn the refrigerator to maximum cold and keep it closed. Turn off propane tanks and unplug small appliances. Fill the bathtub with water in case the tap water becomes unavailable after the storm. This is for cleaning and flushing purposes. Do not drink it.

* WHAT...Flooding caused by excessive rainfall continues to be possible. * WHERE...Guam, Rota, Saipan and Tinian. * WHEN...Through Sunday afternoon. * IMPACTS...Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Flooding may occur in poor drainage and urban areas. Storm drains and ditches may become clogged with debris. Extensive street flooding and flooding of creeks and rivers are possible. * ADDITIONAL DETAILS... - Tropical Storm Champi (29W) will drop copious amounts of rain over Sunday and Monday...although an unexpected southward shift in track will reduce these somewhat. Tinian and Saipan will see around 4 to 6 inches, Rota could receive 10 to 15 inches, and Guam might get 12 to 20 inches. - http://www.weather.gov/safety/flood

* WHAT...For the Coastal Flood Warning, significant coastal flooding expected. For the High Surf Warning, dangerously large breaking waves up to 35 feet for Guam, 20 to 25 feet for Rota, and 15 to 20 feet for Tinian and Saipan. * WHERE...Guam, Rota, Tinian and Saipan. * WHEN...From 5 PM this afternoon to 4 AM ChST Monday. * IMPACTS...Numerous roads may be closed. Low-lying property including homes, businesses, and some critical infrastructure will be inundated. Shoreline erosion will occur. Breaking waves can sweep people off their feet, and into dangerous seas. Life- threatening swimming conditions and significant beach erosion can be expected. Coastal inundation of 5 to 7 feet for Guam, 2 to 4 feet for Rota and 1 to 3 feet for Tinian and Saipan is possible along with coastal flooding and beach erosion. * ADDITIONAL DETAILS...Surf is expected to rise rapidly to dangerous levels tonight. Coastal impacts to the western coast of Guam and Rota are highly dependent on the final track of Champi; passage south of Guam would be reduced impacts whereas passage over Guam would result in larger coastal inundation.

What to do: Everyone should remain out of the water due to life-threatening surf conditions. Stay well away from the coast.

ESFGUM This Hydrologic Outlook is for Guam, Rota, Tinian, and Saipan. Invest 96W is still a broad, disorganized disturbance located about 300 miles north of Kosrae. Ensemble model guidance continues to show a passage anywhere between south of Guam to north of Saipan as a tropical storm or typhoon. Uncertainty is still high regarding timing, location, and intensity, but the potential for locally heavy rainfall and flooding continues to increase approaching this weekend. This is expected to produce 5 to 8 inches of rainfall between Saturday and Monday, with localized amounts up to 12 inches possible. As showers are likely to persist, consistent rainfall is likely to saturate the soils enough to increase chance for mudslides. Residents on these islands need to closely monitor this developing situation as flood watches, advisories and flash flood warnings could be issued later this weekend. If living near streams and rivers, prepare to move items away from stream and river banks. Make sure storm drains nearby are not clogged, especially If living at low-lying areas.
