A Tropical Storm Warning and a Typhoon Watch continue for Tinian and Saipan.

-
STORM INFORMATION: At 100 PM ChST, the center of Typhoon Champi (29W) was located near latitude 12.5N and longitude 148.0E. This was about 225 miles east- southeast of Guam. Storm motion was west-northwest, 290 degrees, at 18 mph. Storm intensity has increased to 100 mph, making it a Category 2 typhoon. This general forecast track will take Champi just south of Guam as a Category 3 typhoon as it intensifies further the next few days.
-
SITUATION OVERVIEW: Showers and winds will continue to steadily increase the rest of today, to then deteriorate significantly tonight as newly upgraded Typhoon Champi continues to move in from the east-southeast. Champi is undergoing a period of rapid intensification, strengthening further as the day goes on. The most recent storm tracks continue to indicate Champi passing either south, or over, Guam Sunday morning, which may potentially bring devastating wind conditions to much of Guam during passage. Winds and rain will come in rapidly, with winds becoming dangerous and life threatening very soon after onset. Do not let a false sense of normalcy now dictate your actions tomorrow; prepare NOW!

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: 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.
