STORM INFORMATION: At 200 PM ChST, the center of Tropical Storm Champi (29W) was located near latitude 11.4N and longitude 153.3E, about 300 miles north- northeast of Chuuk and about 590 miles east-southeast of Guam. Storm motion was west, 265 degrees, at 24 mph. Storm intensity was 50 mph. Champi will continue on this trajectory and slow down as it continues barreling toward the Marianas. This general forecast track will take Champi close to, or over, Guam Sunday morning. Champi is forecast to continue intensifying over the next few days, likely becoming a typhoon by Saturday.
-
SITUATION OVERVIEW: Mostly benign conditions are expected across the Marianas tonight, followed by a steady increase in showers and winds Friday afternoon, and then deteriorating significantly coming into Saturday night as Tropical Storm Champi continues to move in from the east-southeast. Champi is expected to go through a period of rapid intensification over the next 24 hours, becoming a typhoon by Saturday and strengthening further thereafter. 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!

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.
-
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 is approaching the Marianas and will bring torrential rain Saturday night and Sunday at least. Total rainfall accumulations of 12 to 20 inches are possible for Guam, 10 to 18 inches for Rota and 8 to 12 inches for Tinian and Saipan. This could cause flooding problems in poor drainage and flood prone areas.
