.STORM INFORMATION... At 1 PM ChST, the center of Super Typhoon Bavi (09W) was located near latitude 13.1N, longitude 148.5E. This was about 250 miles east of Guam. Storm motion was west-northwest, 285 degrees, at 8 mph. Storm intensity was 155 mph.

.SITUATION OVERVIEW... A Typhoon Warning remains in effect for the Marianas as Super Typhoon Bavi (09W) continues its approach. Bavi is expected to make passage through the southern Marianas beginning Monday morning at high-end Category 4 or Category 5 strength. It is expected to continue toward the west-northwest and gradually increase in forward speed through Monday. The onset of tropical storm force conditions is currently expected this evening. The latest forecast track still maintains passage somewhere near or to the north of Rota Island, but there is time for the track to shift north or south. All islands will experience impacts. At minimum, damaging tropical storm force conditions are expected, but damage will be catastrophic near the center of Super Typhoon Bavi, with maximum sustained winds forecast at 160 mph at time of passage Monday morning. Significant flooding from torrential rains, and coastal inundation are expected. Surf will become extremely dangerous ahead of Bavi's approach, potentially reaching 35 feet Monday. Significant coastal inundation and erosion are expected, with storm surge reaching 6 to 9 feet near the storm center with 10 to 15 feet of wind- and wave-driven runup.

For the islands closest to passage of Super Typhoon Bavi, the onset of typhoon conditions is expected Monday morning just ahead of Bavi's center, continuing through Monday afternoon. Destructive typhoon conditions may be expected for 8 to 10 hours close to the center's passage, depending on forward speed.
