Bavi is expected to gradually weaken this week and threaten northern Taiwan and Japan's Ryukyu Islands as a Category 3 storm on Friday.

Residents of the U.S. territory of Guam are bracing for potentially catastrophic conditions from Super Typhoon Bavi, which may hit the island as a Category 5 storm.

Bavi is expected to pass through the U.S. Northern Mariana Islands near Tinian and Saipan islands Sunday afternoon (U.S. EDT) as a Cat 5, potentially causing catastrophic damage.
