.STORM INFORMATION...
At 8 AM ChST, the center of Super Typhoon Bavi (09W) was located
near latitude 12.9N, longitude 149.2E. This was about 300 miles
east of Guam. Storm motion was west, 280 degrees, at 7 mph. Storm
Intensity was 155 mph.
.SITUATION OVERVIEW...
A Typhoon Warning remains in effect for the Marianas. Super
Typhoon Bavi (09W) 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 make a turn toward the
west-northwest and gradually increase in forward speed through
Monday. The onset of tropical storm force conditions is currently
expected late this afternoon or 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.
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 inundation
heights reaching up to 12 feet especially near the storm center.
For the islands closest to passage of Super Typhoon Bavi, the
onset of typhoon conditions is expected early Monday morning just
ahead of Bavi's center, continuing through Monday afternoon. The
latest forecast from the Joint Typhoon Warning Center (JTWC)
suggests that destructive typhoon conditions may be expected for 8
to 10 hours close to the center's passage depending on forward
speed.
Instruction:
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.
Preparations should be completed today for damaging winds which
could start Monday morning.
Stay calm and keep informed. Comply with any evacuation orders that
are issued for your area. Seek sturdy shelter, in a cave if
necessary.
Items to bring to a shelter include a first aid kit, medicines
and prescriptions, baby food and diapers, games and books,
toiletries, a battery powered radio, a cell phone, flashlights
with extra batteries, a blanket or sleeping bag for each person,
personal identification, copies of key papers such as insurance
policies, available cash and credit cards. Remember, pets are not
allowed in most public shelters, so check ahead with your
intended shelter.
Regarding your home or business, cover all windows and doors with
shutters or plywood. Move patio furniture and other loose objects
indoors. Brace all exterior doors, including garage doors. Do
this as early as possible.
