This product covers the Hawaiian islands



- All watches and warnings have been canceled

- None

- About 110 miles southwest of Honolulu
- 20.1N 159.0W
- Storm Intensity 40 mph
- Movement West-southwest or 255 degrees at 20 mph


The center of Tropical Storm Olivia was located near latitude 20.1 North,
longitude 159.0 West, which is about 110 miles southwest of Honolulu and is
moving away from the state to the west southwest at 20 mph (31 km/h).
This motion is expected to continue through tomorrow with a slight decrease in
forward speed, followed by a turn toward the west on Friday.

The atmosphere will remain very moist though Thursday as a low
aloft approaches from the northeast. The low aloft will make the
atmosphere unstable, so the threat of heavy rain will persist
after the winds from Olivia have subsided. The heaviest rain will
likely shift to Kauai on Thursday. A Flood Watch remains in effect
for all islands through Thursday night.


Additional impacts from flooding rain are still a concern across the state
of Hawaii. Remain well guarded against life-threatening flood waters having
further impacts of devastating potential. A Flash Flood Watch remains in
effect through Thursday night.


Do not enter evacuated areas until officials have given the all clear to return.


Remain safely sheltered until conditions improve. When going outside
be sure to stay away from downed power lines, hazardous debris and
flooded areas.

If your home or shelter was damaged, be alert to the smell of gas
leaks and be cautious around electrical wiring, broken glass, jagged
metal and wood, and protruding nails and screws.

Check to see if everyone in your group is OK. Administer first aid to
those who are injured. If possible, call 9 1 1 for any serious
injuries. Remember, it may be difficult for emergency responders to
arrive quickly.

Check in with your emergency points of contact. Let them know your
location and status. Keep conversations short and to the point. Do
not tie up communications systems.

Check on your neighbors. If necessary, help them connect with their
points of contact.

Do not attempt to return to evacuated areas until local authorities
have inspected roads and bridges and have given the all clear.
Hazards like downed power lines and trees, washed out roads,
continued flooding in low lying areas and non-functioning traffic
lights make travel difficult.

Allow extra time for emergency vehicles to reach you as they navigate
road hazards.

Do not attempt to return to evacuated areas until local authorities
give the all clear. Allow time for officials to inspect bridges and
overpasses and to mark washed-out roads.

When entering areas that have been heavily damaged, bring along a
GPS-enabled device to help with street navigation. Do not drive on
roads that have been marked closed.

Do not go sightseeing within impacted communities. Sightseers
interfere with the emergency work of first responders.

When inspecting damage, use flashlights rather than candles or flamed
lanterns. Be aware of sparks that can ignite natural gas or other
leaking flammables.

Do not go up on your roof until the weather conditions are safe.
Ladders can be slippery in the rain and unexpected wind gusts can
blow you off the roof.

When clearing out fallen trees, be careful with chainsaws and axes.
Always wear protective gear and keep others at a safe distance.
Leaning trees and those which have fallen on roofs or power lines can
be especially dangerous. If you are not in good health or unsure
about what you are doing, have someone with tree cutting experience
do the job. Never cut trees without a partner.

Problems with sewer backups can further contaminate standing flood
waters. Keep children away from flood waters. Also, listen for boil
water alerts as tap water may have become non-potable.

Be alert for any lingering wind gusts which could take down weakened
trees and/or power lines, collapse damaged structures, or cause
flying debris.

Be alert for potential flooding from rising rivers and streams which
may have yet to crest. Remain informed of the latest river forecasts
and heed any flood watches and warnings.

Be alert for flooded roads which could be compromised or littered
with debris. Avoid travel until water levels subside and roads have
been cleared. Do not drive through places where flood waters cover
the road. Turn around, don't drown!
