... Precautionary/preparedness actions...
precautionary/preparedness actions...

Cover and secure windows and brace garage doors. Loose objects
such as lawn furniture... garbage cans... and other items should be
secured or stored indoors.

If evacuating... leave as soon as possible. Do not get stuck on
the roads when the dangerous winds and heavy rains arrive.

If staying in a home... turn the refrigerator to maximum cold and
keep it closed. Unplug small appliances and sensitive electronics.
Fill the bathtub with water for cleaning and Flushing in case the
tap water becomes unavailable.

Hawaii gas advises that propane tank and Cylinder customers
should not shut off their gas supply unless evacuating their
premises due to disaster related conditions. If a customer shuts
off their gas... only a trained Hawaii gas employee can turn it
back on. Never attempt to turn the gas back on yourself.

Stay out of streams... rivers... and low-lying flood prone areas.

... Probability of tropical storm/hurricane conditions...
the chance for hurricane conditions at Hilo is 5 percent...
Kailua-Kona is 3 percent... and South Point is 25 percent.
Also... the chance for tropical storm conditions at Hilo is 85
percent... at Kailua-Kona is 74 percent... and at South Point is 95
percent. These values are slightly higher compared to the last
advisory. The onset of tropical storm conditions could start as
early as late this morning. The onset of hurricane conditions
could start as early as this evening.

... Winds...
based on the latest forecast track... tropical storm force winds
over 39 mph... 34 knots... are expected to begin spreading over the
area late this morning followed by the arrival of hurricane force
winds of 74 mph... 64 knots... or higher this evening. Hurricane
force winds could last for a few hours in some areas. In some
areas... winds will be as high as 50 to 75 mph with gusts to 100

Gusts will be strongest over mountainous terrain... through
passes... and where winds blow downslope. Winds affecting the
upper floors of high rise buildings will be significantly
stronger than those near ground level.

Winds this strong would be very dangerous and airborne debris
could produce widespread damage. Any loose outdoor items would
become projectiles... causing possible injury. Other possible wind
damage would include... downed large trees and power lines... and
significant roof and structure damage... especially to weaker

Extensive damage to power lines and poles could result in
widespread power outages that could last from several days to

... Storm surge and storm tide...
large and damaging surf is expected along east facing shores.
Surf will build today... and peak at 15 to 25 feet late this
afternoon through tonight. Depending on the exact track of
Madeline... storm surge will range from 1 to 3 feet. The
combination of storm surge and wave runup may cause significant
coastal flooding and damage to coastal properties and
infrastructure... including roadways. Powerful longshore and rip
currents will be present at most beaches. Large breaking waves and
strong currents may impact Harbor entrances and channels causing
challenging boat handling.

... Inland flooding...
a Flash Flood Watch is in effect. Deep tropical moisture
associated with the Madeline will begin to impact The Big Island
this morning... bringing the threat of heavy rainfall and flooding
through late Thursday. Total rain accumulations of 5 to 10 inches
are possible... with isolated maximum amounts near 15
inches... especially over windward portions of The Big Island. This
rainfall may lead to dangerous flash floods and mudslides. Refer
to the watch for more details.
