... Winds...
gusts to 60 mph have already been measured near the Kohala
Mountains upslope from Kawaihae. Wind gusts in excess of 55 mph
have also been reported near Kamuela... Kawaihae... Waikoloa... and
South Point. In some areas... sustained winds of 35 to 50 mph with
gusts to 70 mph will occur through tonight. The areas most likely
to have the strongest winds will be over mountainous
terrain... through passes... and where winds blow downslope. Winds
are forecast to fall below 39 mph for all areas by early Thursday
morning.

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
structures.

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

... Storm surge and storm tide...
large and damaging surf 15 to 25 feet will continue along east
facing shores late this afternoon through tonight. 12 to 15 foot
surf is being reported along the hamakua coast and 18 to 25 foot
surf is being reported in Pahoa and Kapoho.

Wave runup may cause significant coastal flooding and damage to
coastal properties and infrastructure... including roadways. Of
particular concern is the the Kalapana-Kapoho Highway between
Pohoiki and Kapoho. Impassable roads due to high water have been
reported in the Kapoho subdivision. 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 for the entire area. Outer
rainbands from Madeline have moved onshore and additional heavy
rainfall will continue today and tonight. 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.

off their gas... only a trained Hawaii gas employee can turn it
back on. Never attempt to turn the gas back on yourself.

... Probability of tropical storm/hurricane conditions...
the chance for hurricane conditions at South Point is 4 percent.

percent... at Kailua-Kona is 32 percent... and at South Point is 93
percent. Except for South Point... these values are significantly
lower compared to the last advisory.

based on the latest forecast track... tropical storm force winds
over 39 mph... 34 knots... are expected to begin spreading over the
area later 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... winds will be as high as 50 to 75 mph with gusts to 100
mph.

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
structures.

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

... 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 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.
