Watches & Warnings

Flash Flood Watch
Issued: 4:10 AM HST Aug. 30, 2016 – National Weather Service

... Flash Flood Watch remains in effect from Wednesday morning
through late Thursday night...

The Flash Flood Watch continues for

* The Big Island.

* From Wednesday morning through Thursday night.

* Deep moisture associated with Hurricane Madeline is expected to
impact The Big Island beginning Wednesday morning... bringing the
threat of heavy rainfall and flooding through Thursday night.
The greatest initial flood threat will be over the windward
slopes... with the entire island experiencing a flood threat from
later Wednesday through Thursday night. Depending on the exact
track of Madeline... additional islands may need to be added to
the watch later today.


Precautionary/preparedness actions...

A Flash Flood Watch means that conditions may develop that lead
to flash flooding. Flash flooding is very dangerous.

You should monitor later forecasts and be prepared to take action
should flash flood warnings be issued.




Hurricane Warning
Issued: 12:27 PM HST Aug. 30, 2016 – National Weather Service

... Hurricane Warning remains in effect...

... 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.


... Probability of tropical storm/hurricane conditions...
the chance for hurricane conditions at Hilo is 10 percent...
Kailua-Kona is 6 percent... and South Point is 23 percent.
Also... the chance for tropical storm conditions at Hilo is 78
percent... at Kailua-Kona is 68 percent... and at South Point is 90
percent. These values are trending slightly up for the southern
portion of The Big Island. The onset of tropical storm conditions
could start as early as Wednesday morning. The onset of hurricane
conditions could start as early as Wednesday evening.

... Winds...
depending on the exact track of Madeline... some areas could see
winds as high as 60 to 80 mph with stronger gusts possible.

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 this afternoon... and peak at 15 to 25 feet
tonight through Wednesday night. Depending on the exact track of
Madeline... storm surge will range from 1 to 4 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
Wednesday 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.
