Flash Flood Watch, Areal Flood Advisory

Statement as of 3:00 PM HST on February 27, 2017

Expires 10:15 PM EST on February 27, 2017


... Flash Flood Watch remains in effect through Wednesday
afternoon...

The Flash Flood Watch continues for

* Kahoolawe, Kauai, Lanai, Maui, Molokai, Niihau, Oahu and The
Big Island.

* Through Wednesday afternoon

* increasingly moist and unstable air will overspread the islands
tonight and Tuesday. Spotty intense showers, mainly windward and
Mauka tonight, could become more widespread by Tuesday. A
strong upper level disturbance will cause a surface trough or
low to develop near the islands over the next couple of days,
enhancing the potential for heavy downpours and thunderstorms
that could lead to flash flooding. Conditions should gradually
improve later in the day on Wednesday.

* Some streams and normally dry gulches are expected to run high
and could quickly overflow their banks. Intense rainfall in
poor drainage and urban areas could also lead to flash
flooding.

Precautionary/preparedness actions...

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

Keep tuned to later forecasts and be prepared to take action
should flash flood warnings be issued. Consider postponing camping
or hiking trips until the weather improves.

225 PM HST Mon Feb 27 2017

The National Weather Service in Honolulu has issued a

* flood advisory for...
the island of Maui in Maui County

* until 515 PM HST

* at 225 PM HST, radar showed thunderstorms with heavy rain located
upslope from Kaupo and Kipahulu. Rain was falling at a rate of 1
to 2 inches per hour.

* Locations in the advisory include but are not limited to...
Kaupo, Kipahulu, Nahiku, Keanae, Hana, Wailua, Hamoa and Haleakala
National Park.

Precautionary/preparedness actions...

Stay away from streams, drainage ditches and low lying areas prone to
flooding.

Rainfall and runoff will also cause hazardous driving conditions due
to ponding, reduced visibility and poor braking action.

Do not cross fast flowing or rising water in your vehicle, or on
foot. Turn around, don't drown.

A Flash Flood Watch is also in effect. Pay attention in case flash
flood warnings are needed.


This advisory may need to be extended beyond 515 PM HST if heavy rain
