HIRSC - Weather Team Update for East Hawaii as of 6:00 pm Wednesday evening:

The National Weather Service in Honolulu has extended the

* Flood advisory for...

The island of Hawaii in Hawaii County

* Until 900 PM HST.

* At 550 PM HST, radar showed showers continuing to stream into the

windward side of the Big Island, leading to nuisance flooding and

significant stream rises. Up to 7 inches of rain has fallen so far

today at Piihonua, with widespread rainfall amounts of 3 to 6

inches just in the last 6 hours. This is leading to widespread

ponding of water.

* Locations in the advisory include but are not limited to...

the entire windward side of the Big Island, including the Hilo,

Puna, Hamakua and Kau districts.


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


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.


This advisory may need to be extended beyond 900 PM HST if heavy rain
