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

The Flash Flood Watch continues for

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

* Through Sunday afternoon.

* A front will stall over the central islands at the same time as
a potent low aloft moves over the western end of the state. This
will result in periods of heavy showers and thunderstorms that
could result in flash-flooding. Forecast models continue to
indicate that the greatest threat for flooding will occur over
Maui County, but given the unstable environment over the
central and eastern islands, Oahu and The Big Island have the
potential to receive heavy flooding rains as well.

* Heavy rain is expected to be widespread, especially in Maui
County through the weekend. Rain will not only affect windward
areas, but will also impact urban and leeward areas which are
more susceptible to flooding problems, especially in south and
west Maui. These areas include Kihei, Lahaina, Kaanapali, and
low-water crossings along piilani Highway between Kaupo and
Ulupalakua.

Precautionary/preparedness actions...

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

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

* Impacts... moderate... expect strong breaking waves, shore
break, and strong longshore and rip currents making swimming
difficult and dangerous

.Precautionary/preparedness actions...

Beachgoers, swimmers, and surfers should heed all advice given by
ocean safety officials and exercise caution. Boaters should
expect recreational surfers and body boarders utilizing Harbor
channels to access surfing areas.
