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

The Flash Flood Watch continues for

* all of the Hawaiian islands

* through Friday afternoon.

* Low pressure at the surface and aloft to our west will continue
to draw moist tropical air over the islands through at least
Friday. This will lead to periods of heavy rain and possible
thunderstorms.

* The areas at greatest risk are the east and southeast slopes of
all islands, though any given location could experience
excessive rainfall and flash flooding. Areas that recieved
excessive rainfall recently will be more susceptible to flash
flooding since the ground is still saturated.

Precautionary/preparedness actions...

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

Flash flooding is very dangerous. Avoid flood prone areas. Monitor
later forecasts and be prepared to take action should flash flood
warnings be issued.
