... Flash Flood Watch in effect through this afternoon...

The National Weather Service in Honolulu has expanded the

* Flash Flood Watch to include Kahoolawe, Lanai, Maui and

moisture already in place. Slow- moving and persistent heavy
showers and thunderstorms will result in the threat of flash

dangerous and impassible due to severe runoff. Debris in
streams and gulches could clog bridges and culverts resulting
in dangerous flooding. Isolated landslides could also occur.

Precautionary/preparedness actions...

A Flash Flood Watch means that conditions are favorable for flash
flooding. Flash flooding is life threatening. Do not cross fast
