...FLASH FLOOD WATCH IN EFFECT FOR THE BIG ISLAND THROUGH
SATURDAY AFTERNOON...

The National Weather Service in Honolulu has issued a

* Flash Flood Watch for the Big Island.

* Through Saturday afternoon.

* An approaching upper level disturbance will further destabilize
  the air mass, with abundant low-level moisture already in place.
  Slow-moving and persistent heavy showers and thunderstorms will
  bring the threat of flash flooding.

* Heavy rainfall could result in low spots in roads becoming
  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
flowing water in your vehicle or on foot.

Monitor later forecasts and be prepared to take action if a Flash
Flood Warning is issued. If you experience heavy rain or rising
water, head to higher ground immediately.
